基于外照射源的双基地雷达探测系统研究

利用外照射源对目标进行探测是目前电子对抗研究的一个热点,因为该体制雷达具有良好的“四抗”性能。文中首先介绍了该体制雷达进行目标探测的数学模型和关键技术;其次针对目前使用的外照射源,分析了它们各自的特点;最后给出了以调频广播信号为外照射源进行目标探测的一个实验系统,利用该实验系统采集的回波数据进行仿真,结果表明该体制雷达不仅具有很好的目标检测性能,而且在一定程度上满足了当今电子战发展的要求。

A study on the bistatic radar detection system based on non-cooperative illumination

Target detection of the passive bistatic radar by non-cooperative illumination is a focus on which the current ECM study is made of for its advantages of "four countermeasures" . In this paper, mathematical models and key techniques of target detection for the passive bistatic radar are introduced firstly. Then the characteristics of some ideas concerning the use of "non-cooperative illumination"are analyzed. Finally, an experimental system taking FM signals as the non-cooperative illumination to carry out target detection is discussed. Simulation implemented via the echo data collected by the experimental system shows the passive bistatic radar not only has better performance of target detection, but also meets,to a certain extent,the requirements of the development of current electronic warfare.
