针对无源传感器交会定位有偏估计问题,提出了无源传感器交会定位精度分析方法。该方法利用目标位置坐标估计误差的偏差均值,衡量了目标位置估计产生的相对固定偏差量;利用目标位置估计值的标准差,衡量了目标位置估计的精度。仿真验证表明,该方法计算简单且验算结果准确,适用于不同数量、位置和精度的被动传感器布阵,具有良好的理论研究和工程应用前景。

Aimed at the bias estimate problem of the cross location of passive sensors,a cross location accuracy analysis method for passive sensors is proposed.The method can measure the relative errors of object location estimate by the mean deviation of object location estimation error and the precision of object location estimate by the relatively fixed deviation of object location evaluation.The simulation results show that the method is simple and accurate,thus it is suitable for the passive sensor disposal of different numbers,positions and precisions.The method has prospects of theoretical research and engineering application.
