摘　　要：采用四站时差定位算法,能够唯一确定辐射源目标的位置信息。除了时间测量误差、站址误差外,布站方式也是直接影响时差定位精度的重要因素。通过理论分析和模拟仿真的方法,研究布站方式对四站时差定位精度的影响,对工程应用有较好的指导意义。The target location information is confirmed by four-station time difference of arrival(TDOA)location algorithm.Besides time measurement error and position error,station layout mode has a direct impact on positioning accuracy of TDOA location.This paper studies the impact of station layout mode on positioning accuracy of four-station TDOA location through theory analysis and simulation,which is of guidance significance for engineering application.

关 键 词：布站方式 定位精度 四站时差定位
