摘要: 在测向交叉定位的基础上,提出了一种根据测向误差概率分布特性估计目标位置的方法.在利用最小二乘法获得定位初值后,根据每次角度测量的信息进行目标位置估计.与常规方法相比,这种方法不需要进行大规模的矩阵运算就可较精确地估计出目标的位置.最后进行了计算机仿真验证.

Abstract: This paper develops a method to estimate position of emitter based on distribution characteristics of bearing measurement errors.Having obtained an initial position with a least-square method, a more precise result can be worked out from information contained in the bearing measurements.Better results are attainable by using this method without la rge-scale matrix operations.Simulation results show its effectiveness.

Key words: probability estimation, bearing-only measurement, single observer passive location
