2. Description of the Related Art The prior art according to the present invention is applied to a missile decoy system or the like. FIG. 13 is a block diagram showing a missile decoy system disclosed in, for example, JP-A-1-148596. In FIG. 13, three decoys (simulated targets) 17-1, 17-2, 1
7-3 are located in several places near the radar 18. Each of the decoys 17-1, 17-2, and 17-3 is a data link, in this example, the cables 19-1 and 19-3.

issile) to irradiate 19, RF of predetermined frequency
1 is a conventional pulse radar that emits a pulse signal having a signal. A synchronizer 20 in the radar 18 is configured to control a transmitter 22 that produces a pulse signal fired by an antenna 21. In addition, the synchronization device 20
The decoys 17-1, 17-2, and 17-3 are controlled so that the decoy pulse having the RF signal of a predetermined frequency and the pulse signal are generated in a predetermined order. FIG. 14 is a timing chart of emission of the decoy pulse and the pulse signal.

A guidance system 19A installed inside the ARM 19 generates a guidance command for homing the ARM 19 to a source of an RF signal pulse to be irradiated with the ARM 19. Thus, if only the radar 18 generates a pulse signal, the guidance system 19A will track the radar 18 in response to a preselected portion of the pulse signal, ie, the leading edge, trailing edge or middle portion of the pulse,
A guidance command for homing the ARM 19 to the radar 18 is generated. However, in this example, the synchronizer 20 is configured to generate a trigger pulse (not shown) for each of the transmitter 22 and the decoys 17-1, 17-2, and 17-3. Due to this trigger pulse, each of the decoys 17-1, 17-2, and 17-3 causes FIG.
As shown in (c) and (d), a decoy pulse is generated before, during, and after the pulse signal. As a result, apparent A
The RF signal pulse applied to the RM 19 is as shown in FIG.
As shown in the figure, the pulse signal and the decoys 17-1, 17-
It becomes a composite signal of the decoy pulses of 2, 17-3. Accordingly, in the RF signal pulse received by the guidance system 19A of the ARM 19, the pulse signal from the radar is covered by the decoy pulse from the decoy, and the predetermined position (front edge, rear edge, middle ) Cannot be detected (because an edge or the like of a synthesized pulse different from the predetermined position of the pulse signal is detected), and tracking of the radar 18 becomes difficult, and the radar 18 is directed to a ground collision position distant from the radar 18. Will be done.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 FIG. 1 is a block diagram of a radio wave emission control system according to Embodiment 1 of the present invention. Reference numeral 1 denotes a plurality of radio wave emission sources which emit radio waves in synchronization with each other according to the present invention. A radio wave emission device (3 types in this embodiment), 3 is a launch control device that controls the emission of simulated radio waves of the radio wave emission devices 2-1, 2-2, 2-1-1, 2-2, and 2-3; 4 is a radio wave emission source 1
A data link for transmitting a timing signal of the radio wave emission to the emission control device 3; a timing generation circuit 5 for generating a simulated radio wave emission timing signal of the radio wave emission device for the timing signal transmitted from the data link 4; −
Reference numerals 1, 6-2 and 6-3 are data links for transmitting a simulated radio wave emission timing signal from the emission control device 3 to the radio wave emission devices 2-1, 2-2 and 2-3.

Next, the operation of this embodiment will be described. A timing signal of the radio wave emission from the radio wave emission source 1 is transmitted to the emission control device 3 via the data link 4. The emission control device 3 generates a simulated radio wave emission timing signal to each radio wave emission device from the timing signal in the timing generation circuit 5, and the data link 6
It transmits to each radio wave emission device via 1, 6-2 and 6-3. The radio wave launchers are data links 6-1, 6-2, 6-
The simulated radio wave emission is performed based on the simulated radio wave emission timing signal transmitted from 3.

As described above, the timing of the radio wave emission from the radio wave emission source 1 can be sent to only the emission control device 3 via the data link 4. Therefore, when the radio wave emission source 1 moves, the data link 4 must be secured. It has the effect of being able to move easily.

