一种新的互耦校正方法在均匀圆阵中的应用

Application of a new calibration approach for mutual coupling in the uniformly spaced circular arrays

讨论了一种新的用于阵元间互耦校正的方法,它的优点是只需要一个辅助校正信号源,并且它的方向可以是未知的,这种方法可以使得测向算法的分辨率得到明显提高,并将这种方法应用于均匀圆阵,计算机的仿真结果证明了这种方法的优越性.

A new calibration approach for mutual coupling among sensors was discussed. The benefit of this method is that only one added signal is needed and its angle may be unknown. The method could improve the resolution of direction- distinction algorithm. The paper applied this method to the uniformly spaced circular arrays and the computer simulation results proved the superiority of the method.
