[0002] For short-time random dense group targets, most of the existing technical judgment methods are for independent target entities. For multi-directional group targets, the interception sequence is determined by locking according to the time when the group target is detected, resulting in poor interception efficiency. Therefore, how to effectively intercept multi-directional group targets has become a problem to be solved.

[0059] It should be understood that the specific embodiments described herein are merely intended to explain the present application and not to limit the present application.

[0060] Reference Figure 1 , Figure 1 The multi-azimuth air group target interception simulation device structure schematic diagram of the hardware running environment involved in the embodiment scheme of the present application.

The memory 1005 can also be an independent storage system from the aforementioned processor 1001.

[0062] Those skilled in the art can understand that Figure 1 The structure shown in the figure does not constitute a limitation on the multi-aspect aerial group target interception simulation device, and can include more or fewer components than the figure, or combine certain components, or different component arrangements.

[0063] As Figure 1 As shown, the memory 1005 as a storage medium can include an operating system, a network communication module, a user interface module, and a multi-aspect aerial group target interception simulation program.

[0064] In Figure 1 In the multi-aspect aerial group target interception simulation device shown in the figure, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the multi-aspect aerial group target interception simulation device of the application can be arranged in the multi-aspect aerial group target interception simulation device, and the multi-aspect aerial group target interception simulation device calls the multi-aspect aerial group target interception simulation program stored in the memory 1005 through the processor 1001, and executes the multi-aspect aerial group target interception simulation method provided by the embodiment of the application.

[0065] The embodiment of the application provides a multi-aspect aerial group target interception simulation method, which refers to Figure 2 , Figure 2 The flowchart of the first embodiment of the multi-aspect aerial group target interception simulation method of the application is shown.

[0066] The multi-directional air group target interception simulation method includes the following steps:

[0067] Step S10: When the multi-directional air group target is monitored by the interception platform, a conical radiation space region is formed by the radiation waves of the interception platform to cover each directional air group target, and the total threat degree corresponding to each directional air group target is calculated by a threat membership function.

[0068] It is easy to understand that the execution subject of the embodiment can be a multi-directional air group target interception simulation system with functions of data processing, network communication and program running, or other computer devices with similar functions, and the embodiment is not limited thereto.

[0069] In the embodiment, the multi-directional air group target interception simulation method includes the following steps: Figure 3 Figure 3 FIG. 1 is a coverage conical region diagram of the multi-directional air group target interception simulation method according to the first embodiment of the present application, the group target includes a horizontal formation, a vertical formation and a ring formation, and the reference unit parameters of different group target structures are assumed to be the same. It is assumed that the number of targets is n (n=5 in this example), which is composed of a central target and four targets in each of the four directions around the central target, and the distance between the central target and the surrounding targets is the same. The central target is numbered 1, the target in the forward direction is numbered 2, the target in the reverse direction is numbered 3, and the targets on the left and right are symmetrically numbered 4 and 5, as shown in FIG. 1. The interception platform is at point O, and the interception region is a conical region covering OAB. Figure 1

[0070] It should be noted that the platform radiates outwardly in a directional manner, the beam angle is fixed, and the angle formed by the beam center ray and the plane where the wave source is located is the inclination angle Under the constraints of the two angles, the final radiation wave forms a conical radiation space region, which can cause a killing effect on the targets in the region, as shown in FIG. 2. Figure 4 Figure 4 FIG. 3 is a distribution diagram of the platform radiation at the target distance according to the first embodiment of the multi-directional air group target interception simulation method of the present application.

