A correlator and a detection method are presented. The detection method is modified from "Appollo" ranging system and suitable specifically for tone-code mixed ranging system. In the "Appollo" system the maximum likelihood detection was used, while in the present detection method setting of detection threshold is float.In comparison with"Appollo"system it has obvio us advantages: cor-relation loss decreases by 6dB and configuration is very simple. These feat-ures have been proved in use.

In this paper a novel scheme for anti-ship missile radar seeker is proposed. The theoretical basis of the scheme is the obvious difference in the depolarization between the warship and the chaff cloud. In order to examine the properties of the scheme, the depolarization characteristics of the chaff cloud are firstly analysed. Particularly, the depolarization factor is defined and its probability density is deduced. Thereby, a maximum likelihood detection system to identify chaff interference from naval vessels provided and its error detection probability is calculated. Finally, several measuresto reduce the error detection probability are discussed. The results show that the sequential detection method is a better one to settle the contradiction between enhancing identifying performance and shortening observation time.

反航导弹雷达导引头识别箔条云新方案──极化识别方案是建立在箔条云和舰艇去极化特性具有显著差异基础上的。为了分析该方案所能达到的性能,本文首先采用严格的理论方法分析箔条云的去极化特性,并定义去极化系数和推导去极化系数的概率密度函数。在此基础上,构造了一个用于识别箔条云与舰艇的最大似然检测系统,并对该系统的错误概率进行了计算。最后讨论降低错误概率的几种途径,重点讨论了序列检测方法。研究结果表明,该方法较好地解决了提高识别性能与缩短观测时间的矛盾。
