多雷达联网目标检测能力研究

Detection Performance in Multistatic Radars

本文是研究由分布在各处的单部雷达所得信息综合（多雷达联网）工作模式时的目标信号检测的性能。多雷达联网是一个系统。此系统有一组分布在各处的，相互独立的单部雷达和一个能综合多部雷达信息的中心处理器。本文将分布式检测器的概念和雷达联网的性能结合在一起，从而可以得出在不同雷达布站和不同目标起伏条件下信号检测性能。此性能可以对雷达布站方法和比较单、多站雷达性能研究都带来益处。由于目标所在位置相对于每一站的斜距都不相同，因此每一站的所得信噪比也不尽相同，本文将给出综合后的系统发现概率（Ｐｄｏ）和虚警概率（Ｐｆａｏ）的计算和仿真结果。

This paper deals with a distributed detection system of multistatic radars, which consists of a number of independent local radars and a fusion center.This system has the advandage of higher reliability,survivability and immunity to electronic attack than monostatic radars. In the paper, assume that the detection performance (such as detection probability and false alarm probability) in multistatic radars is given on condition:target movements, fluctuating targets and different positions of the radars.It is very useful to design the system of multistatic radars.
