动基站时差定位技术研究

Research on Filter Algorithm of Moving Platform Detection System

针对传统无源长基线时差探测系统的缺点,提出了一种全新的动基站时差测量系统,介绍了探测系统组成、定位公式及其求解。在信息存在冗余的前提条件下,研究了目标的最小二乘法定位方法,提出高度简化的加权最小二乘算法,与最小二乘法相比较,显著改善了目标的测量精度,且计算量相对较小,仿真结果证明了该算法的有效性。

A new location system on moving platform, which improves the accuracy of measuring target position, is presented. Its composition and location principle are also described in this paper. A new simplified least square method is applied in information redundant condition, and not only the location accuracy is improved significantly, but also computation amount is greatly reduced. Its effectiveness is proven by simulation results.
