Detailed Description
The invention is described in detail below by way of example with reference to the accompanying drawings.
The invention provides a method for generating main indexes of out-of-defense aviation communication countermeasure equipment, which is mainly used for scouting and interfering the command control communication of an enemy, disturbing the normal combat action of the enemy, reducing the overall combat efficiency and supporting the self to successfully achieve the aim of combat. The system is usually composed of two parts of equipment, namely communication counterreconnaissance and communication interference, and takes airplanes, unmanned planes, helicopters and the like as platforms. The method can be summarized into the steps of establishing a typical attack and defense combat scene, determining a combat effect judgment standard, developing a simulation experiment under multiple scenes, collecting and processing simulation case data, calculating fighting technical indexes of communication and determining the index requirements of a single set of equipment, and is shown in figure 1.
Firstly, a typical attack and defense battle scene is constructed. In view of the fact that an enemy attacking and preventing scene is far in communication distance of an enemy and close in interference distance of the enemy, the communication interference of the enemy has the advantage that the enemy can be interrupted without large interference power, and therefore the enemy attacking and preventing scene is selected as an analysis object. Under the command of an early warning command machine, a pre-positioned sweeping, air defense pressing, air assault and formation of out-of-defense area aviation communication countermeasure equipment form assault marshalling, and air assault is conducted on ground targets of enemies under the protection of communication interference. The enemy is a guard ground target, and under the command of the early warning command machine, the front-mounted interception of the fighter plane (air patrol waiting for war, airport waiting for war) and the rear-mounted defense situation of the ground-air missile weapon system are formed, and after the air attack action of the fighter plane and the ground-air missile weapon system are found, the fighter plane and the ground-air missile weapon system are commanded to carry out interception on the assault action.
The method is characterized in that the action range of an aerial communication countermeasure equipment position enemy ground-air missile weapon system outside a defense area of the I and the direct attack distance of an air fighter are out, reconnaissance and interference are carried out on communication between an enemy early warning command machine and an intercepting fighter of the enemy early warning command machine before the sudden-attack action is initiated until sudden-attack marshalling is separated from a dangerous area (the guidance of the enemy early warning command machine on the ground-air missile weapon system through a wireless communication system is not considered temporarily, the same is carried out below), and the intercepting fighter is guided to the air marshalling of the enemy command machine by the destroying command system, so that the safe air marshalling of the I is shielded and the sudden-attack task is completed smoothly. Before the sudden attack action is initiated, an enemy early warning command aircraft position is assumed to fly near a sudden attack route of the enemy and along a runway route which is basically vertical to the sudden attack direction of the enemy; a plurality of interception fighter teams are arranged in a patrol array position front-mounted and separated mode, and each team adopts a millstone tactic to keep the detection of an assigned airspace.
After the sudden attack action is found, the enemy early warning command machine guides the fighter plane to go out of the front for interception by utilizing the detected air situation command of the fighter plane. After the enemy interception fighter plane is interfered by communication of our party, the enemy interception fighter plane flies in a hovering mode according to a preset plan or flies along the direction of our plane mastered by the moment of communication interruption. The early warning command machine of our party commands I to prevent empty suppression and form an air assault to avoid flying according to the movement direction of the enemy intercepting fighter after being interfered, namely, the enemy is avoided to intercept the fighter to implement assault, and the fighter quickly returns after assault is finished. The enemy interception fighter plane can intercept the sudden defense and return aircraft under the condition of smooth communication and mastering the situation of the aircraft. After I suddenly attack marshalling and break away from the dangerous area and return to the air, the aviation communication countermeasure equipment outside the defense area stops interfering, and the interference shielding action is finished.
And secondly, defining the judgment standard of the battle effect. The anti-equipment for the aviation communication outside the defense area disturbs the command communication of the enemy, so that the command of the enemy fails and the force is out of control, thereby reducing the action effect of the fighting of the enemy and even paralyzing the fighting system of the enemy. In the defense-outburst combat, the interception action of the enemy to the defense-outburst airplane is mainly destroyed, and the defense-outburst airplane is shielded; in air defense combat, the combat action of an enemy aerovane is mainly destroyed, and the enemy aerovane is shielded from attacking enemy assault weapons. The method is a main mode for preventing the action of the other party in enemy air defense or penetration defense battles by guiding enemy attack weapons (intercepting airplanes or protecting airplanes) to the enemy attack weapons (protecting airplanes or intercepting airplanes), and the action aircrafts in the battles are guided to carry out the action by commanding the enemy attack weapons to depend on a wireless communication means. Therefore, communication interference which causes that an enemy early warning commander cannot intercept a fighter plane to a penetration plane in penetration and penetration fighting is called effective communication interference shielding.