Embodiment 2 FIG. 2 shows the configuration of the second embodiment of the present invention. In this embodiment, a large number of radio wave emission devices are arranged, and the position information of the radio wave emission source is transmitted via the data link 4 as the radio wave emission source 1 moves.
By providing the emission control device 3 with the selection control unit 7 that optimally selects the radio wave emission device to be used from the position information of the radio wave emission source according to the purpose, the radio wave emission device to be used is moved with the movement of the radio wave emission source. It has the effect of being optimally selected and capable of moving over a wide area. The selection of the radio wave emitting device is performed, for example, by preferentially selecting a radio wave emitting device arranged near the periphery of the radio wave emitting source 1. This is because the viewing angle at which the ARM can receive radio waves is limited, so even if a simulated radio wave is emitted from a radio wave emission device that is too far from the radio wave emission source, it will not be received by the ARM and the radio wave emission device will function as a decoy. This is because it will no longer be possible. Therefore, when the radio wave emission source moves, the radio wave emission devices around it also change, so that the selected radio wave emission device also changes. In this embodiment, the most suitable radio wave emitting device is selected from the position information. However, the same effect can be obtained by transmitting necessary information from the radio wave emitting source 1 according to the purpose.

Embodiment 3 FIG. 3 is a block diagram of an example of the third embodiment of the present invention. In the figure, reference numeral 8 denotes a detection receiving unit that detects the radio wave emission of the radio wave emission source 1,

The radio wave emission source 1 emits a radio wave, and the detection and reception unit 8 receives the emitted radio wave as an RF signal. Detection receiving unit 8
Then, the timing at which the RF signal is received is sent to the timing generation circuit 5 as a detection timing signal. The timing generation circuit 5 generates a simulated radio wave emission timing signal of each radio wave emission device in synchronization with the detection timing, and sends it to the radio wave emission device via the data links 6-1, 6-2 and 6-3. A simulated radio wave having the same frequency as the radio wave from the radio wave emission source 1 is transmitted from each radio wave emitting device based on the simulated radio wave emission timing signal.

As described above, in the configuration of this embodiment, the data link 4 between the radio wave emission source 1 and the emission control device 3 becomes unnecessary, and the radio wave emission source 1 does not need to send a radio wave emission timing signal. This has the effect of reducing the cost of the data link 4 and the cost of the radio wave emitting source 1.

Embodiment 4 FIG. 4 is a block diagram of an example of the fourth embodiment of the present invention. In the figure, 5 receives the emission timing signals of the plurality of radio emission sources, receives the radio emission timing signals of the respective radio emission sources 1-1 and 1-2 via the data links 4-1 and 4-2, The timing generation circuit transmits a simulated radio wave emission timing signal synchronized with the timing signal to each radio wave emission device. Note that components having the same numbers as those in the first embodiment operate similarly.

Next, the operation of this embodiment will be described.
The timing of radio wave emission from the radio wave emission sources 1-1 and 1-2 is sent to the emission control device 3 via the data links 4-1 and 4-2, respectively. The emission control device 3 generates a simulated radio wave emission timing signal synchronized with each simulated radio wave emission timing in the timing generation circuit 5 from the radio wave emission timing signal and transmits the simulated radio wave emission timing signal to the radio wave emission device. Simulated radio wave emission is performed based on this. Note that the frequency of the radio wave emitted from each radio wave emission source may be different. However, in this case, the radio wave emitting device needs to be able to cope with any of the different frequencies.

As described above, in the configuration of this embodiment, the radio wave emitting device can be used in common for a plurality of radio wave emitting sources, and the cost can be reduced.

Embodiment 5 FIG. Next, the configuration of a fifth embodiment of the present invention is shown in FIG. In this embodiment, a large number of radio wave emission sources are arranged, and the position information of the radio wave emission source is transmitted via the data link 4 as the radio wave emission source moves. In the emission control device 3, there is provided a selection control unit 7 for optimally selecting the radio wave emission device to be used according to the purpose from the position information of each radio wave emission source. In addition, by providing the emission control device 3 with a specification setting unit for transmitting simulated radio emission specifications such as a frequency to each selected radio emission device,
With the movement of the radio wave emission source, the radio wave emission device to be used is optimally selected, and there is an effect that the radio wave emission source can be moved over a wide range. In this embodiment, the most suitable radio wave emitting device is selected from the position information. However, the same effect can be obtained by transmitting necessary information from the radio wave emitting source 1 according to the purpose.

