空空导弹主被动雷达多模导引头研究

主被动雷达多模导引头是现代空空导弹末制导系统的一个重要研究方向。本文针对主被动雷达多模导引头设计时的关键技术,如宽频带天线罩、主被动复合天线、高灵敏度接收机、信息融合处理等技术,及其实现途径进行了分析,指出导引头设计时尤其要注意宽频带天线罩、复合天线设计时的数字补偿以及抗干扰性能设计时的主被动测量信息的融合处理。

Study on Active and Passive Radar Seeker of AAM

The research for an active-passive multimode radar seeker is an important trend to end guided system of air-to-air missile.This paper analyzes some critical techniques in the course of developing and the ways of their realization.These critical design techniques are broadband dome,active-passive composite antenna,higher sensitive receiver and information fusion processing.Finally,the paper points out that the digital compensation when developing broadband domes and composite antennas,and the active-passive measuring information fusion when the antijamming performance design should be paid more attention to.
