一种有源相控阵收发通道性能检测方法

A performance detection method of active phased array T/R channels

提出一种相控阵收发通道检测方法。重点研究了检测天线个数选择、通道检测的时间片及时序编排、检测信号的产生和数据传输与处理。该方法在面阵内上方设置检测天线单元,通过与面阵天线单元之间信号耦合来实现检测,能快速对故障通道检测定位。需要的设备量少,经工程验证该方法有效。

A detection method of phased array T/R channels is proposed,and the selection of number of detection antennas,time slice and sequential arrangement of channel detection,and generation,transmission and processing of detection signals are studied.The detection antenna units are installed above the planar array,and the detection is realized through signal coupling between the planar array units and detection antenna units to rapidly detect and locate the fault channels.Less equipment is required,and the method is verified to be effective through engineering projects.
