摘要
针对多站测向定位中的虚假定位现象,提出一种借助于误差椭圆技术消除虚假定位的方法。该方法首先确定误差协方差矩阵,然后得出误差椭圆参数,并根据这些参数对各个定位目标数据进行相容性判别,最后根据判别结果来消除虚假定位。软件仿真验证了该方法的有效性。
Aimed at the false-location in the multi-station crossing-location, this paper puts forward an algorithm which uses error-ellipse erasing false-location. The algorithm calculates error-covariance-matrix firstly, then calculates the parameters of error-ellipse, also estimates whether these location-data are consistent with each other according to these parameters. Finally it exploits the results to get rid of the false-location. Computer simulations show that this method is effective.