[0071] In the embodiment, in order to cover each target in the group target by the radiation wave to form a conical radiation space region, the following conditions need to be met:

[0072] As shown in FIG. 4, Figure 5 Figure 5 ​​​​For the geometric relationship diagram of the radiation beam and the annular of the first embodiment of the multi-directional air group target interception simulation method of the present application, the annular is analyzed geometrically, the center line of the radiation beam (i.e. point A) is aimed at the No. 1 target, and within the height, it needs to meet that the five targets are kept within the beam range, and the following analysis and calculation are carried out:

[0073]

[0074]

[0075] In the formula, a is the semi-major axis length, which can generally guarantee the coverage of the target, b is constrained so as to meet That is, the formula needs to be met:

[0076]

[0077] It should also be noted that the energy transmission is subject to certain attenuation rules, for a certain target, the damage threshold is a constant value, and the corresponding target needs to cause the expected level of damage under the condition that the distance XX is a specific distance preset by the user.

[0078] Reference Figure 6 , Figure 6 For the geometric relationship diagram of the radiation beam and the V-shaped of the first embodiment of the multi-directional air group target interception simulation method of the present application, in addition to the annular, the V-shaped is also a common formation, and the geometric analysis is carried out in the same way. Since the distance between the No. 4 and No. 5 targets is the largest distance in the horizontal direction, the largest horizontal short axis b is used to constrain the conditions to ensure that the entire radiation beam is within the beam. At this time According to the geometric relationship, the distance from point B in the long axis direction to point A is longer than the length of the bottom line of the V-shaped, so as to ensure that the No. 4 and No. 5 targets meet the above formula, and at the same time, the No. 1, No. 2 and No. 3 targets are ensured to be within the radiation beam range.

[0079] It should also be understood that since the shapes of the group targets are different, the conditions to be met are different, and different shapes can be analyzed to adjust the radiation beam so that each target in the group target is within the radiation beam range.

[0080] Furthermore, the processing method for calculating the total threat degree corresponding to each direction air group target respectively through the threat membership function is as follows: determining the distance threat membership function, the speed threat membership function, the altitude threat membership function and the heading angle threat membership function according to the threat membership function; calculating the distance threat membership corresponding to each target in the multi-directional air group target respectively through the distance threat membership function; calculating the speed threat membership corresponding to each target in the multi-directional air group target respectively through the speed threat membership function; calculating the altitude threat membership corresponding to each target in the multi-directional air group target respectively through the altitude threat membership function; calculating the heading angle threat membership corresponding to each target in the multi-directional air group target respectively through the heading angle threat membership function; and obtaining the total threat degree corresponding to each direction air group target through the total threat degree calculation formula according to the distance threat membership, speed threat membership, altitude threat membership and heading angle threat membership corresponding to each target in the multi-directional air group target.

[0081] The distance threat membership function is:

[0082]

[0083] Where, is the distance threat membership corresponding to each target in the multi-directional air group target, k is the correction coefficient, D1 is the critical distance at which the threat reaches the maximum, D2 is the critical distance at which the threat disappears, r is the distance between each target and the interception platform, and k=0.1, D1=10km, D2=200km.

[0084] It should be noted that this function is used to quantify the distance between the target and the interception platform as a threat membership. When the distance is within a certain distance D1, the distance threat reaches its maximum. Conversely, beyond a certain distance D2, the threat disappears. At a certain distance in the middle, an exponential function is used to represent the attenuation of the threat level.

[0085] The speed threat membership function is:

[0086]

[0087] Where y(v) is the velocity threat membership corresponding to each target in the multi-directional aerial group target, v is the moving speed of each target, and k is the correction coefficient, which is set to 2.

[0088] It should be understood that this function represents the target threat membership at different speeds, and the faster the speed, the higher the threat level.

[0089] The high threat membership function is:

[0090]

[0091] Where, h is the height of each target corresponding to the ground, h = 0.1, k = 0.5. r h is the height of each target corresponding to the ground, h = 0.1, k = 0.5. r h is the height of each target corresponding to the ground, h = 0.1, k = 0.5.

[0092] It is to be noted that the function represents the relationship between the threat degree and the height, when the height is lower than a certain value a, it is difficult to find the target and then difficult to intercept, and the threat is the largest; the higher the height, the easier to be found and tracked and aimed, and the threat degree gradually decreases.

