In this paper, a method to improve the accuracy of the time of arrival position location (TOA-PL) solution in multistatic radar systems is proposed. In the conventional TOA-PL technique, the least square (LS) method is applied to estimate target location. However, the performance of the method is significantly degraded under wrong measured data (called as the great error) at the receiver. Hence, the accuracy of location estimation needs to be improved. In this paper, a scheme is proposed to eliminate the effect of the great error. The performance of the location estimation is evaluated based on the root mean square error (RMSE). The results show that the performance with the proposed scheme is better than that with the conventional scheme. ? 2012 IEEE.
