对于由ESM 和雷达组成的多传感器系统, 分析和推导了用ESM 对2D 雷达成功引导的概率解析表示式, 为求解成功引导概率提供了依据; 研究了ESM 对2D 雷达成功引导概率随一些特征参数的变化规律,并得出了4 个特性; 在多种情况下进行了成功引导概率的数值计算, 验证了成功引导概率的一些变化规律, 并得出了一些有意义的结论, 从而对研究和设计同地配置的ESM 对雷达引导系统具有一定的参考价值。关键词: 雷达; ESM; 引导; 传感器管理; 数据融合Abstract: A n analyt ical exp ression of the successful guiding p robability of using an ESM senso r guiding a 2D radar is derived fo r a co2located radar2ESM system. W ith the analyt ical exp ression, the successful guiding p robability can be easily obtained. The guiding p robability influenced by an ESM and a 2D radar is studied and four p ropert ies of the successful guiding p robability are p roved. N umerical calculat ion of the successfulguiding p robability is conducted fo r several cases and the results verify the p ropert ies of the successful guiding p robability. D iscussions are also made. The conclusions p resented in th is paperw ill be useful in the design of co2located radar2ESM guiding system s.Key words: radar; ESM (Elect ronic Suppo rtM easure) ; guiding; senso r management; data fusion
