便携式无源探测雷达研究

Research on Portable Passive Detecting Radar

针对静默哨兵系统等隐身雷达的战场机动能力不足,提出了一种便携式无源侦察系统的设计方法。通过三点布站对目标测距定位,对信号作相关处理提高侦测距离,用时域遍历代替相控天线在空域遍历实现多目标功能。方法简洁、造价低廉,对构建国土和城市重点防御有一定参考价值。

Passive radar such as Silent Sentry system has disadvantages of low mobility in battlefield;therefore design of a portable passive detecting system is presented.To measure range of target by way of tri-point location;to improve range coverage through signal correlation processing,and to realize multi-target capability by replacing space-domain scanning of phased array antenna by time domain scanning.This method is easy to implement with low cost,which provides useful reference for national and city defense.
