Signal synchronization is a key technology of digital T/R modules in phased array radar.In view of the problem that the phase change of synchronization clock signals of multiple channels in T/R modules at high and low temperatures disables signal synchronization,this paper proposes a method that can automatically compensate the phase errors of clock signals at high and low temperatures.The proposed method does not require real-time control of the compensation values.In addition,it features simple circuit layout.The proposed method shows remarkable performance during batch production of a radar.It has high application value.
