摘要
研究了一种基于空间非合作运动辐射源照射的无源探测系统。根据时差定位的基本原理,在不能采用直接测量获得时差信息的条件下,提出了一种间接的获取时差信息的方法,经过理论推导和仿真分析,结果表明该方法的目标定位精度能够满足对目标的定位与跟踪需求。
In this paper,a passive detection system based on special non-cooperative motorial emitter illuminating is studied.According to the basic principle of time difference locating technology,a indirect measurement way of TDOA is provided because the direct measurement can not get the TDOA.The theory derivation and simulation analysis show that this indirect way can meet the requirement of target-tracking.
