Since location accuracy for low-altitude targets is not good in the Short-Baseline system,a program of the main station off-center of eight-station arrangement is proposed.Firstly factors are analyzed which influence the location accuracy for line-of-sight environments.Then the relationship between main station position and location performance is researched,and a location method for the main station off-center of eight-stations is put forward by increasing the base-station number and layout of the main station off-center,which realizes multiple coverage of the monitoring area using the redundant measurement information by the main station off-center and more base stations provided.Finally the number of base stations and optimal disposition way for low-altitude targets are obtained in the airport by simulating the geometric dilution of precision(GDOP) distribution.Simulation figures and data show that the main station off-center of eight-station arrangement can be achieved over 95% coverage of the airport for low-altitude targets location.
