Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, when an attacking projectile is launched from a launching aircraft to an object of interest, an enemy ally is identified with respect to the object of interest or an object around the object of interest using a device other than the launching aircraft. It is related with the enemy ally identification satellite which determines whether or not to make an attack flying body self-destruct based on the identified result, a launch mother machine, an ally reporting device, an attack flying object, and an enemy ally identification system.
[0002]
[Prior art]
Conventional example.
Conventionally, when a projectile for launching an attacking flying object against a target object from the launching aircraft, the launching aircraft identifies an enemy ally for the target object and whether or not the attacking projectile self-destructs based on the identified result Had decided. Below, the identification operation of the enemy friend which the launch mother machine is performing is demonstrated.
[0003]
The launch aircraft captures the target object of attack with a radar or the like, and launches a missile toward the captured target object. Based on information such as the position of the target object captured by the launch aircraft, the launched missile will fly to the target object and become autonomous when it reaches a relative distance at which the target object can be captured. Capture the object of interest and continue the guided flight. The launch aircraft is ready to evacuate at this point when the missile autonomously captures the object of interest. However, in a crowded battle situation, there is a possibility that a friendly aircraft will be mistakenly captured as a target object. Also, the target object captured by the launch machine and the target object captured by the missile (in this case, the missile captures the target object captured by the launch machine and the target object captured by the missile. The target object captured by the missile may be a friend machine. Therefore, for the purpose of confirming whether or not a friendly aircraft exists in the vicinity of the target object, the launching aircraft transmits an IFF (Identification Friend or Foe) challenge signal for identifying an enemy ally to the direction of the target object. Send to. When the ally machine detects the IFF challenge signal, it immediately transmits an IFF response signal for responding that it is a ally machine to the launching mother machine. If the IFF response signal is not transmitted, the launch mother machine immediately shifts to the evacuation action. However, when an IFF response signal is detected, a self-destruct command is transmitted to the missile in order to prevent missile capture and explosion. As soon as the missile receives the misfire command, it activates the self-destruction circuit and causes the missile to self-destruct. In this way, allies are avoided.
[0004]
As another conventional technique, there is a flying object with an ally identifying function in which an attacking flying object such as a missile transmits an IFF challenge signal to identify an enemy ally.
[0005]

[0006]
[Problems to be solved by the invention]
As described above, conventionally, the launching aircraft has performed an IFF challenge to avoid the danger of a friendly aircraft. However, despite the fact that evacuation is delayed or impossible to evacuate to ensure the safety of the friendly aircraft, and the missile is able to evacuate early when the target is captured autonomously, There was a problem that improvement of the safety of the mother machine was hindered.
[0007]
In addition, the attacking flying body transmits an IFF challenge signal to avoid the danger of a friendly aircraft. Considering that there are thousands of attack flying bodies used in actual battles, it is considered that the cost of providing these attack flying bodies with a function for identifying enemy ally is enormous.
[0008]
For this reason, the present invention ensures the safety of the launching mother aircraft and the allied aircraft at a lower cost compared to the cost of ensuring the safety of the friendly aircraft along with the launching mother aircraft, as well as the function of identifying the enemy and allies on the attacking flying object The purpose is to secure.
[0009]

1 and 2 is, for example, a quasi-zenith satellite.
[0012]
FIG. 3 is a flowchart showing the operation of each element of the enemy friendly identification system. Hereinafter, the operation of each element of the enemy and friend identification system will be described with reference to FIG.
The launch mother machine 1 launches a missile 2 (S1). At the same time, the launch signal transmitting unit 6 notifies the enemy-friendly identification satellite 5 that the missile 2 has been launched and the data transmitted from the missile 2 (the data from the missile 2 is encrypted with a code). Code information for deciphering is assumed to be transmitted wirelessly (S2, S3).
The enemy and friend identification satellite 5 receives the launch signal 100 and the code information by the launch signal / missile information receiving unit 8 (S10, S11). Thereafter, the enemy-friendly identification satellite 5 enters a standby state for data transmission from the missile 2 (S12).
