摘要
本文给出了一种平面时差定位方法,推导出无源定位的方程,并通过仿真分析系统存在的定位模糊问题,分析了基线之间夹角和基线长度对于定位模糊区域的影响,探讨了模糊性的消除问题,最后分析了定位精度。
A method of planar time-difference-of-arrival location is presented; and equation of passive location is deduced; and issue of location ambiguity existed in the system is analyzed by simulation. The affect of angle between two base lines and the length of base lines on ambiguous area of location is analyzed and the solution to eliminate the ambiguity is discussed. Finally,the accuracy of location is analyzed.