Embodiment 6 FIG. FIG. 6 is a block diagram of an example of Embodiment 6 of the present invention. In the figure, reference numeral 8 denotes a detection / reception unit provided in the radio wave emission device for detecting the radio wave emission of the radio wave emission source 1, and 9 denotes a data link 6-1 and 6 provided between the radio wave emission device and the emission control device 3. -2, 6
An interface unit for transmitting and receiving via the interface 3; a transmission unit 10 for emitting radio waves; 11 a transmission / reception switching circuit for switching the operation of the detection / reception unit 8 and the transmission unit 10 based on a control signal from the emission control device 3; A synchronization control unit provided in the device 3 for synchronizing the switching timing of the detection reception unit 8 and the transmission unit 10 of the radio wave emission device with a plurality of radio wave emission devices;
Is a selection control unit that selects a radio wave emission device to be used based on the detection information from the detection reception unit 8, and 13 is a emission control device.
An interface unit for transmitting and receiving data and the like to and from each radio wave emitting device. Note that components having the same numbers as those in the first embodiment operate similarly.

Next, the operation of this embodiment will be described.
Detecting and receiving unit 8 of each radio wave emitting device 2-1, 2-2, 2-3
, The radio wave emission of the radio wave emission source 1 is detected. next,
The detection information is transferred to the interface unit 9 and the data link 6
1, 6-2, 6-3, via the interface unit 13,
Send to selection control unit 7. The selection control unit 7 selects a detectable radio wave emission device from the detection information (for example, reception level) from each radio wave emission device, and transmits an operation command to each radio wave emission device. The synchronization control unit 12 generates a synchronization signal for switching between the transmission unit 10 and the detection and reception unit 8 for the selected radio wave emission device, and transmits the synchronization signal to the transmission / reception switching circuit 11. The transmission / reception switching circuit 11 controls the operations of the detection reception unit 8 and the transmission unit 10 based on the synchronization timing from the synchronization control unit 12. Detection receiving unit 8
, When the radio wave of the radio wave emission source is detected, the transmitting unit 1
Simulated radio wave emission is performed from 0, and transmission of the simulated radio wave is continued until the switching time based on the synchronization timing. After the transmission is stopped, the detection and reception section 8 starts radio wave detection of the radio wave emission source.
That is, while the detection and reception unit in the radio wave emission device is operating, the other radio wave emission devices are controlled so as not to drive the transmission unit and not to emit the simulated radio wave. As described above, since the launch control is performed under the centralized control in the synchronization control unit 12,
A transmission phenomenon in which a plurality of launch devices detect and transmit each other's radio waves does not occur.

As described above, in the configuration of this embodiment, instead of using the position information from the radio wave emission source, the emission control device detects the radio wave emission of the radio wave emission source by the radio wave emission device, thereby detecting the radio wave emission. Since a simulated radio wave can be emitted by selecting a radio wave emitting device capable of performing the above, it is possible to cope with a movement of a radio wave emitting source or the like.

Embodiment 7 Next, a configuration of a seventh embodiment of the present invention is shown in FIG. In this embodiment, the detection receiving unit 8
Instead of this, the azimuth measuring unit 14 is provided in the radio wave emitting device. The azimuth measuring unit 14 measures the azimuth of arrival of the radio wave from the radio wave emission source 1 and transmits the azimuth information to the emission control device 3. The selection control unit 7 in the emission control device 3 identifies the azimuth from the radio wave emission source 1 based on the azimuth information, and selects a radio wave emission device suitable for emitting the simulated radio wave. In the selected radio wave emission device, the direction measurement unit 14 receives the radio wave from the radio wave emission source and the simulated radio wave from another (selected) radio wave emission device. Based on the result of this selection, the transmission / reception switching circuit 11 performs the following radio emission control of the transmission unit 8. That is, the direction measuring unit 14 identifies the direction of arrival of the radio wave from the radio wave emitting source and the direction of arrival of the simulated radio wave from another radio wave emitting device. As a result of this identification, when a radio wave from a radio wave emission source is received, the transmission / reception switching circuit is driven to emit a simulated radio wave from the transmission unit 8. on the other hand,
When a simulated radio wave from another radio wave emitting device is received, the transmission / reception switching circuit is not driven and the simulated radio wave is not emitted from the transmission unit 8. As a result, it is possible to distinguish between a radio wave from a radio wave source or a simulated radio wave from another radio wave transmitter without synchronizing the transmission / reception switching timing of each radio wave transmitter, so that oscillation phenomenon does not occur. Can be.

Therefore, a synchronization control unit is not required in the launch control device 3, and the same effects as in the sixth embodiment can be obtained. Further, even when there are a plurality of radio wave emission sources, the radio waves can be identified by the azimuth and the same effect can be obtained.

Embodiment 8 FIG. FIG. 8 is a block diagram of an example of the eighth embodiment of the present invention. In the figure, 15
Is a command control unit for commanding each radio wave emission device to emit a radio wave based on the detection information from the detection reception unit of the radio wave emission device 3 in the emission control device. Components having the same numbers as those in the first embodiment operate similarly.

