Abstract

A weighted fusion location method based on multilevel fault-tolerant mechanism is proposed to solve the problems of range relay test, real-time outlier elimination and false target tracking by a few equipment. Through the application of multilevel fault-tolerant algorithm, the target position can be calculated normally without identifying and eliminating the outliers of the measured data and the false targets of a few devices in the preprocessing stage. The weighted fusion positioning method is used to further improve the measurement accuracy. The simulation results show that the proposed method has a good fault-tolerance capability for the measured data, which can not only make full use of the measured data of photoelectric theodolite, but also perform positioning calculation and false target identification without outage elimination, so as to ensure the reliability of positioning results. In the process of changing target position and data source, the measurement data can be automatically selected for fusion processing, and the trajectory switching is smooth, which meets the requirements of relay measurement. At present, the proposed algorithm has been applied in a real-time fusion processing system of a shooting range, and has realized the accurate guidance of the photoelectric theodolite station that failed to capture and track in multiple measurement tasks
