摘　　要：将博弈论方法引入到解决雷达组网系统抗压制干扰能力的评估问题中。以雷达组网系统的不同部署方式的集合作为局中人Ⅰ的策略集;干扰机的不同干扰位置的集合作为局中人Ⅱ的策略集,基于鉴别信息的概念,推导了雷达组网系统关于发现目标的平均信息量的度量模型,提出了将纯局势的各单雷达信干比的加权和作为支付矩阵的对应元素。对上述三个要素构成的矩阵博弈进行了仿真分析,结果表明:该方法是可行的。The strategy set of game players Ⅰ was composed according to the deployment of netted radar system.The strategy set of game players Ⅱ was formed according to the position of the jammer.Based on the definition of the identification of information,the measuring models of the average amount of information which was related to detect targets were established.The idea was proposed that the weighted sum of the radars′ signal to interference ratio was used as the relevant elements of the payoff matrix.The simulation results of the matrix game consisting of the three key elements show that the method proposed is feasible.
