Description

Technical Field

[0001] The present invention relates to the technical field of satellite orbit game deduction, and in particular to a satellite orbit game deduction and evaluation method. Background Art

[0002] With the rapid development of computer technology and the continuous improvement of information technology, the use of computer systems to conduct simulation confrontation has become the main form of war simulation. Through computer simulation methods, distributed, parallel, and variable rate methods, it is basically possible to simulate all elements and processes of war. Satellite equipment is technology-intensive, small in number, high in cost, limited in service life, and highly politically sensitive. It is difficult to conduct high-frequency training based on real soldiers and equipment. Using digital parallel battlefields based on computer systems to conduct simulations can verify combat theories, evaluate combat plans, reduce training risks, and improve training effectiveness, providing an environment and means for research, verification, and training for space orbit games.

[0003] Space orbital game refers to the orbital evolution process and its results formed by two or more moving objects constrained by orbital dynamics in the gravitational field of a celestial body, actively exerting control actions under the support of their respective control capabilities and available information, and pursuing opposite, contradictory or inconsistent relative posture states. In a broad sense, orbital game includes both orbital motion problems involving orbital dynamics and posture motion problems affected by orbital motion coupling; in a narrow sense, orbital game only targets orbital motion problems, especially relative orbital motion problems.

[0004] The elements involved in space orbital games include orbital objects, state information, strategy sets, motion strategies, and orbital benefits. For different types of space orbital games, the information required for the task is obtained from the state information, and the motion strategy of the orbital object is designed. It is necessary to comprehensively consider the various constraints of the strategy set and design a motion strategy that meets the task requirements to maximize the orbital benefits.

[0005] Judging and evaluating the simulation results is an important part of space orbit game simulation and an important basis for verifying the simulation effect. In the vast space, spacecraft run at high speeds and are subject to many restrictions such as orbital attitude and fuel. Space orbit game has problems such as difficulty in evaluating combat effectiveness. Summary of the invention

[0006] In order to solve the technical problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a universal satellite orbit game deduction and evaluation method, which can be applicable to different orbits and different types of satellite orbit games, quickly give quantitative evaluation results, and provide an important reference basis for the generation and evaluation of satellite orbit game strategies.

[0007] To achieve the above-mentioned purpose, the present invention provides a satellite orbit game deduction and evaluation method, comprising the following steps:

[0008] Step S1, obtaining satellite orbit game deduction result data;

[0009] Step S2, obtaining satellite orbit game deduction mission target data;

[0010] Step S3: Calculate an evaluation score for the satellite orbit game deduction result according to the satellite orbit game deduction result data and the satellite orbit game deduction task target data.

[0011] According to a technical solution of the present invention, when both opposing parties have a single satellite, the satellite game deduction result data includes the task completion status, the actual orbit change amount consumed, and the actual consumed time; the satellite orbit game deduction task target data includes the maximum satellite orbit change amount and the maximum task time;

[0016] The calculation formula of the judging score is:

[0017] Score=∑ i λ i W i -∑ j μ j C j -∑ k α k F k -∑ l β l T l (2)

[0018] Among them, W i represents the task goal achievement attribute value of the i-th task. When the task goal is achieved, the value is 1, and when the task goal is not achieved, the value is 0i∈{1,2,…,n}, where n is the total number of tasks; C j represents the satellite loss attribute value of the j-th own satellite, which is the satellite loss rate, expressed as a percentage.

[0021] According to a technical solution of the present invention, it also includes:

[0022] Step S4, the satellite orbit game deduction includes multiple rounds of confrontation, counting the referee score of the satellite orbit game deduction result in each round, and calculating the total of the referee scores of multiple rounds.

[0031] like Figure 1 As shown, the present invention provides a satellite orbit game deduction and evaluation method, comprising the following steps:

[0032] Step S1, obtaining satellite orbit game deduction result data;

[0033] Step S2, obtaining satellite orbit game deduction mission target data;

[0034] Step S3: Calculate the evaluation score for the satellite orbit game simulation result according to the satellite orbit game simulation result data and the satellite orbit game simulation mission target data.

[0036] The calculation formula for the judging score is:

[0037] Score=λW-(αF+βT) (1)

[0041] The formula for calculating the judging score is:

[0042] Score=∑ i λ i W i -∑ j μ j C j -∑ k α k F k -∑ l β l T l (2)

[0043] Among them, W i represents the task goal achievement attribute value of the i-th task. When the task goal is achieved, the value is 1, and when the task goal is not achieved, the value is 0, i∈{1,2,…,n}, n is the total number of tasks; C j represents the satellite loss attribute value of the j-th own satellite, which is the satellite loss rate, expressed as a percentage (0-100%). When the own satellite is not lost, the value is 0, and when the own satellite is completely damaged, the value is 100%, j∈{1,2,…,m}, m is the total number of own satellites; F k represents the satellite orbit change amount attribute value of the k-th own satellite, which is the ratio of its actual consumed orbit change amount to the satellite's maximum orbit change amount, k∈{1,2,…,m}, where m is the total number of own satellites; T l Represents the task time attribute value of the lth task, which is the ratio of the actual consumed time to the maximum task time of the task, l∈{1,2,…,n}, where n is the total number of tasks;

[0044] λ i , μ j , α k , β l are all positive integer constants, among which λ i represents the task objective weight of the i-th task, μ j represents the satellite value weight of the j-th own satellite, α k represents the orbit change consumption weight of the kth satellite, β l Represents the time consumption weight of the lth task.

[0045] Furthermore, for normalized representation, the value range of the weights should be further constrained, for example, agreed to be:

[0046] According to a technical solution of the present invention, multiple tasks can be divided into different levels according to their importance, and tasks of different levels correspond to different task objective weights; multiple satellites can be divided into different types according to their criticality, and different types of satellites correspond to different satellite value weights.

[0049] Taking two rounds as an example, the scores of A and B are:

[0051] in, Indicates the score of side A in the first round; Indicates the score of side A in the second round; Indicates the score of Party B in the first round; Indicates the score of Party B in the second round.

[0052] The satellite orbit game deduction and evaluation method provided by the present invention is described in detail below in conjunction with specific embodiments.

[0053] The weights are configured as λ=10, α=3, β=1. According to the value type of the satellite, the satellite value weight and satellite loss weight are configured as follows: θ=1.0, η=1.0, μ=9 for high-value satellites; θ=0.6, η=0.6, μ=6 for medium-value satellites; θ=0.4, η=0.4, μ=3 for low-value satellites.

[0054] According to the formula, the quantitative results can be calculated as shown in the following tables.
