[0003] The traditional sense of weapon equipment system combat effectiveness evaluation is to measure the effectiveness of the weapon equipment system in achieving the expected goal under specific conditions.

Obviously, the described embodiments are only part of the embodiments of the present specification, not all the embodiments. Based on one or more embodiments of the present specification, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present invention.

[0034] The present invention will be described in detail below in combination with the specific embodiments and the drawings of the specification.

[0035] Method embodiments

[0036] According to the embodiments of the present invention, a combat effectiveness evaluation method based on a spatial information system is provided, as shown in Figure 1 and Figure 2 A combat effectiveness evaluation method based on a spatial information system provided for the present embodiment is shown in the flow chart, according to the combat effectiveness evaluation method based on a spatial information system of the embodiments of the present invention, including the steps of:

[0037] Step S1, constructing an initial combat effectiveness evaluation index system based on determining spatial information system capability requirements for combat tasks.

[0038] ​In this embodiment, the determination of the space information system capability is specifically carried out by analyzing the main mission, combat tasks and target requirements of the space information system, analyzing the composition structure, combat style and combat process of the weapon and equipment system space information system from the perspective of information support, analyzing and proposing the capability requirements of the space information system for combat tasks, and then constructing the combat effectiveness evaluation index system of the space information system based on the analysis of the capability of the space information system.

[0039] Based on the results of capability requirement analysis, an initial indicator system set is constructed. The construction of the indicator system set is the premise and basis for constructing the domain mapping matrix. Therefore, the initial indicator system of the space information system is first constructed for the combat missions carried out by the space information system.

[0040] Step S2: Through the indicator system construction method, the task domain and the indicator domain are analyzed and represented in a correlation manner, the mapping relationship between the task and the indicator is determined, and the combat effectiveness indicator system set corresponding to the initial combat effectiveness evaluation indicator system is constructed.

[0041] In this embodiment, a method for constructing an indicator system is proposed to reveal the mapping relationship between tasks and indicators. For example, the correlation analysis between the task domain and the indicator domain can be performed through models such as CMM, DMM (domain mapping matrix), DCMM, DCAM, and MD3M. By forming a mapping relationship between tasks and indicators and exploring the relationship between them, it is possible to extract indicators from different tasks for rapid evaluation. In this embodiment, the DMM model is preferably used to construct a combat effectiveness indicator system set. Specifically,

[0042] refer to Figure 3 , which is the overall framework diagram of the DMM-based indicator system construction method provided in this embodiment. The domain mapping matrix is ​​a method used to represent the information interaction relationship between two domains. The matrix is ​​composed of m row domain elements and n column domain elements, and is denoted as:

[0043] DMM i→j =(m ij ), i=1,2,…,m; j=1,2,…,n;

[0044] Among them, the matrix element m ij The value is 0 or 1. If m ij =1, it means that the column domain element j outputs information to the row domain element i, or the column domain element j exerts influence on the row domain element i; if m ij =0, it means that there is no information transmission relationship between the corresponding row and column domain elements, or there is no direct connection between the two.

[0045] On the basis of the index system of the spatial information system constructed by the capability requirement analysis of the task-oriented spatial information system, the embodiment is aimed at the problem of multiple types of combat tasks of the spatial information system. The traditional index system construction method is to establish an index system for a specific combat task by construction principles and expert consultation method. In order to be able to quickly evaluate different tasks in the evaluation process, the embodiment performs correlation analysis on the task domain and the index domain by the DMM model, forms a mapping relationship between the task and the index, and explores the relationship to extract the index for quick evaluation in different tasks.

[0046] Step S3, determining the index system of the spatial information system for a specific task according to the combat effectiveness index system set, and obtaining the index data by simulating the index system of the spatial information system through the simulation system.

[0047] The step of obtaining the index data by simulating the index system of the spatial information system through the simulation system specifically includes the following step: step S301, designing a simulation system for a specific combat task, establishing a combat scheme, and obtaining evaluation sample indexes by simulation; wherein the combat scheme includes determining the weapon equipment used in the combat process for a specific combat task, and determining the required reconnaissance satellite platform, communication satellite platform, navigation satellite constellation and / or attack weapon components in combination with specific related data and actual combat.

