摘要: 多传感器时差定位系统中,接收预处理与时间频率基准源会导致系统时差,同时观测站几何位置测量的不准 确性也会引入站址误差。针对系统时差与站址误差对定位误差的影响,研究了在已知地理位置引入参考站,通过差分 目标信号时差值与参考信号时差值,抑制系统时差与站址误差对定位的影响,实现对系统时差与站址误差的校正。仿 真结果表明,在定位盲区之外引入参考站可以提高参考站附近区域的定位性能。

Abstract: According to the impact of the location error by the observer's position error and inherent time difference caused by the receiving and preprocessing module and time and frequency reference source and in multi-sensor time difference of arrival(丁DOA) location system, the error calibration algorithm based on reference station in known loca- lion is analyzed. The impact of location is eliminated by substracting the signal TDOA between target and reference, and the observer's position error and inherent time difference arc corrected. Simulation results show that location perfor- mance at the regional near the reference is improved when the reference stations are outside the location blind area.
Key words: TDOA location, Location error, Reference stations