[0093] The heading angle threat membership function is:

[0094]

[0095] In the formula, h is the heading angle threat membership degree of each target in the multi-direction air group target, k is a correction coefficient, k = 1, is the heading angle of each target. In the specific implementation, the heading angle of the target is analyzed and calculated by using the function, and the approaching speed of the target can be obtained according to the heading angle, which is relative to the speed of the target itself, the greater the absolute value of the angle, the smaller the threat degree, and when the heading angle is

[0096] , the threat of the target is the largest.

[0097] Further, the threat membership degrees calculated by the previous functions are accumulated to obtain the total threat degree of the target after considering several important indexes, and the objects are all the same target, so the calculation formula of the total threat degree is:

[0098]

[0099] In the embodiment, it is assumed that a situation is composed of five targets, and the group target is in a ring shape and attacks. It is assumed that the group center target of the attacking target is 40 km away from the platform, the heading angle , the distance between each target is 1 km, the flight height of all targets is 0.2 km, and the flight speed is 0.7 Ma.

[0100] According to the threat membership degree function, the following is calculated:

[0101]

[0102]

[0103]

[0104] ​

[0105]

[0106] At the same time, the reaction time is calculated according to the distance and the speed:

[0107]

[0108] Therefore, for different targets in the same, the threat degree is equivalent. Continue to analyze the motion parameters of the whole.

[0109] If the target speed in the situation is faster, reaching 0.9Ma, the total threat is calculated as , which is higher than before, and the reaction time is reduced to , which is consistent with the conclusion that the faster the target speed, the higher the threat degree. Further analysis of the distance, if the target distance is found to be reduced to 20km in the situation, the total threat is calculated as , the reaction time is also shortened, at this time , the total threat degree is improved more obviously.

[0110] Step S20: selecting the maximum threat degree and the second threat degree from the total threat degrees corresponding to the multiple air group targets, and taking the air group target corresponding to the maximum threat degree as the first batch of group targets, and taking the air group target corresponding to the second threat degree as the second batch of group targets.

[0111] In this embodiment, the group targets may attack from two directions or multiple waves. Multiple wave attacks may also be a group integrated by multiple targets in each wave, and the actual situation that may occur is very complex. Next, a simple case is taken as an example for illustration:

[0112] If there are a batch of attacking group targets in the left and right directions, the priority of intercepting targets, platform turning time and other factors need to be considered, and the priority of intercepting multiple azimuth targets needs to be selected, which needs to be analyzed in terms of threat and distance turning time.

[0113] Step S30: determining the first remaining turning time of the first batch of group targets to the second batch of group targets, and determining the second remaining turning time of the second batch of group targets to the first batch of group targets.

[0114] In this embodiment, reference is made to Figure 7 , Figure 7 is a situation diagram of two group targets of the first embodiment of the multi-azimuth air group target interception simulation method of the application, assuming that a batch of group targets attack from the left , five targets form a ring, approach at a speed of 0.7Ma, heading angle, 1km height, 10km away from the platform when discovered, and a batch of group targets attack from the right Another batch of targets is coming, five targets form a V shape, with a speed of 0.9Ma, The heading angle is 1km height close to the platform, 12km away from the platform when discovered.

[0115] The platform turns fire time is v z =20° / s, the damage time t d of the target at different distances meets:

[0116]

[0117] The left is the first batch of targets, and the right is the second batch of targets. After calculation, the threat degree of the first batch of targets is W1=13.5, and the threat degree of the second batch of targets is W2=12.8. At this time, the first batch of group targets should be intercepted first, and then the second batch of group targets should be intercepted.

[0118] If the speed parameter is adjusted from 0.9Ma to 1.2Ma, in this case, after considering the direct threat degree of the two batches of targets, further analysis is carried out considering the actual situation of interception time and turning fire time, at this time the threat degree of the second batch of group targets changes, at this time the time remaining formula is:

[0119]

[0120] In the formula, is the remaining steering time, is the arrival time of steering the ith batch of group targets, is the time of intercepting the ith batch of j group targets, is the turning fire time.

