无源雷达时差定位方法研究

用民用蜂窝基站发出的信号作为信源,对目标所反射的蜂窝信号进行接收处理,利用到达时间差定位方法,可以实现对目标的定位.基于蜂窝通信系统的无源雷达尤其适合探测超低空飞行目标,克服了传统雷达存在超低空探测"盲区"的缺陷,具有优良的远程预警能力.

Time Difference of Arrival Location of Passive Radar

Using the signals sent by civil cell network base station as the source,receiving and processing signals reflected by the target using TDOA method can realize the location of that target.Passive radar based on cell network communication system is especially suitable for the detection of minimum altitude flying targets,and it has overcame the disadvantage of blind areas in minimum altitude detection,it has been testified that it have fine remote early warning ability.
