摘　　要：阵列天线在通信领域应用非常广泛,常规的收发隔离技术只是针对一路信号进行回波信号的抑制,假如套用常规方案对阵列天线的每一路输入进行一次自适应抵消将会大量消耗硬件资源,在实际操作中是不可行的,提出一种运用并行延时方案对16路输入的阵列天线进行回波信号抑制工作。利用这种并列式的结构可以有效的减少硬件消耗。The array antenna is widely applied in communication field. A group of antenna will have lots of input, while the self-excited phenomenon is objectively existed. The conventional way only works on a single role. It will consume lots of hardware resources to filter each role of array antenna with a single filter so that it is unavailable. This paper proposes a scheme to use parallel delay on 16 road input array antenna which will cancelling the echo signal. It will effectively reduce the hardware resources when this parallel structure is used.