The missile 2 performs guidance to the target 3 based on the information of the target 3 determined by the launch mother machine 1 and reaches the relative distance at which the target 3 can be captured (S20). When the target 3 is captured (S21), the missile information The target position information 113 indicating the position of the target 3 captured by the transmission unit 7 includes the missile position information indicating its own position and wirelessly transmitted to the enemy ally identifying satellite 5 (S22). However, since the target 3 and the ally machine 4 are close at this time, the missile 2 may erroneously capture the ally machine 4. If the ally machine 4 is erroneously captured, the target position information 113 indicates the position of the ally machine 4.
The enemy-friendly identification satellite 5 wirelessly receives the target position information 113 from the missile 2 (S13) and decodes it by the decoding unit 9 (S14), and then notifies the launch signal / missile information receiving unit 8 of the decoded result. . And the IFF challenge signal 111 which asks the identification of an enemy friend by the question transmission part 10 is radio-transmitted toward the predetermined | prescribed area | region in the direction of the position shown by the target object position information 113 received by S13 (S15).
If there is a teammate in the predetermined area, the teammate 4 wirelessly receives the IFF challenge signal 111 by the question receiver 11 (S30). Immediately after the reception, the response transmission unit 12 includes the response transmission source position information indicating the position of the ally machine 4 in the IFF response signal 112 that responds that it is a friend, and wirelessly transmits it to the enemy ally identifying satellite 5 (S31).
The enemy-friendly identification satellite 5 wirelessly receives the IFF response signal 112 by the response receiver 13 (S16). Then, the enemy ally determination unit 14 analyzes and evaluates the target position information 113 being captured by the missile 2 and the response transmission source position information indicating the position of the ally machine 4, and the missile 2 becomes the ally machine from the positional relationship between the two. It is determined whether 4 is erroneously captured (S17). If there is a possibility that the missile 2 is mistaking the ally machine 4 (S18, YES), the self-destruction command 114 is wirelessly transmitted toward the position of the missile 2 by the self-destruct command transmission unit 15 (S19). The position direction of the missile 2 is determined from the missile position information included in the target position information 113. If it is determined that there is no possibility of mistaking the ally machine 4 (S18, NO), the process branches to S12 to wait for data transmission from the missile 2 or the process of identifying the enemy ally is terminated. .
The missile 2 receives the self-destruction command 114 by the self-destruction command receiver 16 (S23). Then, the self-destructing command receiving unit 16 issues a self-destructing command to the self-destructing circuit unit 17, and the self-destructing circuit unit 17 immediately causes the missile 2 to self-destruct (S24).
[0013]
In the above description of the operation, the missile and the allied aircraft each notified their own position, but the conventional technique in which the position is measured using a satellite (in this case, the satellite is, for example, a geostationary satellite or a quasi-stationary satellite). It is assumed that measurement is performed by a method of positioning a moving object using a zenith satellite. For this reason, detailed description of the positioning method is omitted here.
[0014]
As described above, in this embodiment, in order to avoid the risk that an attacking flying object launched from the launching aircraft erroneously captures or misfires an ally aircraft, the function of identifying an enemy ally and the attacking flying object are self-destructed. Added the ability to command the enemy friendly satellite. Conventionally, a launching mother aircraft or an attacking flying object has a function of identifying an enemy ally and a function of instructing an attacking flying object to detonate. If the launching aircraft has a function to identify enemy ally and a function to command the attacking flying object to self-destruct, after launching the flying object for attacking, the enemy ally is identified and based on the identified result A command was given to make the flying body self-destruct. For this reason, it was not possible to shift to the evacuation action, or the evacuation was delayed. However, in this embodiment, the enemy ally identifying satellite identifies the enemy ally, and issues a command to self-destruct the attacking flying object based on the identified result. As a result, the launch mother aircraft can execute the evacuation action immediately after launching the attacking flying object, and there is an effect that the safety of the launch mother aircraft can be improved.
In the past, it is considered that there was a case where the launch mother aircraft failed to confirm the erroneous capture of the attacking flying object in order to ensure its own safety. However, in this embodiment, since the enemy ally identification satellite performs confirmation of the erroneous capture of the attacking flying object, there is an effect that confirmation of the erroneous capture can be surely performed, and there is an effect that the safety of the friendly aircraft can be improved. .
