【摘要】：雷達(dá)（Radar）作為電子戰(zhàn)中的一員，好比戰(zhàn)場中的千里眼，得到廣泛應(yīng)用，不斷涌現(xiàn)各種新體制和新技術(shù)，但因其原理性的特點易被限制和針對，因此對于雷達(dá)抗干擾能力的評估具有十分重要的意義。同時，雷達(dá)抗干擾和干擾機干擾之間互相博弈，其中既有復(fù)雜的技術(shù)因素，也含有大量的人為因素，因此有必要利用博弈論的相關(guān)理論對這些因素進行分析。 本文研究的核心問題是博弈論在雷達(dá)抗干擾能力評估中的應(yīng)用研究。論文的主要工作如下： 1.介紹了本文的研究背景、意義，以及博弈論在雷達(dá)抗干擾性能評估中應(yīng)用研究動態(tài)。 2.從不同角度深入分析雷達(dá)抗干擾評估問題，初步探討了博弈論應(yīng)用到雷達(dá)抗干擾評估中的可行性。 3.結(jié)合雷達(dá)對抗問題的特點介紹了博弈論的相關(guān)理論，包括構(gòu)成博弈的基本要素、二人有限零和博弈、信號博弈的時序及求解方法以及旨在討論競爭關(guān)系的博弈集結(jié)模型。 4.雷達(dá)對抗實際上不僅僅是一個非完全信息動態(tài)博弈的過程，而且滿足信號博弈的要求，本文獨創(chuàng)性地將信號博弈分析模型引入到雷達(dá)對抗問題的研究中，用來研究這一問題中存在的各種復(fù)雜的技術(shù)因素和人為因素。在此基礎(chǔ)上進行了基本假設(shè)，分別討論了干擾機、雷達(dá)依存的子博弈精煉貝葉斯均衡戰(zhàn)略，得到了干擾機、雷達(dá)在不同情況下的混同均衡和分離均衡，最后以雷達(dá)燒穿距離作為支付函數(shù)，，模擬真實對抗中雙方互相博弈的行為戰(zhàn)略，驗證了這一模型的正確性，并且指出了在實際工程應(yīng)用研究中需要注意的問題。 5.將基于博弈論和灰色關(guān)聯(lián)分析的評估方法引入到雷達(dá)抗干擾能力的綜合評估上，分析了影響雷達(dá)抗干擾能力的因素，在此基礎(chǔ)上建立了雷達(dá)抗干擾能力評估指標(biāo)體系。單一方法確定指標(biāo)權(quán)重存在片面性，將權(quán)重組合起來考慮可一定程度上克服這一缺陷，引入博弈集結(jié)模型的思想相對傳統(tǒng)的線性組合方法，顯然更加科學(xué)合理。權(quán)重確定之后，結(jié)合雷達(dá)抗干擾能力評估的特性建立了改進的灰色關(guān)聯(lián)分析決策模型，最后利用實例對不同雷達(dá)的抗干擾能力進行了綜合評估。
[Abstract]:As a member of electronic warfare, radar radar has been widely used in battlefield, and many new systems and technologies have been emerging, but it is easy to be restricted and targeted because of its characteristics of principle. Therefore, the evaluation of radar anti-jamming capability is of great significance. At the same time, there are complex technical factors and a large number of human factors in the game between radar anti-jamming and jammer jamming. Therefore, it is necessary to use the relevant theory of game theory to analyze these factors. The core problem of this paper is the application of game theory in radar anti-jamming capability evaluation. The main work of this paper is as follows: 1. The research background, significance and application of game theory in radar anti-jamming performance evaluation are introduced. 2. The problem of radar anti-jamming evaluation is analyzed from different angles, and the feasibility of applying game theory to radar anti-jamming evaluation is discussed. 3. Combined with the characteristics of radar countermeasures, the paper introduces the relevant theories of game theory, including the basic elements of game, the two-person finite zero sum game. The time series and solution method of signal game and the game aggregation model to discuss the relation of competition. 4. Radar countermeasure is not only a process of incomplete information dynamic game, but also meets the requirement of signal game. In this paper, the signal game analysis model is introduced into the research of radar countermeasure problem. It is used to study various complicated technical factors and human factors in this problem. Based on the basic assumptions, the sub-game refined Bayesian equalization strategy of jammer and radar is discussed respectively. The mixed equalization and separation equalization of the jammer and radar in different situations are obtained. Finally, the radar firing distance is taken as the payment function to simulate the behavior strategy of the game between the two sides in the real confrontation. The correctness of the model is verified and the problems needing attention in practical engineering application research are pointed out. 5. The evaluation method based on game theory and grey correlation analysis is introduced to the comprehensive evaluation of radar anti-jamming ability, and the factors influencing radar anti-jamming capability are analyzed. On this basis, the evaluation index system of radar anti-jamming capability is established. There is one-sidedness in determining the index weight by a single method, which can be overcome to a certain extent by combining the weight. The idea of game aggregation model is more scientific and reasonable than the traditional linear combination method. After the weight is determined, an improved grey correlation analysis decision model is established based on the characteristics of radar anti-jamming capability evaluation. Finally, the anti-jamming ability of different radars is evaluated by an example.