And thirdly, carrying out a simulation experiment under multiple scenes. And (3) covering various conditions as much as possible, developing a simulation experiment by adopting an exploratory test method according to the simulation scene provided in the first step and the effective communication interference judgment standard set in the second step, and accumulating experimental data for providing the communication countermeasure combat requirement. Assuming that the battle boundary (the geographical boundary of the actual control range of two parties) of two parties of the enemy and the depth target of the enemy to be hit by the enemy are determined, the enemy constructs a defense system around the targets, and the scene elements can be changed in the following aspects: i, our party. The early warning director deploys array bits, such as front deployment and back deployment; the early warning director array bit is short or high, for example, the array bit is short or long, and the array bit is high or low; pre-sweep, anti-empty-hold, air-kick formation out time intervals, e.g., ranging from short to long intervals; the front-mounted sweeping, air defense suppressing and air assault formation attack direction has the same assault defense airway and two assault defense airways; under the condition of a plurality of sudden defense air routes, the air route interval is changed, such as the air route interval is different from small to large; deployment positions of communication countermeasure equipment outside a defense area, such as front deployment and back deployment; the communication countermeasure equipment outside the defense area has the length and the height of the array bits, for example, the length of the array bits is from short to long, and the height of the array bits is from high to low. ② enemies. The early warning director deploys array bits, such as front deployment and back deployment; the length and the height of the array position of the early warning director, for example, the length of the array position is from short to long, and the height of the array position is from high to low; intercepting the mode of the aircraft moving, such as completely adopting an airport to wait for war, completely adopting an airspace police patrol, partially adopting the airport to wait for war and partially adopting the airspace police patrol; arranging modes of airspace police patrol airplanes, such as arranging according to small intervals to large intervals; range of the ground-to-air missile weapon system, such as from short range, mid range to long range; and the ground-to-air missile weapon system is deployed at a position, such as front deployment and rear deployment. And combining the scene element changes to form a series of different scenes, and respectively carrying out simulation experiments.
And step four, collecting and processing simulation case data. Firstly, experimental data of each simulation case in the third step are collected. Aiming at the air defense suppressed airplane and the air assault airplane, scenes that the interception task cannot be finished due to improper force deployment of enemies under the non-interference condition are removed at each combat moment, and the interception task cannot be finished at each combat momentEfficient communication interference shieldingUnder the condition, the distance (recorded as communication distance R) between the enemy early warning commander and the interception fighter plane is collectedtDistance between both communication transceivers) and distance between communication countermeasure equipment outside the defense area and the enemy interception fighter plane (interference distance R for short)jDistance between communication jammer and communication receiver), distance between warning devices (abbreviated as R)z) And interference distance RjDistance R from communicationtThe ratio ρ (referred to as interference communication distance ratio, short for interference communication distance ratio); the included angle (multiplied by 2 and recorded as alpha) between the connecting line of the communication countermeasure equipment outside the defense area and the enemy interception fighter plane and the perpendicular line (pointing to one side of the control area of the enemy) of the flight direction of the communication countermeasure equipment outside the defense area is shown. Then, the ratio of the dry-passing distance ρ to the dry-passing distance RzAnd alpha are sorted, and the maximum value rho is respectively found outmax、Rzmax、αmax. They are the tactical target requirements for communication to resist reconnaissance interference by effective communication interference shielding.
And fifthly, calculating the fighting skill index of the communication countermeasure. In the case of free space radio wave propagation, the communication interference equation is:
in the formula (I), the compound is shown in the specification,
Kj: a suppression system for suppressing a ratio of interference signal power to communication signal power at an input of the communication receiver;
λ: a signal wavelength;
Pj: communication jammer output power;
Gjr: gain of the communication interference antenna in the direction of the communication receiving antenna;
Grj: gain of the communication receiving antenna in the direction of the communication interference antenna;
Rj: the distance between the communication jammer and the communication receiver, namely the interference distance;
n: a number of targets;
Ld: communication jammer efficiency (here a number greater than 1) at multi-target interference;
Lj: communication interference signal loss (bandwidth mismatch, polarization loss, here a number greater than 1);
Pt: a communication transmitter output power;
Gtr: gain of the communication transmitting antenna in the direction of the communication receiving antenna;
Grt: gain of the communication receiving antenna in the direction of the communication transmitting antenna;
Rt: the distance between the communication transmitter and the communication receiver, i.e., the communication distance.
