针对运动单站采用两个观测点进行无源定位时定位精度差的问题,介绍一种基于运动单站的多观测点交叉无源定位技术.采用Matlab对多个数量观测点的处理进行仿真与分析,并与两个观测点的效果进行对比.仿真及对比结果表明,选取的有效观测点数越多,其定位收敛速度、效果越好.由于其在工程实现上的可行性以及适用的广泛性,该技术具有一定参考价值.

Aiming at the poor positioning precision of two observation points in the single moving station in the process of passive location,a passive location technology for crossing angle of multi observation points based on single moving station is in-troduced in this paper. With Marlab,the processing of multiple observation points is simulated and analyzed,and the effects of two observation points are compared. The results show that the more the effective observation points are adopted,the better ef-fect and faster convergence speed can reach. Moreover the technology has the advantages of feasibility and wide applicability,so it has a high reference value.
