机载无源定位系统的多点定位及精度分析

Multipoint Location and Its Accuracy Analysis Based on the Airborne Passive Location System

利用方位测量定位的原理,介绍了机载无源定位系统多点定位的方法,建立了定位的数学模型,分析了具体情况下的多点定位国概率误差与距离、测向点个数以及初始角的关系,并通过仿真结果提出了提高定位精度的改进措施。

In this paper, by using the theory of azimuth measurement location, a method of multipoint location is introduced, and a mathematic model of location set up. The relationship of circular error probability and range, the number of measure-points, as well as initial angle is analysed respectively under a certain condition.The measurements to improve location accuracy are presented by the simulation results.
