摘要
基于外辐射源的运动目标探测、定位与成像技术是目前新体制雷达研究的热点之一。文中介绍了基于外辐射源的无源雷达对运动目标成像的研究现状,分析了利用电视或调频广播等外辐射源信号作为机会照射源的多基地无源雷达成像系统的构成和基本原理,并且选取了12个电台信号作为外辐射源,利用无源雷达成像技术对运动目标进行了仿真实验,最后探讨了该无源雷达成像体制的若干关键技术和应用前景。
The techniques of detection, location and imaging of moving target based on external illuminators are now a very interested research field in new style radar system. The present situation of research and development of such passive radar imaging system is introduced in this paper. The configuration and basic principle of multistatic passive radar imaging of moving target are analyzed by using multiple TV and broadcast signals. The imaging simulations are performed using 12 TV station signals. In addition, several key technologies and application perspective of this kind of radar system are discussed.
