基于数字电视广播(DTV)的外辐射源探测系统,因为其抗隐身、反侦察、生存能力强和可靠性高等特点,成为现有探测技术的一种有效补充,备受各国重视。对于外辐射源雷达系统而言,选用的机会照射源的信号特性是决定系统性能的关键因素之一。对DTV信号特性进行分析,为基于数字电视信号的外辐射源雷达的设计提供重要的基础。
External radiation source detection system based on Digital Television Broadcasting (DTV) has become an effective complement to the existing detection technology because of its anti-stealth, anti-reconnaissance, survivability and high reliability, which have attracted much attention of all countries. For the external radiation source radar system, the signal characteristics of the selected opportunity illumination source is one of the key factors that determine the system performance. The analysis of DTV signal characteristics provides an important foundation for the design of an external radiation source radar based on digital television signals.
