数字地面多媒体广播外辐射源雷达目标探测实验研究

摘要

数字地面多媒体广播(DTMB)是我国具有自主知识产权的数字地面电视广播标准，该文介绍了利用武汉大学研制的多通道外辐射源雷达实验平台开展DTMB外辐射源雷达研究的情况。论述了该体制雷达的工作原理、关键技术、探测设备和外场实验，给出了目标探测初步实验结果，从实验上证实了利用DTMB信号实现目标探测的技术可行性。%Digital Terrestrial Multimedia Broadcasting (DTMB) is announced as the Chinese own independent intellectual proprietary digital terrestrial TV standard. A passive radar system is introduced for target detection based on DTMB. The principle, key techniques, experimental equipment and preliminary results are given. The technical feasibility of using DTMB signal for target detection is proved by field experiment.
