| 摘 要： | 针对卫星多次观测定位点的估计问题,提出一种不依赖于先验知识的定位点综合算法.该算法首先分析了星载干涉仪测向体制的定位精度,并基于此提出利用定位误差协方差矩阵对定位点进行加权综合的方法.仿真实验表明本文方法可以提高定位精度.

| Abstract: | To deal with the location estimation problem in many observations by the satellite-borne interferometer,this paper presents a new location integration algorithm,which is independent of any prior knowledge.First,it analyzes the location precision of the satellite-borne interferometer.On the basis of this,it presents an integration algorithm of emitter loci by using the location errors covariance matrix as weights.Simulation results show that the location precision can be improved by using the new method. |