Further, the range of the area in which the challenge signal is transmitted is determined based on the position of the captured target received by the enemy friendly satellite from the attacking flying object. For this reason, the transmission range of the challenge signal is narrowed down compared to the conventional method in which the range for transmitting the challenge signal is determined based on the position of the target object captured by the launch aircraft itself, and the attacking flying object is reliably captured. The challenge signal can be transmitted to the area including the target.
In addition, if the attacking aircraft has a function to identify an enemy ally and a function to instruct the attacking aircraft to detonate, it will have the above functions on thousands of attacking aircraft. It can be costly. However, when the enemy-friendly identification satellite has the above-mentioned function, it is considered that the cost can be reduced as compared with the case where it is provided with several thousand satellites because it is provided with several satellites.
[0015]
Further, in this embodiment, the enemy-friendly identification satellite is a quasi-zenith satellite, for example. The Quasi-Zenith Satellite is linked to the “Space Cybernetics G” website of the Space Cybernetics Group, Kashima Space Communications Research Center, Communications Research Laboratory (the address of the homepage is “www2.crl.go.jp/ka/index-j.html”). The quasi-zenith satellite “www2.crl.go.jp/ka/control/index-J.html”) is inclined at about 45 degrees from the equator. It goes around once a day according to the rotation of the earth. Note that the inclination angle from the equator plane may be arbitrarily set depending on the design. In addition, as an example, three aircraft are arranged so as to be 120 degrees apart at the ascending intersection eclipse (intersection with the equator plane). The trajectory of the quasi-zenith satellite orbit projected onto the ground surface is such that the quasi-zenith satellite draws an “eight-shape” or “tears pattern” that intersects the equator when the ground is fixed. It is going around. The three quasi-zenith satellites have different orbital planes, but they change over every 8 hours (meetings), so they are located above Japan without a break. Also, when considering the region in Japan, there will always be a quasi-zenith satellite with an elevation angle of 70 degrees or more. Because it is located above Japan without a break, there is always a quasi-zenith satellite with an elevation angle of 70 degrees or more, and when a receiver receives a radio wave from the quasi-zenith satellite on the ground, it is less likely to be blocked in the valleys of the building. . For this reason, when it becomes a battle state over Japan, the safety of the launch aircraft can be secured for 24 hours, and the safety of the friendly aircraft can be secured for 24 hours.
[0016]
Embodiment 2. FIG.
In this embodiment, an example in which an enemy ally is identified by an attacking flying object will be described.
FIG. 4 is a block diagram of the enemy and ally identification system of this embodiment.
The enemy ally identification system shown in FIG. 4 includes a launch mother machine 1, a missile 2, an enemy ally identification satellite 5, an ally machine 4, and a target 3, which is an attack target.
The operation of each element constituting the enemy and friend identification system of FIG. 4 will be briefly described.
In FIG. 4, the teammate 4 is flying in the vicinity of the target 3. The launch mother machine 1 launches a missile 2 as an example of a flying object for attack toward a target 3 that is a target object. Since the missile 2 is flying in the vicinity of the target 3, there is a possibility that the missile 2 erroneously captures the teammate 4. The launch mother machine 1 wirelessly transmits a launch signal 100 that notifies the enemy-friendly identification satellite 5 that the missile 2 has been launched. At this time, the launch signal 100 includes information indicating the position of the target object captured by the launch mother machine 1. The enemy friend identification satellite 5 wirelessly transmits an IFF (Identification Friends for Foe) challenge signal 111 which is a challenge signal for inquiring about the identification of the enemy friend. The range in which the challenge signal is wirelessly transmitted is a predetermined area in the position direction of the target object based on the information indicating the position of the target object included in the emission signal 100. However, the challenge signal of the first embodiment is transmitted. The predetermined area is wider than the area to be processed. This is because the information from which the range is determined is not the position of the target captured by the missile 2 but the position of the target object captured by the launch mother machine 1.
