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.

在本文中，我们提出了一种使用两个接收站和双静态几何来估计目标位置的有效方法。在该方法中，使用到达时间差 (TDOA) 和到达角 (AOA) 测量值的组合来估计目标位置，从而形成基于最小二乘准则的优化问题。这个问题是通过半定松弛解决的，不需要对响应进行初始估计或全面搜索。在存在高噪声电平的情况下，所提出的方法可以有效地以高精度定位目标位置，从而导致输入信号的 TDOA 和 AOA 测量不准确。数值结果表明，在存在不准确输入参数的情况下，所提出的方法比一些最先进的方法更准确地估计目标位置。
