In this paper, an efficient and robust localization algorithm using Receiver Signal Strength Difference (RSSD) for a noncooperative RF emitter is given. The proposed algorithm firstly calculate the center point and radius of Apollonius’s circles and then estimate the intersection point of the circles based on Time of Arrival concept. And this paper also compares the performance of RSSD localization algorithms such as Non-linear Least Squares and Linearized Least Squares by Lines of Position (LOP) with the proposed algorithm. And some conclusions have been reached regarding the relative accuracy, robustness and computational cost of these algorithms. KCI Citation Count: 0