Upon receiving the IFF challenge signal 111, the ally machine 4 wirelessly transmits the response transmission source position information indicating its own position in the IFF response signal 112 that responds that it is a friend. Upon receiving the IFF response signal 112, the enemy teammate satellite 5 takes out the response transmission source position information 115 included in the IFF response signal 112 and wirelessly transmits it to the missile 2. Since the missile 2 is close in position between the target 3 and the teammate 4, it is considered that the teammate 4 may be erroneously captured. Therefore, based on the position information of the target captured by itself and the response transmission source position information 115 wirelessly received from the enemy ally identifying satellite 5, it is determined whether or not the ally machine 4 is erroneously captured. As a result of the determination, if it is determined that there is a possibility that the ally machine 4 is erroneously captured, the missile 2 performs a self-destruction.
[0017]

The firing signal receiving unit 200 includes a firing signal receiving unit 18. In addition, the enemy-friendly identification satellite 5 includes a question transmitting unit 10 that wirelessly transmits an IFF challenge signal 111 to the ally machine 4 to inquire about an enemy ally. The enemy friendly identification satellite 5 includes a response receiving unit 13 that wirelessly receives an IFF response signal 112 that responds to an IFF challenge signal from the ally machine 4. The enemy team identification satellite 5 includes a teammate machine information transmission unit 19 that wirelessly transmits response source position information 115 indicating the position information of the teammate machine 4 to the missile 2. The response source location information 115 is included in the IFF response signal 112. The identification processing unit 202 includes an ally machine information transmission unit 19.
The missile 2 includes an ally machine information receiving unit 20 that wirelessly receives the response transmission source position information 115 wirelessly transmitted from the enemy ally identifying satellite 5. Further, the missile 2 compares the position of the target captured by the missile 2 with the position of the teammate 4 according to the response transmission source position information 115, and determines whether or not to make the missile self-destruct based on the comparison result. The enemy ally determination unit 21 is provided. In addition, the missile 2 includes a self-destruction circuit unit 17 that causes the missile 2 to self-destruct according to the determination result of the enemy teammate determination unit 21.
The ally machine 4 receives the IFF challenge signal 111 wirelessly transmitted from the enemy ally identifying satellite 5 and the IFF response signal 112 that responds to the received IFF challenge signal 111 that it is a ally machine. The ally reporting device 203 includes a response transmission unit 12 that wirelessly transmits information including the position of the ally machine 4 itself.
4 and 5 is, for example, a quasi-zenith satellite.
[0018]
FIG. 6 is a flowchart showing the operation of each element of the enemy friendly identification system. Hereinafter, the operation of each element of the enemy and friend identification system will be described with reference to FIG.
The launch mother machine 1 launches a missile 2 (S1). At the same time, the launch signal transmitting unit 6 wirelessly transmits the launch signal 100 for notifying the enemy-friendly identification satellite 5 that the missile 2 has been launched (S2). The launch signal 100 includes information indicating the position of the target object captured by the launch mother machine 1.
The enemy friendly identification satellite 5 receives the emission signal 100 by the emission signal receiver 18 (S10).
The enemy-friendly identification satellite 5 wirelessly transmits the IFF challenge signal 111 for inquiring about the identification of the enemy and allies by the question transmitting unit 10 (S15). At this time, using the information indicating the position of the target object received by the emission signal receiving unit 18, the IFF challenge signal 111 is wirelessly transmitted toward a predetermined area including the position of the target object in the direction of the target object.
The ally machine 4 wirelessly receives the IFF challenge signal 111 by the question receiving unit 11 (S30). Immediately after the reception, the response transmission unit 12 includes the response transmission source position information indicating the position of the ally machine 4 in the IFF response signal 112 that responds that it is a friend, and wirelessly transmits it to the enemy ally identifying satellite 5 (S31).
The enemy-friendly identification satellite 5 wirelessly receives the IFF response signal 112 by the response receiver 13 (S16). Then, the friend machine information transmission unit 19 extracts the response transmission source position information 115 from the received IFF response signal 112 and wirelessly transmits it to the missile 2 (S40).
