基于CDR数字音频广播的外辐射源雷达实验研究

Experimental Research of Passive Radar Based on China Digital Radio Broadcasting

数字音频广播CDR (China Digital Radio)是我国自主研发的数字音频广播标准。本文首先从CDR 信号结构入手,然后探讨了基于该信号的外辐射源雷达信号处理的对应方法,最后介绍了开展基于CDR 数字音频广播的外辐射源雷达实验研究情况,实测数据验证了信号处理方法的有效性和利用CDR 数字音频广播实现无源探测的技术可行性。

China Digital Radio (CDR) broadcasting is a fresh standard of digital audio broadcasting which was developed by our country recently. Firstly,the signal characteristics are introduced in this paper;sencondly, the processing methods of CDR-based passive radar are studied. Finally this paper introduce the experimental progress. The results of measured data processing prove the validity of the signal processing method and the technical feasibility of using CDR broadcasting signal for detection.