[0121] Here we set a threshold, which is the time needed to successfully intercept the target, which is the safety time t s =10s needed to intercept the close-range batch of targets, if t m <t s , it is considered that there is no enough safety guarantee to complete the interception of the batch of targets, and a new interception scheme needs to be analyzed.

[0122] Through the analysis of this scenario, W1=13.5 and W2=13.2 are obtained, and the threshold condition is analyzed and judged, and the calculation is:

[0123]

[0124]

[0125]

[0126] The remaining interception time is:

[0127]

[0128] This interception plan cannot guarantee the successful interception of two batches of group targets, which will threaten the platform. The interception plan needs to be reconsidered, and the second batch of targets with lower threat level should be intercepted first. The time of each plan is calculated as follows:

[0129]

[0130]

[0131]

[0132] The remaining interception time at this time is:

[0133]

[0134] The analysis results show that the second solution is better, ensuring the successful interception of two batches of group targets without threatening the platform.

[0135] Step S40: determining the power density value of each target in the first group of targets and the power density value of each target in the second group of targets through spatial geometric relationships.

[0136] In a specific implementation, it is also necessary to determine the power density value of each target in the first group of targets and the power density value of each target in the second group of targets.

[0137] Without considering atmospheric attenuation, the radiation power will not decay, but as the distance increases, the radiation area increases and the power density decreases accordingly. Because radiation is a cone with the radiation source as the vertex, the area at different distances satisfies the formula:

[0138]

[0139] In fact, atmospheric attenuation is an important factor that cannot be ignored. For example, under common clear weather conditions, the radiation power attenuation can be To perform exponential decay fitting, the power density calculation formula is:

[0140]

[0141] Where S is the power density at the target distance, P is the radiation power of the radiation source, G is the directional radiation antenna gain, and R is the distance between the radiation source and the target.

[0142] P and G are both known data, but R is not directly known and needs to be calculated based on the known data. In target information acquisition, the horizontal distance r between the target and the platform and the target's flight altitude h are known. The calculation formula for R is:

[0143]

[0144] And the inclination is obtained by Beam angle depends on the characteristics of the platform itself, and the radiation directionality coefficient of the beam edge is half of the beam center.

[0145] Reference Figure 4 It can be known that according to the spatial geometric relationship:

[0146]

[0147]

[0148]

[0149]

[0150] In the formula, S A is the power density value of A target in the group target, S B is the power density value of B target in the group target, S C is the power density value of C target in the group target, S D is the power density value of D target in the group target, and S E is the power density value of E target in the group target.

[0151] Step S50: According to the first remaining steering time length, the second remaining steering time length, the power density value of each target in the first batch of group targets and the power density value of each target in the second batch of group targets, the first batch of group targets and the second batch of group targets are intercepted respectively. Simulation.

[0152] It should be understood that, Figure 4 In the formula, R is the distance between targets. After comparing and analyzing several parameters, it can be known that the power density of S A is the largest, and the power density of S C is the smallest. Comparing S C with the expected performance level power density, if it is greater than the minimum value, it can cause all targets in the region to be damaged above the expected level, if it cannot be satisfied, S A is compared with the expected damage performance level power density. If it is lower than the maximum value, all targets in the region cannot cause the expected damage.

[0153] Further, the minimum power density value of the first batch of group targets is determined according to the power density values of the targets in the first batch of group targets, and the minimum power density value of the second batch of group targets is determined according to the power density values of the targets in the second batch of group targets; it is judged whether the expected performance level power density value is greater than the minimum power density value of the first batch of group targets and / or the minimum power density value of the second batch of group targets, and whether the first remaining steering time and / or the second remaining steering time is greater than the preset safe interception time; if the expected performance level power density value is greater than the minimum power density value of the first batch of group targets and the minimum power density value of the second batch of group targets, and the first remaining steering time and the second remaining steering time are greater than the preset safe interception time, the first batch of group targets can be intercepted according to the size of the threat degree, and after the interception is completed (i.e. the accumulated radiation energy of each target in the first batch of group targets reaches the corresponding damage threshold of each target), the interception platform is controlled to turn to the second batch of group targets for interception.

