基于信息级的T-Rn型多基地系统定位方法研究
A Study on the Method of T-Rn Type Multi-station System Cooperating Target Localization Based on Information-level
摘要
Abstract
An information-level T-Rn type cooperating target localization method of the multi-station system is proposed in this pa-per, in which the concrete process is expounded of this kind of localization way .Firstly, single receivers complete the localization according to time-difference-direction-measurement information .Then, the center station applies the weighted least squares ( WLS) to merge together the localization results of the four receivers .After deducing the ranging and localization error formulas , several factors affecting the localization precision are analyzed while geometrical dilution of precision (GDOP) is applied to analyze the lo-calization error and the theoretical lower bound of error performance is deduced .It is demonstrated in the simulating experiment that the localization precision of the center station is much higher than that of a single receiver , reaching the Cramer-Rao lower bound(CRLB) of the error, having a kind of engineering applying value .关键词
