摘　　要：雷达和通信系统在系统组成上具有较大相似性,为雷达通信一体化设计提供了可能性。根据全双工通信系统收发同时工作特点,对雷达通信系统常用相控阵天线进行收发隔离分析。提出了收发隔离设计考虑要素,结合案例给出了收发隔离详细计算过程,并推广至多通道相控阵天线收发隔离设计,可用于指导全双工相控阵天线工程设计实现。Radar and communication systems are relatively similar in composition,which makes it possible to integrate radars with communications.According to characteristics of the simultaneous transmit-receive of full-duplex communication systems,the transmit-receive isolation of phased array,frequently used in radar and communication systems,is analyzed in this paper.The considerations in transmit-receive design are presented and combined with a case,the computational process is shown in detail and this computing can be generalized to designs of multi-channel phased array,which provides guidance in engineering application of full-duplex phased array antenna systems.