Next, the operation of this embodiment will be described.
The detection receiving unit in the radio wave emission device detects the radio wave of the radio wave emission source in the same manner as the other embodiments described above, and transmits it to the emission control device. In the emission control device, the selection control unit 7 selects a radio emission device capable of detecting a radio emission source. In this case, one radio emission device with the best reception condition is selected. For example, when there are a plurality of radio emission sources, a radio emission device that can detect all the radio emission sources is selected. Based on the detection information of the detection receiving unit of the selected radio wave emitting device, the command control unit 15 transmits a firing command including other radio wave emitting devices at the detected timing and performs synchronous firing from a plurality of radio wave firings. .

In the present embodiment, since the configuration is as described above, it is not necessary for all the radio wave emitting devices that perform radio wave emission to detect the radio wave of the radio wave emitting source. The same effect as that of the sixth embodiment can be obtained by further providing the degree of freedom in the arrangement. Similar effects can be obtained by replacing the detection receiver 8 with the azimuth detector 14 as in the seventh embodiment.

Embodiment 9 Next, the configuration of the ninth embodiment is shown in FIG. In this embodiment, an azimuth measuring unit 14 is provided in the radio wave emitting device in place of the detection receiving unit 8 to measure the arrival direction of the radio wave from the radio wave emitting source 1, and from the azimuth measurement result of each radio wave emitting device, A radio locating unit 16 for locating the radio wave is provided, and from this locating result, it is determined whether or not the radio wave source is assigned to each radio wave emitting device, a firing command is issued from the firing command control unit, and the radio wave is emitted from the radio wave emitting device. Control. This makes it possible for the assigned radio wave emitting devices to accurately emit radio waves to a plurality of radio wave emission sources.

Therefore, the same effects as in the eighth embodiment can be obtained even in the case of the arrangement of each device in which it is difficult to identify the direction.

Embodiment 10 FIG. FIG. 10 is a block diagram of an example of the tenth embodiment of the present invention. In the figure, the detection receiving unit 8 is configured to receive not only a radio wave emitting source but also a simulated radio wave emitted by another radio wave emitting device. Components having the same numbers as those in the first embodiment operate similarly.

Next, the operation of this embodiment will be described.
By the synchronization control unit 12, for example, the switching operation of transmission and reception of each radio wave emitting device operates at the timing shown in FIG. A radio emission prohibition time is provided, this period is provided to detect the radio wave emission status of the radio wave emission source, radio waves can be emitted at other times, radio waves will be emitted if detected by the detection reception unit, and if not detected It will continue until it is detected. For example, when the radio wave emitting devices 2-2 and 2-3 cannot detect the radio wave of the radio wave emitting source and only the radio wave emitting device 2-1 can detect the radio wave, as shown in FIG. The emission device 1-1 detects the emission of the radio wave from the radio wave emission source, and starts the radio wave emission after the end of the radio wave emission prohibition time. Since the other radio wave emitting devices 2-2 and 2-3 cannot detect the radio wave emission of the radio wave emission source, the detection is continued even after the radio wave emission prohibition time ends, and the simulated radio wave emission of the radio wave emission device 2-1 is detected. To start simulated radio wave emission. After the start, all the radio wave emitting devices continue firing until the radio wave emission prohibition time, stop, and perform detection during the radio wave emission prohibition time.

Therefore, in the above-described embodiment, since it is configured as described above, it is not necessary for all the radio wave emission devices to detect the radio wave emission source, and further, the emission control device does not need to provide the emission command, and the seventh embodiment is different from the seventh embodiment. Similar effects can be obtained.

Embodiment 11 FIG. Next, a configuration of an eleventh embodiment of the present invention is shown in FIG. In this embodiment, an azimuth measuring unit 14 is provided in the radio wave emitting device instead of the detection receiving unit 8 to measure the arriving direction of the radio wave from the radio wave emitting source 1, and the transmission / reception switching circuit 9 identifies the radio wave emitting source based on the azimuth. Control to emit radio waves from the transmitter. As a result, it becomes possible for the assigned radio wave emitting device to identify the radio wave emission source and to accurately emit the radio wave to the plurality of radio wave emission sources.

Therefore, even when there are a plurality of radio wave sources using various radio waves, a plurality of radio wave emission devices can be separately allocated to emit radio waves, and the radio wave emission devices can be used effectively.
