摘要

近年来，低空监视的需求急剧增加，无源雷达受到越来越多的关注。在本次实验研究中，我们在武汉大学开发了一个基于多调频的无源雷达系统。结果表明，采用数字波束形成(DBF)方法可以同时提取不同方向的直接波作为参考信号。利用该技术，在不增加硬件系统复杂性的前提下，实现了多调频信道联合探测，提高了调频无源雷达的探测稳定性。

Experimental Research of Multi-FM Based Passive Radar

In recent years, the demand for low-altitude surveillance has increased dramatically, and passive radar has received more and more attentions. In this experimental research, we develop a multi-FM based passive radar system in Wuhan University. It is demonstrated that the digital beamforming (DBF) method can be used to simultaneously extract direct waves from different orientations as reference signals. Using this technique, we achieve multi-FM channel joint detection without increasing the complexity of the hardware system, which improves the detection stability of FM based passive radar.
