摘要
收发系统间信号隔离度是连续波雷达天线设计的关键指标,它主导着连续波雷达系统的性能。针对本连续波雷达收发天线间具体的信号耦合通道,本文在收发天线间加装扼流槽,铺设微波吸波材料以及安装具有滤波功能的微波光子晶体结构等隔离措施,提高了收发天线间的隔离度。
Signal isolation between transmitting and receiving systems is a key specification of continuous wave （CW） radar, and it defines the performance of CW radar system. Because there is a signal coupling channel between transmitting and receiving CW antennas we designed, in order to improve isolation between two antennas, many measures are token, which include adding choke groove between two antennas, laying microwave absorber, introducing microwave photonic crystal structure with filtering function, etc.