The missile 2 receives the response source position information 115 wirelessly transmitted from the enemy team identification satellite 5 by the ally machine information receiving unit 20 (S50). The enemy friend determination unit 21 analyzes and evaluates the positional relationship between the target 3 being captured by the missile 2 and the friend machine 4 indicated by the response transmission source position information 115 (S51). As a result of the analysis and evaluation, if it is determined that there is a possibility that the missile 2 has mistaken the ally machine 4 (S52, YES), the enemy ally determination unit 21 operates the self-destruction circuit unit 17 to cause the missile 2 to detonate. . If it is determined in S52 that there is no possibility that the ally machine 4 is erroneously captured (S52, NO), the process for identifying the enemy ally is terminated.
[0019]
In the above description of the operation, the missile and the allied aircraft each measured their own position, but their own position is measured using satellites (in this case, even if the satellite is a quasi-zenith satellite) (It may be a geostationary satellite.) It is assumed that measurement is performed by a method of positioning a moving object by a conventional technique. For this reason, detailed description of the positioning method is omitted here.
[0020]
As described above, in this embodiment, in order to avoid the danger that the attacking projectile launched from the launching aircraft erroneously captures or misfires the ally aircraft, the enemy ally identification satellite is provided with a function to query the enemy ally. The attacking flying object is provided with a function for determining an enemy ally and a function for instructing the attacking flying object to detonate. Conventionally, when equipped with a function to ask the launching aircraft about the enemy ally, a function to identify the enemy ally, and a function to command the attacking flying object to self-destruct, the launching mother aircraft cannot shift to evacuation behavior, I was evacuating late. However, the attacking flying object identifies an enemy ally and causes the attacking flying object to self-destruct based on the identified result. As a result, the launch mother aircraft can execute the evacuation action immediately after launching the attacking flying object, and there is an effect that the safety of the launch mother aircraft can be improved.
In the past, it is considered that there was a case where the launch mother aircraft failed to confirm the erroneous capture of the attacking flying object in order to ensure its own safety. However, in this embodiment, since the attacking flying object performs confirmation of the erroneous capture of the attacking flying object, there is an effect that confirmation of the erroneous capturing can be surely performed, and there is an effect that the safety of the friendly aircraft can be improved. .
In addition, the enemy-friendly satellite has a function to ask questions to identify enemy ally. For this reason, the cost of having a function to ask an enemy ally and a function to determine an enemy ally to thousands of flying aircraft and a cost to have a function to ask an enemy ally to several satellites And the latter cost can be reduced.
[0021]
Further, in this embodiment, the enemy-friendly identification satellite is a quasi-zenith satellite, for example. The Quasi-Zenith Satellite is linked to the "Space Cybernetics G" homepage by the Space Cybernetics Group, Kashima Space Communications Research Center (the address of the homepage is "www2.crl.go.jp/ka/index-j.html"). The quasi-zenith satellite “www2.crl.go.jp/ka/control/index-J.html”) is inclined at about 45 degrees from the equator. It goes around once a day according to the rotation of the earth. Note that the inclination angle from the equator plane may be arbitrarily set depending on the design. In addition, as an example, three aircraft are arranged so as to be 120 degrees apart at the ascending intersection eclipse (intersection with the equator plane). The trajectory of the quasi-zenith satellite orbit projected onto the ground surface is such that the quasi-zenith satellite draws an “eight-shape” or “tears pattern” that intersects the equator when the ground is fixed. It is going around. The three quasi-zenith satellites have different orbital planes, but they change over every 8 hours (meetings), so they are located above Japan without a break. Also, when considering the region in Japan, there will always be a quasi-zenith satellite with an elevation angle of 70 degrees or more. Because it is located above Japan without a break, there is always a quasi-zenith satellite with an elevation angle of 70 degrees or more, and when the receiver receives radio waves from the quasi-zenith satellite on the ground, it is less likely to block the radio waves even in the valleys of the building. . For this reason, when it becomes a battle state over Japan, the safety of the launch aircraft can be secured for 24 hours, and the safety of the friendly aircraft can be secured for 24 hours.

Embodiment 3 FIG.
In this embodiment, an example in which an enemy ally is determined by an ally machine will be described.
FIG. 7 is a block diagram of the enemy and ally identification system of this embodiment. The operation of each element constituting the enemy and friend identification system of FIG. 7 will be briefly described.
