Research on MS Setover Location Method with LOS on Multilateration
Abstract:
Location accuracy for low-altitude targets is not well in Short-Baseline system. A program of main station off-center of eight-station arrangement is proposed. Firstly analyses factors influencing the location accuracy for line-of-sight environments. Then researches the relationship between main station position and location performance, put forwards a location method of main station off-center of eight-station by increasing the base-station number and layout of the main station off-center which realizes multiple coverage of monitoring area using the redundant measurement information by main station off-center and more base stations provided. Finally gets the number of base station and optimal disposition way for low-altitude targets in the airport through simulating geometric dilution of precision (GDOP) distribution. Simulation figures and dates 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.
