双目标纯方位定位数据处理分析

Analysis on the Bearing-only Data Processing of Double Targets Tracking

本文从双基阵纯方位定位的基本原理出发,给出了卡尔曼滤波算法的模型,针对实际目标特点和滤波中容易出现的发散问题,对方位数据进行时空迭代后将解算数据进行航迹融合。仿真实验表明,该处理方法能够克服滤波发散,实现双目标有效跟踪,可以快速、稳定地完成目标运动要素的估计,有较好的工程应用价值。

This paper gives the Kalman filter mode based on the principle of the bearing-only two arrays.Aimed at the target characteristics and problem of divergent extension in filter,space-time iteration is taken for locating data and track-to-track fusion is made.Simulation experiments prove that the method could overcome the filter divergence,realize bi-objective tracking and estimate the target movement factors fast and steadily.
