Evaluation Of Radar Anti-Jamming Ability Based On Game Theory

Radar,as a member of the electronic warfare,the clairvoyance of the battlefield,has been widely used,and all kinds of new system and new technology are increasingly emerging,but because of its characteristics of the original rational,radar is easily limited and targeted,the evaluation of radar anti-jamming capability is of great significance.At the same time,radar and jammer game with each other,the process both has complex technical factors and a lot of uncertain factors, so it is necessary to use the relevant theories of game theory to analyze these factors.The core problem of this paper is the application of game theory in radar anti-jamming capability assessment.paper’s main work is as follows:1.Introduce the research background and significance of this article,introduce the dynamic research of game theory applied in radar anti-jamming performance evaluation.2. Analyze the radar anti-jamming evaluation problem from different angles deeply,discuss on the feasibility of application of game theory to the radar anti-jamming evaluation preliminarily.3.Combining with the characteristics of radar countermeasures problem,the related theories of game theory are analyzed,including the three basic elements of game,two finite zero-sum game,the timing of signal game and the solving method, and the game model which discusses the competition relationship.4.In fact,radar confrontation is not only an incomplete information dynamic game process,but also meet the requirements of signal game.This paper originally bring the nalysis model of signal game in the research of radar countermeasure,to study the problem which exist in a variety of complex technical and human factors.Then,the basic hypothesis has been carried on,the subgame perfect equilibrium strategies of jammer and radar have been deduced,the pooling equilibrium and separating equilibrium of different situations have been obtained.Finally,to use burn-through range as the game payoff function,simulate the behavior of the mutual game in real combat,validate the correctness of the model,and puts forward the research problems.5.Based on game theory and radar anti-jamming capability evaluation model of the grey correlation analysis.analyzes the factors affecting radar anti-jamming ability, on the basis of the radar anti-jamming capability evaluation index system is established.in order to overcome the single method to determine the weight of one-sided,combination determining index weight,combined with the characteristics of radar anti-jamming capability assessment is established to improve the decision model of grey association analysis,finally using the instance radar anti-jamming capability has carried on the comprehensive evaluation.
