[0127] Embodiment 2

[0128] See also Figure 2 , Figure 1 : is a flow chart of another terminal defense data processing method disclosed in an embodiment of the present invention. Figure 2 The described terminal defense data processing method is applied to the field of defense command and control technology, and is not limited in the embodiments of the present invention.

[0129] 1. Cellular grid division of digital maps

[0130] In the automatic optimization deployment calculation, in order to quantify the optimization search interval and provide support for subsequent template deployment and adjustment, the defense area is divided into hexagonal honeycomb grids centered on the defense target. Considering factors such as the combat radius of the terminal defense equipment and the amount of optimization calculation, the equipment is mainly deployed within 35km around the defense target. The default spacing between adjacent grid centers is 1km, and it can be adjusted by the user according to evaluation needs. The schematic diagram of honeycomb grid division of the defense target is shown in the figure below. Figure 3 shown.

[0131] 2. Template deployment of terminal defense equipment

[0132] The deployment templates of terminal defense equipment can generally be divided into four types: ring deployment, fan deployment, linear deployment and triangular deployment.

[0133] 2.1 Ring deployment template

[0134] Ring deployment is mainly used for the deployment of terminal defense equipment when the attack direction of the target is unknown (i.e. omnidirectional) or the attack angle range is too large (default is greater than or equal to 300 degrees). The schematic diagram is as follows Figure 4 As shown. In the ring deployment method, each defense equipment is deployed at equal intervals on a circle centered on the defense target (the specific position can be adjusted according to the terrain characteristics and the deployable rules according to the adjacent cells), and the radius of the circle depends on the number of defense equipment, the firepower range, and the firepower overlap range. The default optimization adjustment method for ring deployment is: according to the number of defense equipment and the firepower range parameters of the defense equipment input by the user, the firepower overlap range is adjusted, thereby affecting the radius of the circle, and then the radius + angle combination is traversed and calculated to obtain all ring deployment plans.

[0135] 2.2 Fan-Shaped Deployment Template

[0136] Sector deployment is mainly used for the deployment of terminal defense equipment when the attack direction (i.e., the attack angle range) of the attack target is known (less than 300 degrees by default). The schematic diagram is as follows Figure 5 As shown. In the fan-shaped deployment method, each defense equipment is deployed at equal intervals on a fan-shaped arc centered on the defense target (the specific position can be adjusted according to the terrain characteristics and the deployable rules according to the adjacent cells). The interception start and end positions of the fan (depending on the coverage of the edge defense equipment fire area to the border, which is the same as the fire overlap range between the two defense equipment fire areas by default) are consistent with the attack target's attack angle range. The radius of the fan depends on the number of defense equipment, fire range and fire overlap range. The default optimization adjustment method for fan-shaped deployment is: according to the number of defense equipment and the fire range parameters of the defense equipment input by the user, the fire overlap range is adjusted, thereby affecting the radius of the fan. There is only one deployment plan under each determined radius.

[0137] 2.3 Linear Deployment Template

[0138] Linear deployment is mainly used for the deployment of terminal defense equipment when the attack direction (i.e., the attack angle range) of the attack target is known (less than 180 degrees by default). The schematic diagram is as follows: Figure 6 As shown. In the linear deployment method, each defense equipment is deployed at equal intervals on a line segment covering the incoming direction (the specific position can be adjusted according to the terrain characteristics and the deployable rules according to the adjacent cells). The interception start and end positions of the line segment (depending on the coverage of the edge defense equipment fire area to the boundary, which is the same as the fire overlap range between the two defense equipment fire areas by default) are the same as the attack target's incoming angle range, and the line segment length depends on the number of defense equipment, fire range, and fire overlap range. The default optimization adjustment method for linear deployment is: according to the number of defense equipment and the fire range parameters of the defense equipment input by the user, the fire overlap range is adjusted, thereby affecting the length of the line segment (as well as the vertical distance from the defended target to the line segment). There is only one deployment plan for each determined line segment length.