Assuming that the communication transmitter and the communication receiver share the antenna and are omnidirectional antennas, equation 1 can be simplified as follows:
PjGjr＝KjPtGtrρ2NLdLj (2)
according to the formula, the equation establishes the relation between the effective radiation power of the communication jammer (namely the product of the output power of the communication jammer and the gain of the communication jammer antenna) and the interference suppression coefficient, the effective radiation power of the communication transmitter, the multi-target number, the efficiency of the communication jammer in multi-target interference and the loss of communication jamming signals, and under the condition that the communication jamming requirements rho, alpha and N and the parameters of enemy communication equipment are known, the effective radiation power P of the communication jammer can be calculatedjGjrAnd the required space coverage range is reached to reach the effective radiation power requirement of the given communication interference. The main term on the right side of equation 2 is discussed below:
interference suppression factor Kj. The value of which depends on the level of communication interference technology research.
The number of multi-targets N. I.e. the number of simultaneous interfering frequency points. The number of the enemy interception fighter plane formation, the type of the communication equipment loaded on each interception fighter plane and the use mode of the communication equipment are closely related. In the aspect of single machine, in order to ensure flexible and reliable communication, an enemy intercepting fighter plane is often provided with a plurality of sets of communication equipment working at different wave bands; the same band also sets voice and data link communication devices. In the formation aspect, one wave channel is used in the formation for cooperative communication of formation members, and different wave channels are used by the formation for communication with a command post. In the above scenario, when three intercepting teams are started, theoretically, at least 3 channels connected with the command are needed to be used simultaneously, 3 channels are used in cooperation with each other, and 3 channels are used for voice communication.
The total number of simultaneous interference frequency points can be calculated according to the total number of simultaneous channels and the number of simultaneous interference frequency points required by each channel. In frequency use, for fixed frequency communication, one frequency point is used for one channel; for a CDMA communication network, one channel corresponds to one frequency (set). For fixed frequency communication, the number of simultaneous interference channels is equal to the number of simultaneous interference frequency points. For frequency hopping communication, when suppression type interference is adopted, the number of interference points required to be simultaneously interfered in each channel is a part of the frequency set point number of the frequency hopping channel; when smart interference is adopted, the number of interference frequency points required for each channel is less than the number of frequency set frequency points corresponding to the channel.
LdEfficiency of communication jammers for multi-target interference, LjThe control level of power amplifier nonlinearity and component loss in the manufacture of the out-of-defense aviation communication countermeasure equipment is reflected for communication interference signal loss (bandwidth mismatch and polarization loss).
From this, the effective radiated power (in P) to the jammer can be determinedjGjrMaximum value of) and the requirements of interference spatial coverage (denoted by a), and the scout distance (denoted by R)zmaxThe time required for signal capture, sorting and interference preparation is considered, and a certain margin needs to be added on the basis of the value), and the requirement of reconnaissance airspace coverage (represented by alpha, the electromagnetic situation of a battlefield is considered to be mastered more comprehensively, and a certain margin needs to be added on the basis of the value) is considered. The indexes are aiming at all fighting communication countermeasures in one battleIt is proposed that if some equipment (such as ground equipment developed earlier) is arranged in the military, the existing equipment and the equipment to be researched are considered together, so that the existing equipment can contribute to the battle requirements, and the equipment to be researched is needed to be implemented. If the battle is carried out on the sea far away from the land, the battle can be carried out only by means of aviation equipment.
And sixthly, determining the index requirement of a single set of equipment. In order to make the out-of-defense aeronautical communication countermeasure equipment work near the best efficiency, the broadband interference is often divided into a plurality of frequency bands according to experience. And calculating the effective interference radiation power requirement of communication of each frequency band by using formula 1 or formula 2. And estimating the weight, the power consumption, the heat dissipation and the installation space of the interference machine of each frequency band according to the effective radiation power of communication interference and the requirement of interference airspace coverage, and estimating the weight, the power consumption, the heat dissipation and the installation space of the communication counterreconnaissance reconnaissance equipment according to the requirements of communication counterreconnaissance frequency bands, reconnaissance distances, reconnaissance airspace coverage, multi-target numbers and the like. The communication counterscout equipment and the interference machines in all frequency bands are accumulated in required weight, power consumption, heat dissipation and installation space, and if a single set of the aviation communication counterscout equipment outside the defense area can meet all loading requirements, one set of the aviation communication countercheck equipment is developed, so that the communication interference combat requirements can be met. If the bearing capacity of a single set of equipment is exceeded, the communication interference radiation power needs to be distributed to a plurality of sets of equipment, and at the moment, in order to reduce the number of establishment personnel, the combat capacity of the single set of equipment needs to be maximized, so that the total number of required communication countermeasure equipment outside a defense area is reduced as much as possible. Under the condition that a plurality of sets of defense area external communication countermeasure equipment are used simultaneously, modes of 'simultaneously suppressing the same wave band' and 'respectively suppressing the different frequency bands' can be adopted among the defense area external communication countermeasure equipment so as to meet the requirements of effective interference shielding on communication interference frequency domain, time domain, space domain and energy.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
