动基站时差探测系统定位方法研究

Research on Location Method of Moving Platform Detection System

针对传统长基线时差探测系统的缺点,提出了全新的动基站时差测量系统并给出了目标的定位原理。在典型布站、信息存在冗余的前提下,通过子集选优法确定了最佳定位算法,并根据工程应用的需要确定了更加合理简捷的定位算法,统计仿真表明了该算法的有效性。最后,计算了目标高度测量精度并归纳了其特点,给出了有益的结论。

A new detection system applying moving platform, which overcomes the shortcoming of traditional long baseline time difference of arrival （TDOA） detection system, is presented, and its principle are also included. Optimal location method is deduced on typical disposition and redundant condition, furthermore ,one more practical method is inferred, its availability in engineering is proved by Monte Carlo simulation. Height location accuracy is calculated, and useful conclusions are given in the end.
