摘要
本文提出一种校正阵列通道不一致的新方法,它只需已知一个校正源的方向的大致范围。此方法可用于任意阵几何的阵列,并且适用于较低SNR情况,对阵列通道不一致的误差有相当强的坚韧(robust)性。文中给出了计算机模拟结果。
A new calibration method for array channel mismatching is presented. A rough interval of a single calibration source difection is only known in the method. The method can be applied to arbitrary array geometries and suited to low SNR case. In addition, the method is rather robust for array channel mismatching errors. The computer simulations are given to support the proposed method.