In FIG. 7, the teammate 4 is flying in the vicinity of the target 3. The launch mother machine 1 launches a missile 2 as an example of a flying object for attack toward a target 3 that is a target object. The launch mother machine 1 wirelessly transmits a launch signal 100 that notifies the enemy-friendly identification satellite 5 that the missile 2 has been launched. The missile 2 wirelessly transmits target position information 113 for notifying its own position and the position of the captured target to the enemy-friendly identification satellite 5. As described above, since the positions of the target 3 and the ally machine 4 are close, the missile 2 may erroneously capture the ally machine 4. For this reason, the position of the captured target may indicate the position of the teammate 4. Based on the target position information 113 received from the missile 2, the enemy ally identifying satellite 5 is a challenge signal that asks for identification of the enemy ally toward a predetermined area in the direction of the position of the captured target. IFF: Id e (nification friend or fore)) wirelessly transmits a challenge signal 111. At this time, the target position information 113 received from the missile 2 is included in the IFF challenge signal 111. The teammate 4 in the predetermined area receives the IFF challenge signal 111. Then, the ally machine 4 analyzes the target position information 113 and its own position, and analyzes the positional relationship between the ally machine 4 and the missile 2. As a result of the analysis, if it is determined that there is a possibility that the missile 2 has mis-acquired the ally machine 4, the missile 2 has mis-acquired the ally machine 4 in the IFF response signal 116 that responds that it is a ally machine. Is transmitted wirelessly to the enemy-friendly identification satellite 5. If it is determined that there is no possibility that the missile 2 has mis-acquired the ally machine 4, an IFF response signal 116 is sent to the enemy ally identifying satellite 5 as a response indicating that it is a ally machine. The enemy-friendly identification satellite 5 receives the IFF response signal 116, and if the IFF response signal 116 includes information indicating that the missile 2 has mis-acquired the friendly aircraft 4, Self-destruct command 114 is transmitted by radio. The missile 2 self-destructs when receiving a self-destruct command by radio.

FIG. 9 is a flowchart showing the operation of each element of the enemy teammate identification system. Hereinafter, the operation of each element of the enemy and friend identification system will be described with reference to FIG.
The launch mother machine 1 launches a missile 2 (S1). At the same time, the launch signal transmitting unit 6 notifies the enemy-friendly identification satellite 5 that the missile 2 has been launched and the data transmitted from the missile 2 (the data from the missile 2 is encrypted with a code). Code information for deciphering is assumed to be transmitted wirelessly (S2, S3).
The enemy and friend identification satellite 5 receives the launch signal 100 and the code information by the launch signal / missile information receiving unit 8 (S10, S11). Thereafter, the enemy-friendly identification satellite 5 enters a standby state for data transmission from the missile 2 (S12).
The missile 2 performs guidance to the target 3 based on the information of the target 3 determined by the launch mother machine 1 and reaches the relative distance at which the target 3 can be captured (S20). When the target 3 is captured (S21), the missile information The target position information 113 including the missile position information indicating its own position is included in the target position information 113 indicating the position of the target 3 captured by the transmission unit 7 and wirelessly transmitted to the enemy ally identifying satellite 5 (S22). However, at this time, since the target 3 and the teammate 4 are close to each other, the missile 2 may erroneously capture the teammate 4. If the ally machine 4 is mistakenly captured, the target position information 113 indicates the position of the ally machine 4.
The enemy-friendly identification satellite 5 wirelessly receives the target position information 113 from the missile 2 (S13) and decodes it by the decoding unit 9 (S14), and then notifies the launch signal / missile information receiving unit 8 of the decoded result. . Then, the question transmission unit 10 wirelessly transmits an IFF challenge signal 111 for inquiring about the identification of an enemy ally (S15). At this time, the question transmitting unit 10 includes the target position information 113 in the IFF challenge signal 111 and wirelessly transmits it. In addition, the question transmission unit 10 wirelessly transmits the IFF challenge signal 111 toward a predetermined area in the direction of the position of the target that the missile 2 of the target position information 113 has captured.
