摘要
基于三站对辐射源联合时差定位的原理,分析了影响空中运动目标定位精度的因素,研究了相对位置关系、信号噪声及多普勒频移对定位误差的影响,解决了空中运动目标定位误差定量评估的部分理论问题,并利用计算机仿真验证了研究成果。
Based on the principle of tri-station TDOA location towards emitters, some kinds of factors that affect the air movement target location precision are analyzed. The influence of the relative location, signal noise and doppler frequency shift to the location precision is researched,partial theoretic questions about the evaluation of the location error of the air movement target are solved.