[0139] 2.4 Triangle deployment template

[0140] Triangle deployment is mainly used for the deployment of terminal defense equipment under the conditions that the attack direction of the target (i.e. the attack angle range) is less than or equal to 120 degrees and the number of defense equipment is greater than or equal to 3. It is suitable for dealing with the enemy's saturation attack. The schematic diagram is as follows Figure 7 As shown. In the triangle deployment method, more than three terminal defense equipment form an equilateral triangle that is continuous horizontally relative to the attack direction of the attack target. The side length of the triangle depends on the overlapping range of firepower. The angle bisector of the attack angle of the attack target is perpendicular to one side of the triangle and bisects the entire defense formation. The interception starting position and interception ending position of the entire defense formation are the same as the attack angle of the attack target. The default optimization adjustment method for triangle deployment is: according to the number of defense equipment and the firepower range parameters of the defense equipment input by the user, the overlapping range of firepower is adjusted, thereby affecting the side length of the equilateral triangle. According to the vertex orientation of the equilateral triangle, there are two deployment schemes for each determined side length.

[0141] 3. Principles for optimizing deployment of terminal defense equipment

[0142] To optimize the deployment of terminal defense equipment, some basic principles must be followed. Through the analysis of the deployment of terminal defense equipment, in order to ensure the rationality of the optimized deployment plan, the optimized deployment of terminal defense equipment should follow the principles of reasonable deployment interval, coverage of the incoming direction, avoidance of existing firepower, availability of deployment area, fault tolerance of plan fine-tuning, and controllable calculation time.

[0143] (1) Deployment area availability

[0144] The availability of the deployment area means that the selected deployment location of the terminal defense equipment is actually available. For example, a certain defense deployment deploys equipment in a certain honeycomb grid, and the area corresponding to this honeycomb grid happens to be a lake, so the equipment cannot be deployed at all, which means that the deployment area is unavailable. To check whether the deployment area is available, it is necessary to make a comprehensive judgment based on the topography, surface elevation, and appropriate map information of the defense area.

[0145] (2) Reasonable deployment interval

[0146] The terminal defense equipment optimization deployment method is based on the cellular grid, so the deployment interval here is first of all a question of cellular grid size division, and the size of the cellular grid division directly affects the effect of the optimized deployment. A larger grid has a smaller amount of calculation, but the result is not fine enough; a smaller grid has a higher deployment position accuracy, but the amount of calculation is large. Therefore, the selected cellular grid size should be a compromise between the amount of calculation and the deployment position accuracy.

[0147] In addition, for the deployment methods of circular deployment, fan deployment, linear deployment and triangular deployment, the distance between two defensive equipment should be calculated according to their fire coverage range. If the distance is too large, a fire coverage blind spot may easily appear. If the distance is too small, the fire density in the overlapping area will be too high, resulting in insufficient coverage.

[0148] (3) Reasonable deployment method selection

[0149] The terminal defense equipment protects point targets. When the enemy attacks a point target, the attack direction is generally fixed and can be described by an azimuth sector. If the target attack direction is not fixed, its azimuth is omnidirectional. The available deployment methods corresponding to different attack ranges are shown in the following table.

[0150] Table of available deployment methods corresponding to the attack range

[0151]

[0152] (4) Existing firepower avoidance

[0153] Existing firepower avoidance means that when optimizing the deployment of terminal defense equipment, other defense firepower units that have been deployed in the area must be taken into consideration, and deployment in firepower areas close to defense firepower units must be avoided (for example, for already deployed medium- and long-range surface-to-air missiles, by default, they cannot be deployed in firepower areas within 30 kilometers of their missile positions) to avoid blocking of the firing range.

[0154] (5) Solution fine-tuning and fault tolerance

[0155] According to the deployment plans obtained by ring deployment, fan deployment, linear deployment and triangle deployment, a certain deployment grid may not be suitable for deployment. At this time, fine-tuning fault tolerance processing is required, such as considering whether the other six grids around this grid are suitable for deployment. If one is suitable, it can also be included in the scope of reasonable deployment for comprehensive consideration. Otherwise, deployment may not be possible in some special areas.

[0156] (6) Computation time is controllable

[0157] Time controllability means that the total computing time can be estimated and controlled when optimizing deployment. If it takes several days to perform a deployment calculation, it means that the algorithm is unreasonable. Therefore, it is necessary to estimate the calculation time before calculation. In order to shorten the calculation time during the calculation process, it is possible to consider sacrificing some optimization links to obtain a suboptimal deployment solution to ensure that the system can output the best solution obtained by the current calculation.

