Abstract
In this paper, we propose an effective method to estimate the target location using two receiver stations and bi-static geometry. In this method, the least squares criterion-based optimization problem is formed using a combination of the time difference of arrival (TDOA) and angle of arrival (AOA) measurements to estimate the target location. This problem is solved by semi-definite relaxation without requiring an initial estimation of the response or comprehensive search. The proposed method can effectively localize the target location with high accuracy in the presence of high noise level and, consequently, inaccurate TDOA and AOA measurements of the input signal. The numerical results show that the proposed method estimates the target location more accurately than some state-of-the-art methods in the presence of inaccurate input parameters.
