摘要
介绍了双同步卫星无源定位系统基于接收干扰源辐射信号的到达时间差(TDOA)和到达多普勒频率差(FDOA)对干扰源实现定位的原理,重点研究了卫星相对地面接收站和干扰源的不同位置和不同速度对定位误差的影响,通过改变双同步卫星的位置与速度,仿真分析不同卫星构型时定位误差曲线,得到定位精度较高时的卫星位置构型和速度构型。
The principle of dual-GEO satellites passive location system for satellite interference based on time difference of arrival(TDOA)and frequency difference of arrival(FDOA)of the interference source is introduced in this paper.This paper focuses on studying the influence of different positions and speeds of the satellites relative to the ground receiving station and the interference source on the positioning error.By changing the positions and speeds of the dual-GEO satellites,the curves of positioning error under different satellite configurations are analyzed by simulation,and the position and speed configurations of the satellites with higher positioning accuracy are obtained.