[0158] like Figure 2 As shown, the terminal defense equipment deployment method may include the following operations:

[0159] In view of the problem of terminal defense equipment deployment, this embodiment adopts a cellular template-based automatic optimization deployment method, and its overall idea is: first, optimize the deployment initialization, and input the location of the defense target, the size of the cellular grid, the direction and number of the incoming target, the number and deployment of existing defense units, the firepower range and number of terminal defense equipment, the topography of the defense area, and the prohibited / avoided deployment area through the human-computer interaction interface; then, according to the principle of availability of the deployment area and the avoidance of existing firepower, select the cellular grid for terminal defense equipment deployment from the defense area, and analyze the ring deployment, based on the firepower range and number of the terminal defense equipment. The deployment intervals of fan-shaped deployment, linear deployment, and triangular deployment are combined with deployable honeycomb grids to calculate the number of deployment plans corresponding to each deployment method. The total time for optimization calculation can be estimated based on the calculation time of the effectiveness evaluation of each deployment plan. For each deployment plan, the effectiveness evaluation module is called to calculate its corresponding combat effectiveness, and some deployment plans with higher combat effectiveness are extracted as the optimal set of deployment plans. Finally, by changing the incoming target route, the effectiveness of these deployment plans is calculated multiple times, and the effectiveness of each plan is added up, and finally a list of deployment plans sorted by effectiveness is output. The overall process of terminal defense equipment deployment is as follows: Figure 2 shown.

[0160] (1) Map data preprocessing: divide a certain range of the surrounding area of ​​the defense target into honeycomb grids with regular hexagons as the basic units, and automatically preprocess each honeycomb grid according to the rules to determine whether it is suitable for deploying weapons and equipment. The preprocessing results can be displayed based on the two-dimensional map and modified by the user;

[0161] (2) Automatic generation of deployment plans: Based on the map data preprocessing results, the existing defense unit deployment information, and the given attack target direction, a deployment plan for all terminal defense equipment is generated according to several customized deployment templates and corresponding rules;

[0162] (3) Automatic generation of attack plans: Based on the given attack direction, target type, number of targets, and combat rules, multiple attack plans are randomly generated for backup. The specific number of generated plans can be specified by the user.

[0163] (4) Deployment plan evaluation and ranking: randomly select an attack target attack plan, evaluate the combat effectiveness of all terminal defense equipment deployment plans, and rank all terminal defense equipment deployment plans according to the evaluation results;

[0164] (5) Optimize and sort the deployment plans. Traverse other attack target attack plans, evaluate and calculate the combat effectiveness of multiple plans ranked at the top in the current terminal defense equipment deployment plan list (the specific number can be selected in proportion or determined by the user), and sort the selected terminal defense equipment deployment plans according to the combat effectiveness under all attack target attack plans, thereby obtaining multiple terminal defense equipment optimized deployment plans ranked by effectiveness.

[0165] 1) Map data preprocessing process

[0166] Map data preprocessing is mainly to conduct availability analysis of cellular grid deployment areas, to judge and mark whether the geographical area corresponding to each cellular grid is suitable for deploying terminal defense equipment, and to provide support for the subsequent automatic generation of deployment plans. The deployment of terminal defense equipment needs to meet certain conditions, such as road accessibility, not being in water, prohibited / avoided deployment areas (such as towns, villages, etc.), and terrain undulations cannot be too large. The availability of the cellular grid deployment area is determined by checking whether the cellular grids (the default reference point is the cellular center point and 6 vertices) meet these constraints one by one. The cellular grid deployment area availability analysis process is as follows: Figure 8 shown.

[0167] All the output cell grid sets can be displayed on a two-dimensional map, and can be manually adjusted by the user and then stored in the database for future use. Fig. 9 After the availability analysis, each cell in the returned cell set has only two states: available and unavailable. Fig. 9 Green grids represent those that meet the requirements and can be deployed, while red grids are the opposite. On this basis, human intervention can be performed to change the availability status of certain specific grids. Finally, all grid information is stored for automatic generation of deployment plans later.

[0168] 2) Automatic generation of solutions

[0169] The reasonable deployment method is selected mainly according to the attack angle range of the enemy's attack target, a deployment plan collection is generated based on all available cellular grids, and the estimated time for optimization calculation is given. The deployment plan generation process is as follows: Fig.10 .

