摘　　要：该文基于子空间基本原理,提出了一种天线阵单元间互耦的校正方法,该方法的优点在于校正时允许天线阵同时接收校正信号和待测信号。文中给出的计算机模拟结果证明了这种方法适用于均匀线阵或圆阵以及相干信号源的测向。Basing on subspace principal, this paper provides a calibration approach for mutual coupling among sensors. The benefit of this new method is that calibration signals and unknown signals can be received simultaneously, during the course of calibration. The computer simulation results demonstrate that this approach can be used for uniformly spaced linear or circular arrays and direction-finding of coherent signals.
