Short summary
Indoor positioning technology is used in all aspects of life. We study the positioning method of a UWB radar network. Because of the interference in the indoor environment, the UWB radar measurement data produce abnormal values. In order to eliminate the outliers, the method of fitting the known true value with the actual measured value is used to obtain the linear relationship between the true value and the measured value, so as to get the unknown true value through the measured value.
