摘要
机载无源测向系统是信息战的重要信息源。本文阐述了干涉仪测向、比幅测向与和差波束测向等常用机载测向技术基本原理,并进行了测向误差影响分析。最后根据几种测向技术的工作特点,分析了典型应用场景,为无源探测系统测向方案选择提供参考。
Passive direction-finding(DF) system is significant to information war.This paper first expounds the basic principle of interferometer DF,amplitude comparison DF and sum-and-difference-beam DF,and then DF precision is analyzed.Finaly,an analysis of application scenarios if done according to their features,which is significant and valuable to system design.