The ally machine 4 wirelessly receives the IFF challenge signal 111 by the question receiving unit 11 (S30). After reception, the enemy teammate determination unit 22 extracts the target position information 113 included in the IFF challenge signal 111, and information indicating the position of the target captured by the missile 2 of the target position information 113 and the friend machine. 4 Analyzes and evaluates the information indicating the position of itself, and compares the positional relationship between the two (S60). When it is determined that there is a possibility that the missile 2 has mis-acquired the teammate 4 (S61, YES), the response transmitter 12 sends the missile 2 to the IFF response signal 112 that responds that it is a friend. The information indicating that there is a possibility of erroneously capturing the aircraft 4 is wirelessly transmitted to the enemy friendly identification satellite 5 (S62). If there is no possibility that the missile 2 has mis-acquired the ally machine 4, the response transmission unit 12 wirelessly transmits an IFF response signal 112 that responds that it is a friend to the enemy ally identifying satellite 5.
The enemy teammate satellite 5 wirelessly receives the IFF response signal 116 by the response receiver 13. After reception, the self-destruct command transmission unit 15 confirms whether or not the IFF response signal 116 includes information indicating that the missile 2 may have mis-acquired the friend 4 (S70). In the case (S70, YES), the self-destruction command 114 is wirelessly transmitted toward the position of the missile 2 (S19). If not included (S70, NO), the process is terminated. Alternatively, the process branches to S12 and waits for notification from the missile 2.
The missile 2 receives the self-destruction command 114 by the self-destruction command receiver 16 (S23). Then, the self-destructing command receiving unit 16 issues a self-destructing command to the self-destructing circuit unit 17, and the self-destructing circuit unit 17 immediately causes the missile 2 to self-destruct (S24).
[0025]
In the above description of the operation, the missile and the allied aircraft each notified their own position, but their position was measured conventionally (the satellite in this case is a quasi-zenith satellite) It is assumed that the measurement is performed by a method of positioning a moving object using a geostationary satellite. For this reason, detailed description of the positioning method is omitted here.
[0026]
As described above, in this embodiment, in order to avoid a risk that the attacking aircraft launched from the launch aircraft erroneously captures / explodes the ally aircraft, whether or not the attacking aircraft erroneously captures the ally aircraft. The ally machine has a function to determine whether or not, and the enemy ally identification satellite has a function to inquire about an enemy ally and a function to instruct the attacking flying object to detonate. Conventionally, the launch mother aircraft has a function to identify enemy ally and a function to command the attacking aircraft to self-destruct, and after launching the attacking aircraft, the launching aircraft identifies the enemy ally, Based on this, he was instructed to self-destruct the flying object for attack. For this reason, it was not possible to shift to the evacuation action, or the evacuation was delayed. However, the ally aircraft determines whether or not the attacking flying object has mis-acquired the ally aircraft, and the enemy ally identifying satellite issues a command to cause the attacking flying object to detonate according to the determination result. As a result, the launch mother aircraft can execute the evacuation action immediately after launching the attacking flying object, and there is an effect that the safety of the launch mother aircraft can be improved.
In the past, it is considered that there was a case where the launch mother aircraft failed to confirm the erroneous capture of the attacking flying object in order to ensure its own safety. However, in this embodiment, since the ally machine confirms the erroneous capture of the attacking flying object, there is an effect that the confirmation of the erroneous capture can be surely performed, and the safety of the ally machine can be improved.
Conventionally, the challenge is determined so that the signal transmission range is a wide range based on the position of the target object captured by the launch aircraft. This is intended for a wide range in consideration of the case where the target object captured by the launch aircraft is different from the target captured by the attack flying object. However, in this embodiment, the range in which the challenge signal is transmitted is determined based on the position of the target captured by the attacking flying object. As a result, the range in which the challenge signal is transmitted can be narrower than the above-described conventional range, and can be transmitted to the target captured by the attacking flying object with certainty. Also, compared to the cost of having a function to ask enemy teammates for thousands of aircrafts for attack and a function to determine enemy teammates, it has a function to ask enemy teammates about the enemy team. At the same time, it is possible to keep the cost low in the case where a smaller number of allied aircraft than the attacking flying object is provided with a function for judging enemy ally.
