摘要

三星时差定位系统中, 当对多个距离接近、功率相当的雷达辐射源进行侦收定位时, 会产生时差定位解模糊。提出利用前一时刻与后一时刻观测量独立进行定位, 并对前后双时刻定位信息进行联合的算法, 有效剔除时差定位模糊解, 实现对多个雷达辐射源的高精确度定位。理论分析与仿真结果表明:对多个雷达辐射源进行单次三星时差定位时, 除真值外, 会产生模糊解; 通过联合双时刻定位结果, 可实现模糊解的剔除, 有效解决多辐射源解模糊问题。

Abstract

In the Time Difference Of Arrival(TDOA) location system, it will produce a TDOA location ambiguity when receiving and positioning multiple radar radiation sources in a short distance. A double-time combined algorithm by using the independent position information of the moment before and after is proposed to eliminate the TDOA location ambiguity solution effectively, and then achieving high precision of multiple radar radiation sources. Analysis and simulation results show that the double-time combined algorithm in TDOA location system can solve the multiple radiation sources range ambiguity problem effectively.
