摘　　要：某型箭载相控阵天线在进行系统联试全箭转电过程中出现T/R组件掉电重启的现象,经过分析及试验验证,确认该现象是由于相控阵天线电源滤波电路中的共模电感两绕组匝数不一致,从而没能对系统转电过程中电压变化产生的共模干扰进行有效滤除或抑制,导致电压产生模块重启。通过对共模电感两绕组的一致性分析与试验验证,给出了适应工程化应用的解决方法和加固措施。A certain phased array antenna appears power-off-rebooting of T/R module in the process of system integration of the voltage transfer. After analyzing and testing, we can be sure such phenomenon always in the result of numbers of inductive windings in the phased array antenna unmatched. As a result, common mode interference in the system integration test of the voltage transfer cannot be filtered or restrained effectively. Lastly, voltage makes the mode reboot. Upon consistency analyzing and testing to the inductive winding, we finally propose a solution and reinforcement measures to the engineering application.
