In a receive mode, either the sumchannel or a difference channel of the panel combiner is chosen as the active channel.
在接收方式下，选择面板组合器的和通道或差通道作为工作通道。

We analyze the pattern function of DBF in 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。
