Abstract :
Based on the modified TOA and AOA measurements, a weighted least square (WLS) scheme to estimate the target location in the TRM multistatic radar system is proposed in this paper. The performance of the location estimation scheme is evaluated according to the basis of the root mean square error (RMSE). In the proposed scheme, all the measured errors including the measured azimuth angle, the measured elevation angle, and the measured range from the sum of the distance for transmitter-to-target and the distance for target-to-receiver are considered. The performance of the proposed scheme is given under the cases of the bistatic radar system and the TR4 multistatic radar system, respectively.