[0048] In the embodiment, in step S301, the weapon equipment used in the combat process is determined for a specific combat task. In order to ensure that specific simulation data is obtained, the reconnaissance satellite platform, communication satellite platform, navigation satellite constellation and attack weapon used in the support scheme are determined in combination with specific related data and actual combat. In a specific embodiment, the specific components can refer to Table 1 and Table 2:

[0049] Table 1, specific components of weapon equipment

[0050]

[0051] Table 2, satellite orbit parameters

[0052]

[0053] In the embodiment, in order to realize the combat performance analysis of the weapon equipment of the space information system, the above weapon list is taken into account, and considering that the evaluation object is a space-based information support equipment system, different satellite types are involved, and different types of satellites are combined in terms of quantity, wherein the navigation satellite selection strategy is no failure satellite, 3 satellite failures and 6 satellite failures, so as to evaluate the influence of the navigation satellite positioning capability on the completion of the combat task. For optical reconnaissance satellites, electronic reconnaissance satellites and SAR reconnaissance satellites, a fixed number of satellites are extracted to participate in the combat to form different combat schemes. Therefore, 1200 combat schemes are set as shown in Table 3:

[0054] Table 3, combat scheme composition method

[0055]

[0056] The task target area is the activity area of the blue ship, including the ocean and island environment, and the activity time is 120 hours. The underlying index data is obtained through the joint simulation of STK and MATLAB, and the specific simulation steps are as follows:

[0057] (1) Use MATLAB to connect MATLAB to build an initial scene, wherein the parameters of various satellites and their payloads refer to Tables 1 and 2.

[0058] (2) Use MATLAB to realize the simulation calculation of different schemes in Table 3 in STK, and save the index data of each scheme.

[0059] (3) Normalize the collected index data to obtain the final underlying index data as shown in Table 4.

[0060] Table 4, index value of combat scheme

[0061]

[0062]

[0063] Step S4, according to the evaluation sample index, determine and divide each subsystem contained in the space information system, determine the combat process causal relationship between the space information system and the subsystem, and construct a causal relationship diagram.

[0064] According to the above steps, the determination of each subsystem can determine the capability demand according to the composition elements determined in step S301, and determine the subsystem supporting each capability.

[0065] In this embodiment, the spatial information system can be subdivided into four parts according to its capabilities: reconnaissance and surveillance system, early warning detection system, satellite navigation and positioning system, and satellite communication system. The situational awareness system composed of the above four parts is responsible for acquiring, processing and distributing battlefield situation information, and divides the combat units into firepower strike system and command and control system, and describes the relationship between each subsystem in terms of information transmission direction.

[0066] by Figure 4 For example, Figure 4 By analyzing the combat process shown in the figure, it can be found that the four parts of the space information system are mainly involved in the firepower strike mission, namely reconnaissance and surveillance, satellite navigation and positioning, and satellite communications. According to the capabilities, they are divided into reconnaissance and surveillance capabilities, navigation and positioning capabilities, and communication support capabilities. The attack system corresponds to the firepower strike capability. Through simple analysis, it can be found that the firepower strike capability of the attack system will be affected by factors such as reconnaissance and surveillance capabilities, navigation and positioning capabilities, and communication support capabilities, and the survival probability of the blue side's ships will in turn have a negative impact on many subsystems of the red side. Based on this, the following can be drawn: Figure 5 A causal diagram of the relationships between system components, with negative and positive feedback represented by arrows.

[0067] Step S5: construct a basic flow rate tree for each subsystem based on the index system of the spatial information system obtained in step S3, and construct an SD model based on the constructed cause-effect relationship diagram.

[0068] In this step, the SD flow rate basic tree modeling method is adopted. First, the system is divided into several subsystems and the models are constructed separately. Then, they are combined and connected according to the cause-effect relationship, which makes the modeling process simpler and more accurate, and improves the objectivity and accuracy of the empirical formula in the SD model.

[0069] The basic definition of flow rate in-tree: If there is a point v(t) in a dynamic directed graph T(t) = (V(t), X(t)), such that any point u(t)∈V(t) in T(t) can find one and only one directed path from u(t) to v(t), then T(t) is called an in-tree. v(t) is called the root of the tree, u(t) that satisfies the in-degree d(u(t)) = 0 is called the tail of the tree, and the directed path from the tail of the tree to the root of the tree is called a branch. The number of nodes from the tail of the tree to the root of the tree is the branch length of this branch. If the rate variable is regarded as the root of the tree and the state variable is regarded as the tail of the tree, it can be called a flow rate in-tree. For details, please refer to the following. Figure 6 If the length of each branch of a flow rate tree is 1, it is called a basic flow rate tree.

