The method can correct the mismatch inside a channel and among channels, and is also suitable for both DBFin array element and DBFin non-uniform subarray.
该方法可对通道内和通道间的失配进行校正，且对由阵元构成的DBF和子阵d BF均适用。

We analyze the pattern function of DBFin subarray under the ideal condition and with channel mismatch, and give the pattern functions of sum and difference beam.
本文分析了子阵d BF在理想通道条件及通道失配情况下的方向性函数，给出了其和差波束方向性函数特性。