[0027]
Further, in this embodiment, the enemy-friendly identification satellite is a quasi-zenith satellite, for example. The Quasi-Zenith Satellite is linked to the "Space Cybernetics G" homepage by the Space Cybernetics Group, Kashima Space Research Center, Communications Research Laboratory (the address of the homepage is "www2.crl.go.jp/ka/index-j.html"). The quasi-zenith satellite “www2.crl.go.jp/ka/control/index-J.html”) is inclined at about 45 degrees from the equator. It goes around once a day according to the rotation of the earth. Note that the inclination angle from the equator plane may be arbitrarily set depending on the design. Also, as an example, three aircraft are arranged so as to be 120 degrees apart at the ascending intersection eclipse (intersection with the equator plane). The trajectory of the quasi-zenith satellite orbit projected onto the ground surface is such that when the ground is fixed, the quasi-zenith satellite draws an “eight-shape” or “tears pattern” that intersects the equator. It is going around. The three quasi-zenith satellites are located above Japan seamlessly by changing (meeting) every eight hours, but with different orbital planes. Also, when considering the region in Japan, there will always be a quasi-zenith satellite with an elevation angle of 70 degrees or more. Because it is located above Japan without a break, there is always a quasi-zenith satellite with an elevation angle of 70 degrees or more, and when the receiver receives radio waves from the quasi-zenith satellite on the ground, it is less likely to block the radio waves even in the valleys of the building. . For this reason, when it becomes a battle state over Japan, the safety of the launch aircraft can be secured for 24 hours, and the safety of the friendly aircraft can be secured for 24 hours.
[0028]
Embodiment 4 FIG.
In the first to third embodiments, the teammate 4 and the target 3 are close to each other. However, as shown in FIG. 10, only the friendly machine 4 may be used. In FIG. 10, the objects captured by the launch mother machine 1 and the missile 2 are the same as those in the first to third embodiments in that they are the same. However, it is possible to determine that the missile 2 has mistakenly captured the ally machine 4 by any of the enemy and friend identification systems described in the first to third embodiments, and to make the missile 2 self-destruct.
Moreover, in the said Embodiment 1-3, although the ally machine 4 was 1 machine, you may have multiple machines. If there are a plurality of allies and their positions are close to each other, the missile will self-destruct when a response that is a friend is made by at least one friend. Alternatively, when it is notified from at least one ally machine that the missile has mis-acquired the ally machine, the missile self-destructs.
Also, in actual combat conditions, it can be expected that missile attacks will be carried out in all directions. For this reason, it is assumed that the enemy friendly satellite can monitor a plurality of missiles.
[0029]
Embodiment 5 FIG.
In the above-described first to fourth embodiments, the attacking flying object, for example, the launching aircraft that launches the missile is the flying object. However, if the launch vehicle is capable of launching a flying object for attack and moving, it can be a tank, submarine, ship, or person (in the case of a person, the person moves with an attack device that fires a tracking bullet, for example). But it doesn't matter.
In the first to fourth embodiments, the attacking flying object is a missile. However, it may not be a missile as long as it can be tracked while capturing a target by itself.
In the first to fourth embodiments, the enemy and friend identification satellite is, for example, a quasi-zenith satellite, but is not limited to a satellite and may be a base station or a building.
Moreover, in the said Embodiment 1-4, although the target and the friend machine were movable, you may not move, such as a building. Further, any device that can transmit and receive radio waves may be used in the sea or in the ground.
[0030]
【The invention's effect】
As described above, the enemy ally identifying satellite according to the present invention identifies an enemy ally with respect to a target captured by the attacking flying object instead of the launching aircraft or the attacking flying object, and erroneously captures the ally. If it is, it will detonate the attacking flying object. For this reason, there is an effect of improving the safety of the launch mother machine. In addition, there are thousands of attack flying bodies, but several enemy friendly satellites. For this reason, compared to the cost required to mount an attacking flying object with a function for identifying an enemy ally with respect to a target captured by the attacking flying object, the cost of preparing several satellites is reduced. There is an effect that can be suppressed.
