| 摘 要： | 针对雷达检测概率评估雷达网抗干扰效能方法的局限性,通过对雷达天线和检测概率模型的分析,利用单雷达检测/漏检事件,推导了干扰环境下雷达网的条件CRLB,给出了干扰条件下目标跟踪误差所能达到的一个下界,从而提出了组网雷达基于条件CRLB的效能评估方法,同时从理论上证明了雷达组网的优越性。实验仿真结果表明,SOJ干扰下,利用CRLB可以很明显地证明雷达网融合跟踪比单部雷达性能要好,能比较准确地评估干扰环境下雷达网的性能,因此所述方法具有一定的实际工程意义。

| Abstract: | At present,the effectiveness evaluation of radar network in presence of jamming is based on the analysis of the probability of detection,which has some limitation.While in the presence of SOJ,a more accurate and general method is in dire need.In this paper,models of radar antenna and probability of detection are presented at first,and then by use of detection/miss sequences the conditional CRLB in the presence of jamming is derived.Finally a method of effectiveness evaluation for radar network based on cond... |
