摘　　要：阵元间互耦会严重影响阵列的测向性能。文章基于子空间类测向方法，在远场情况下，提出了一种新的阵元互耦有源校正算法。文中的算法是以迭代的形式给出，其目标函数建立在信号子空间性质的基础上，并且适用于多个校正源同时存在的情况。计算机仿真验证了它的有效性，而且可推广至校正源方位估计存在偏差的情况。The mutual coupling errors among array direction finding. In the case of far field sources, nique, a new active calibration algorithm for mutual elements degrade severely its performance of the based on the subspace direction-finding techcoupling errors among sensors is presented. The algorithm is given in iterative style, and its target function is built on the properties of signal subspace. It is suitable for the different calibration sources exist at the same time. The simulation resuhs are presented to demonstrate the validity of the proposed method, and it can be extended to the situation that the azimuth estimations for calibration sources have deviations.