[0070] In this embodiment, the SD model building steps are as follows:

[0071] (1) Based on the causal relationship diagram analysis of spatial information system variables, the stock-flow variables are determined, specifically,

[0072] {[L1(t),R1(t)],[L2(t),R2(t)]....[L n (t),R n (t)]};

[0073] Wherein, L(t) is the stock, R(t) is the flow, and n is the number of subsystems;

[0074] (2) According to the spatial information system capability, the subsystems are divided, and the flow rate basic input tree is established for each subsystem, wherein the tree root of each tree is R i (t), the tree tail is L1(t) to L n (t), A1(t) to A n (t) and the like are constants or auxiliary variables, which can be referred to as Figure 7 shown, a flow rate basic input tree diagram of the constructed subsystems provided in the embodiment;

[0075] (3) The sub-flow diagrams are combined and connected according to the causal relationship diagram to form the final stock-flow model.

[0076] Step S6, according to the combat process, the simulation is carried out through the constructed SD model, and the combat effectiveness is calculated according to the simulation result data to realize the combat effectiveness evaluation.

[0077] In this embodiment, the final combat effectiveness evaluation can obtain the final effectiveness value through the weighted summation method, but the result precision of this kind of solving method is low, for example, the system combat effectiveness evaluation and optimization method review published by Zhang Ziwie, Guo Qisheng, Dong Zhiming et al. in the system simulation journal in 2022, referring to this paper, WS is the most commonly used method in multi-attribute decision-making, as early as in 1923, Edgeworth began to study the weighting problem in test statistics, this method determines the weight of each index according to the actual situation, and then obtains the comprehensive effectiveness value through linear weighted average method. It is shown that the weighting method is widely recognized.

[0078] In order to solve the problem that the index and the combat effectiveness value are nonlinear and uncertain, and accurately describe the combat effectiveness of spatial information system, the description of combat effectiveness in this embodiment will be determined from two aspects of time factor and anti-interference factor, and the specific analysis is as follows.

[0079] In a specific embodiment, the space information system supports the fire strike, and the strike process includes the initial reconnaissance stage and the fire confrontation stage, and the space information system runs through the whole process. In order to accurately describe the operational effectiveness, the "kill chain of time-sensitive targets" is used for reference. It is a specific combat concept based on the concept of observation-judgment-decision-action (OODA), and the kill chain includes six stages of discovery, locking, tracking, positioning, engagement and evaluation.

[0080] According to the above six stages, the operational effectiveness of the space information system includes two aspects, one of which is reflected in the closing loop time of the kill chain of the fire strike under the information support, and the other is reflected in the anti-interference ability in the face of the blue side interference. Therefore, the description of the operational effectiveness will start from the time factor and the anti-interference factor, which are specifically,

[0081] The time factor represents the change of the time length of completing the strike task under different equipment parameters. Therefore, the time factor μ is defined as follows:

[0082]

[0083] Where T total is the duration of the operation, T is the time spent from the beginning of reconnaissance to the end of the strike, T will change with the change of the equipment parameters, T best is the time required to perform the operational task under the best operational assumption.

[0084] The anti-interference factor represents the anti-interference ability of the overall ability of the space information system under the blue side counter-interference after the implementation of the fire strike. The anti-interference factor η is defined as follows:

[0085]

[0086] Where F2 represents the information support ability value when the strike is completed, C23 is the standard line when the information support ability reaches the fire strike standard, F2 best represents the information support ability value when the operational task is completed under the best operational assumption.

[0087] In this embodiment, in order to accurately describe the operational effectiveness of the space information system in the process of performing the operational task, the weights of the time factor and the anti-interference factor are both set to 0.5, and β 作战效能 is calculated as follows:

[0088]

[0089] In this embodiment, taking the visible light reconnaissance satellite as an example, four satellites are selected from five visible light imaging satellites to perform information support tasks, so as to analyze the influence of each satellite on the information support task. The remaining weapon equipment is selected according to scheme 400. Therefore, schemes 25, 50, 75, 100, 125 and 400 are selected.

[0090] Table 5, scheme setting

[0091]

[0092] Table 6, combat effectiveness value

[0093]

[0094] In combination with the scheme setting, the values of satellites G1 and G5 to F2 have greater influence, and the influence on the anti-interference ability when entering the combat confrontation stage is also the greatest, so the performance improvement of satellites G1 and G5 can have greater benefits for the improvement of the final information support ability.

[0095] The method provided by the application uses a task-based capability requirement analysis method to construct a task-oriented space information system combat effectiveness index system set, and on this basis, uses a field mapping matrix to establish a mapping from a task field to an index field, forms a mapping relationship between a task and an index, and realizes the extraction of indexes in different tasks for rapid evaluation by exploring the relationship, and further realizes the combat effectiveness evaluation of the space information system by establishing a space information system simulation model based on system dynamics on the basis of the index system.
