许多经典的波达方向估计算法都存在对阵列误差敏感的问题。提出了一种简单有效的在存在幅相误差和互耦误差的情况下进行测向的方法。通过使用一组辅助传感器，可以同时估计波达方向和幅相系数，还可以利用一种新的解耦方法估计互耦系数。该算法不需要迭代运算，也不需要任何校准源或谱峰搜索。仿真结果验证了该方法的有效性。
Many classical direction of arrival (DOA) estimation algorithms suffer from sensitivity to array errors. A simple but efficient method is presented for direction finding in the presence of gain and phase errors as well as mutual coupling errors. By applying a group of auxiliary sensors, DOAs and gain and phase coefficients can be simultaneously estimated, and mutual coupling coefficients can also be estimated by utilizing a novel decoupling method. The proposed algorithm does not require iterative operation or any calibration sources or spectral peak searching. Simulation results demonstrate the effectiveness of the proposed method.
