分布式雷达信号检测

Distributed Radar Signal Detection

本文将讨论一种分布检测系统,在这种系统中包括一组相互独立的检测器和一个中心处理器。此系统有高可靠性、强的生存能力和较短的判决时间。在对付电子干扰影响方面系统也较单站要好。 每一单站的检测性能(发现概率和虚警概率)都假设为己知,本文得出了分布检测时最佳检测器形式、分布检测器性能。并得出随着单站数目增加而检测性能提高的数字结果。

This paper deals with a distributed signal detection system, which consists of a number of independent local detectors and a fusion center. The system has the advantage of higher reliability and survivability and shorter decision lime than centralized systems. Such systems are expected to be more reliable and immune to electronic attack than monostatic radars.The detection performances (detection probability and false alarm probability) are assumed given. In. this paper the detection performance of the distributed radar signal detectors is given. The optimum detection decision statistics are shown and the detection performance of the detectors increases monotonically with the number of partitions.
