本文阐述了分布式雷达目标检测理论,该雷达系统使用了多个分布在四周的接收机和检测器及一部中央处理机,它依靠四周的判决组合作出最终判决,而不是依靠统计判决。就整个系统最优化,研究了各种不同的组合策略。已证明,一个外部检测器的最优判决策略与其它各外部检测器的策略有关,而且,有趣的是,它也与中央处理机的结构有关。为了说明这种理论的应用,本文研究了瑞利衰落环境中分布式系统的设计。
This paper describes the theory of distributed radar target detection, which uses multiple receivers and detectors distributed all around and a central processing unit. It relies on four-week combinations of decisions to make the final decision, rather than relying on statistical decisions. On the whole system optimization, studied a variety of different combination strategies. It has been shown that the optimal decision strategy of an external detector is related to the other external detector strategies and, interestingly, it also relates to the architecture of the central processing unit. In order to illustrate the application of this theory, this paper studies the design of distributed systems in Rayleigh fading environment.
