摘　　要：结合Chan定位算法,对四站无源被动雷达三维时差定位技术中的定位算法、模糊无解、精度分析进行了研究。给出了Chan定位算法的推导,分析了定位模糊和无解的原因;研究了定位性能,分析了时差测量误差和站址误差等因素对定位精度的影响;通过仿真研究了多种布站形式下的GDOP分布。Based on Chan algorithm, the positioning algorithm, fuzzy unsolved and the accuracy of 3-D time difference location of four-station passive radarare studied. The Chan algorithm is deduced, the reason for the fuzzy location is analyzed, and the location performance is discussed. With the influence of location accuracy caused by time difference measurement error, station location error and so on are ana- lyzed. The geometrical dilution of precision（GDOP） distribution in differentstation arrangementsis studied by simulation
