摘　　要：研究了利用外辐射源信号作为发射信号,接收站位于导弹平台的外辐射源雷达制导系统。该体制雷达制导系统自身不发射电磁波,具有很强的抗干扰性能。通过对该体制雷达制导系统的作战性能、系统特性、技术特点等方面进行分析,并以DVB-T信号作为外辐射源制导系统的发射信号,对系统的作用距离、分辨性能等进行了仿真,得到的距离和速度测量精度能够满足弹上雷达导引头对目标引导信息的精度要求,可作为引导信息提供给雷达导引头,实现地面制导雷达的功能。因此,采用外辐射源体制可以有效提升制导系统的干扰对抗性能和设计灵活性,降低系统的设计复杂度和研制成本,为制导系统的设计提供一种新的思路。A passive radar guidance system with the receiver on the missile is discussed,which does not emit electromagnetic waves and has high anti-jamming performance.The system performance is analyzed,including the guidance performance,the system characteristics,the technical characteristics,and so on.The detection ability and the resolution characteristics are simulated using the DVB-T signal as the transmitter.It can provide the guiding information of the distance and velocity for the radar seeker in replacing of the ground-based guidance radar.And the measurement accuracy is high enough to guiding and tracing the air target.Therefore,it provides a new idea for the design of guidance system,which can effectively enhance the anti-jamming performance and design flexibility,reduce the design complexity and system costs.
