摘　　要：针对超分辨测向中应用得最为普遍的均匀线阵和均匀圆阵天线 ,基于子空间基本原理 ,提出了一种阵元间互耦的校正方法。该方法的优点在于只需要一个辅助校正源 ,并且它的方向可以未知。Based on subspace principle, the paper provides a calibration approach for mutual coupling among sensors of uniformly spaced linear arrays and circular arrays, which are widely used in superresolution direction finding. The benefit of this new method is that only one calibration signal is needed, whose angle may be unknown. The computer simulation results demonstrate that this approach is correct and effective.