[0170] a. Automatic generation calculation method for linear deployment scheme

[0171] In linear deployment, the deployment positions of the defensive equipment are in a straight line with the same interval. The linear deployment interval is as follows: Fig.11 Show. Fig.11 In the figure, O is the target to be defended, AOB is the direction of the target attack, D1, D2, D3, and D4 are the center points of the defense equipment, R is the fire radius of the defense unit, L is the straight-line distance between the defense target and the line, and K is the depth overlap distance of the fire range of the two defense equipment. To ensure a certain degree of coverage overlap, the automatic adjustment range of K is 0.5R≤K≤2R, and the minimum adjustment interval of K is the honeycomb center distance. The automatic adjustment of K affects the length of the entire line segment D1D4 and the length of L, thus forming multiple deployment schemes. It should be noted here that in linear deployment, the line connecting the center points of the defense equipment D1D4 should be perpendicular to the center line OC of the attack direction to ensure the symmetry of the defense. If D1D4 is not perpendicular to OC, there will inevitably be a situation where the defense is weak at one end. Considering fault tolerance, the center of each defense unit can be offset within a certain range (the default is 1 honeycomb grid).

[0172] b. Automatic generation calculation method of ring deployment scheme

[0173] In the case of circular deployment, the deployment position of the defense equipment is on a circle. This deployment is generally used for the situation where the target is attacking from all directions. It is not suitable for the situation where the target is attacking from a direction and the angle range is small. Fig.12 shown. Fig.12 In the formula, O is the target to be defended, AOB is the direction of the target attack, D1, D2, ..., DN are the center points of the defense equipment, R is the fire radius of the defense unit, L is the circular deployment radius, and K is the depth overlap distance of the fire range of the two defense equipment. To ensure a certain coverage overlap, the automatic adjustment range of K is 0.5R≤K≤2R, and the minimum adjustment interval of K is the cell center distance. The automatic adjustment of K affects the length of the circular deployment radius L, and combined with the rotation (the minimum angle of the circle rotation is the angle between the cell center distance and the center of the circle O), multiple deployment plans can be formed. Conversely, when the distance between D1 and D2 is 1.732R, in order to ensure that there is no blind spot in the defense, the relationship between the circular deployment radius L and the required number of defense equipment can be calculated as shown in the following formula:

[0174]

[0175] Where ceil() means rounding up.

[0176] c. Calculation method for automatic generation of fan-shaped deployment scheme

[0177] In the case of fan-shaped deployment, the deployment position of the defense equipment is on a fan ring. This deployment is generally used for situations where the target is attacking in a directional manner. It is not suitable to use a ring deployment when the target is attacking in an omnidirectional manner. Fig.13 shown.

[0178] Fig.13 In the formula, O is the target to be defended, AOB is the direction of the target attack, D1, D2, ..., DN are the center points of the defense equipment, R is the fire radius of the defense unit, L is the fan deployment radius, and K is the depth overlap distance of the fire range of the two defense equipment. To ensure a certain coverage overlap, the automatic adjustment range of K is 0.5R≤K≤2R, and the minimum adjustment interval of K is the cell center distance. The automatic adjustment of K affects the length of the fan deployment radius L, thereby forming multiple deployment plans. Conversely, when the D2D3 distance is 1.732R, in order to ensure that there is no blind spot in the defense, the relationship between the fan deployment radius L and the required number of defense equipment can be calculated as shown in the following formula:

[0179]

[0180] Where ceil() means rounding up.

[0181] d. Automatic generation calculation method of triangle deployment plan

[0182] In the case of triangular deployment, the deployment position of the defense equipment is in an approximately equilateral triangle. This deployment is mainly aimed at the situation where the target is small-angle, high-density and directional, and the number of defense equipment is more than 3. Fig.14 shown.

[0183] Fig.14 In the figure, O is the target to be defended, AOB is the direction of the target attack, D1, D2, ..., DN are the center points of the defense equipment, R is the fire radius of the defense unit, L is the distance (or vertical distance) from the target to the nearest fire unit, and K is the depth overlap distance of the fire ranges of the two defense equipment. To ensure a certain coverage overlap, the automatic adjustment range of K is 0.5R≤K≤2R, and the minimum adjustment interval of K is the cell center distance. The automatic adjustment of K affects the side length of the triangle and the length of L, thus forming multiple deployment schemes.

[0184] 3) Automatic generation of incoming attack plans

[0185] For terminal defense equipment, the terminal overhead trajectory of all attack targets can be considered as a straight line, but different attack targets have different terminal profile trajectories, so the automatic generation of the attack plan mainly includes two parts: automatic generation of the target's terminal overhead trajectory and automatic generation of the terminal profile trajectory.

[0186] a. Automatic generation method of the target terminal downward trajectory

[0187] The automatic generation of the target terminal overlooking trajectory mainly depends on the direction and number of the target attack, which is divided into two types: omnidirectional target attack and directional target attack.