[0154] It should be understood that after intercepting the first batch of group targets and the second batch of group targets, the step of selecting the maximum threat degree and the second threat degree from the total threat degrees of the multi-aspect aerial group targets is needed, and the first batch of group targets and the second batch of group targets are re-determined for platform turning.

[0155] It should be further explained that if the expected performance level power density value is greater than the minimum power density value of the group targets, it means that the damage threshold can be reached at the minimum position of the radiation energy, and each target in the batch of group targets can be damaged. Assuming that the minimum position of the radiation energy of the target in the first batch of group targets cannot reach the damage threshold, part of the targets in the first batch of group targets need to be damaged to reach the damage threshold, and then the total threat degrees of the remaining targets in the first batch of group targets and the total threat degrees of the other group targets are calculated in real time, and the batch of group targets and the remaining steering time are re-determined, so as to determine whether to turn and intercept or wait according to the power density value and the remaining steering time.

[0156] It should be further understood that for the same type and size of target, the damage threshold is a fixed estimated value. When the target is of different types, the damage threshold will change, but it is still a fixed estimated value. When the target type (shape size, component, protection level) is different, its damage threshold is different, but the damage threshold of the same type target is the same.

[0157] If the expected performance level power density value is greater than the minimum power density value of the first batch of group targets and the minimum power density value of the second batch of group targets, and the first remaining steering duration is less than or equal to the preset safe interception duration, and the second remaining steering duration is greater than the preset safe interception duration, in order to effectively intercept the multi-azimuth group target, the second batch of group targets needs to be intercepted, and after the interception is completed (that is, the accumulated radiation energy of each target in the second batch of group targets reaches the damage threshold), the interception platform is controlled to turn to the first batch of group targets for interception.

[0158] In the embodiment, when the interception platform monitors the multi-azimuth air group target, first, the total threat degree corresponding to each azimuth air group target is calculated by a threat membership function, then the maximum threat degree and the second threat degree are selected from the total threat degrees corresponding to the multi-azimuth air group target, the air group target corresponding to the maximum threat degree is taken as the first batch of group targets, and the air group target corresponding to the second threat degree is taken as the second batch of group targets, then the first remaining steering duration of the first batch of group targets to the second batch of group targets is determined, and the second remaining steering duration of the second batch of group targets to the first batch of group targets is determined, finally, the power density values of the targets in the first batch of group targets and the power density values of the targets in the second batch of group targets are determined through spatial geometric relationship, and the first batch of group targets and the second batch of group targets are intercepted respectively according to the first remaining steering duration, the second remaining steering duration, the power density values of the targets in the first batch of group targets and the power density values of the targets in the second batch of group targets. In the embodiment, the interception simulation scheme is formulated through the total threat degree and the steering duration in the radiation space region, and the effective interception of the multi-azimuth group target is realized.

[0166] In this embodiment, when the interception platform monitors multi-azimuth air group targets, first, the total threat degrees corresponding to the multi-azimuth air group targets are calculated respectively through a threat membership function, then the maximum threat degree and the second threat degree are selected from the total threat degrees corresponding to the multi-azimuth air group targets, the air group target corresponding to the maximum threat degree is taken as the first batch of group targets, the air group target corresponding to the second threat degree is taken as the second batch of group targets, then the first remaining turning time for the first batch of group targets to perform platform turning towards the second batch of group targets is determined, the second remaining turning time for the second batch of group targets to perform platform turning towards the first batch of group targets is determined, finally, the power density values of the targets in the first batch of group targets and the power density values of the targets in the second batch of group targets are determined through spatial geometric relations, and the first batch of group targets and the second batch of group targets are subjected to interception simulation respectively according to the first remaining turning time, the second remaining turning time, the power density values of the targets in the first batch of group targets and the power density values of the targets in the second batch of group targets.
