摘要
讨论了多站时差定位技术用于再入低高度目标轨迹测量的问题,首先介绍了多站时差定位方法的基本原理,然后结合现有的遥测系统分析了采用多站时差定位技术时产生误差的原因,并给出了可能达到的定位精度,最后探讨了目前改善定位精度的几种可行办法。
The locating technology based on arrival time differences of reentry low altitude target is discussed.Its basic principle is introduced firstly,and then the error sources in the existing telemetry system and corresponding precision are discussed.Some methods that can improve location precision are proposed lastly.