[0188] (1) Calculation method of terminal downward trajectory of omnidirectional incoming targets

[0189] When the targets are attacking from all directions, their attack directions are not fixed and can be evenly distributed or randomly distributed according to the number of attacking targets. The schematic diagram is as follows Fig.15 shown.

[0190] Assume that the number of targets is M. When generating the trajectory from the top of the target, random distribution or uniform distribution can be used. When randomly distributed, for each target, a direction is randomly generated in the range of [0,2π] as the attack route of the target; when uniformly distributed, the attack route of each target is generated at an angle interval of 2π / M, where the first target direction can be randomly generated in the range of [0,2π / M], the second target direction can be randomly generated in the range of [2π / M,4π / M], and so on.

[0191] (2) Calculation method of terminal downward trajectory of directional incoming target

[0192] When the target is directed at you, its direction is relatively fixed. The approximate terminal trajectory can be calculated based on the direction and number of the target. The schematic diagram is as follows: Fig.16 As shown. Where O is the defended target, and AOB is the possible attack direction of the target. Let the number of targets be M. When the target end is viewed from above, random distribution or uniform distribution can be used. When randomly distributed, for each target, a direction is randomly generated within the range of azimuth AOB as the attack route of the target; when uniformly distributed, the attack route of each target is generated with AOB / M as the angle interval. Let OA be the lower boundary angle of azimuth. Then the direction of the first target can be randomly selected within the range of [OA, OA+AOB / M], and the direction of the second target can be randomly selected within the range of [OA+AOB / M, OA+2AOB / M], and so on.

[0193] b. Automatic generation method of target terminal profile trajectory

[0194] The current terminal defense targets are mainly composed of four types of weapons: cruise missiles, precision-guided bombs, ballistic missiles and aerial bombs. Due to their different motion characteristics, the generated profile trajectories are also different. The classification is briefly described as follows:

[0195] ① Automatic generation of cruise missile terminal profile trajectory

[0196] The cruise missile usually cruises at a fixed relative ground altitude during the cruise phase. It will rise when it is 5 to 10 kilometers away from the target. After reaching a certain altitude, it will fly in a nearly straight line toward the target until it reaches the target point. The terminal motion profile is shown above. Fig.17 shown.

[0197] ②Automatic generation of terminal profile trajectory of precision-guided bombs

[0198] Under the guidance of the guidance module, the precision-guided bomb will constantly correct its flight path with reference to the target point during flight, and its trajectory is almost a straight line during the terminal attack. Fig.18 shown.

[0199] ③ Automatic generation of ballistic missile terminal profile trajectory

[0200] After the active phase ends, the ballistic missile enters the passive phase and flies along a free parabola trajectory. The passive phase is divided into a free flight phase and a reentry phase. When entering the terminal defense range, it generally enters the reentry phase, flies along a predetermined trajectory, and attacks fixed targets on the ground. The terminal motion profile is shown above. Fig.19 shown.

[0201] ④Automatic generation of terminal profile trajectory of aerial bomb

[0202] After the aerial bomb is dropped from the carrier aircraft at a certain initial velocity, the sum of the carrier aircraft speed and the ejection speed is taken as the initial velocity. Under the combined effect of gravity and air resistance, it performs a parabolic falling motion until it touches the ground. The terminal motion profile is shown above. Fig. 20 shown.

[0203] 4) Deployment plan evaluation and ranking

[0204] The main function of the deployment plan evaluation and sorting module is to calculate the combat effectiveness of each existing deployment plan according to a certain incoming plan randomly generated by the incoming plan automatic generation module, extract the top N (can be input externally) with the highest combat effectiveness and sort them for output. The output results can provide input for subsequent optimization sorting. The basic process of evaluation and sorting is as follows: Fig.21 shown.

[0205] 5) Deployment plan optimization and sorting

[0206] The main function of the deployment plan optimization and sorting module is to further optimize and sort the N groups of deployment plans that have been screened by the evaluation and sorting module according to their combat effectiveness. The main principle is to calculate the effectiveness of the N groups of deployment plans according to a large number of randomly generated different attack plans, accumulate the combat effectiveness values, and use large-scale random sampling to reduce errors, and finally obtain a relatively stable and reliable deployment plan sorting. The optimization sorting process is as follows: Fig. 22 shown.

[0207] The optimized sorting function is equivalent to a large number of repeated evaluation sorts (each time the incoming plan is different), and the calculation results of each time are superimposed and output, and accumulated until the sorting remains relatively stable or meets certain conditions, thereby ensuring the reliability of the current output.
