双站无源定位精度与布站仿真分析

摘要

根据定位平台与目标的几何关系、测向测时误差、定位精度要求等因素，对基于圆概率误差、定位模糊区和相对误差等不同指标的双站无源定位精度进行仿真，并分析不同态势下定位平台的布站形式，对双多站无源定位具有现实意义。%According to the factors such as the geometrical relationship between location platform and target ,direction finding (DF )/time finding error ,location precision request ,etc .,this paper simulates the precision of dual-station passive location based on the indexes such as circular proba-ble error ,ambiguous location area and relative error ,etc .,and analyzes the station distribution type of location platforms under different situation ,w hich is valuable to analyze the double/multiple sta-tions passive location .
