Abstract

In order to obtain the transmission gain and beam pointing required by the system, the waveform signals in all channels of the radar transmitting system must ensure strict timing synchronization. For the multi-channel digital receiving system, the main factors affecting the synchronization are the synchronization of working clock, the synchronization of system reference signal and the synchronization of data transmission. This paper introduces the design of synchronization system for multi digital sub-array. Time-synchronization module combined with passive distribution module and phase stable cable is used to realize the generation, amplifier and distribution of LO signals, sampling CLK signal. At the same time, the sync trigger signals are generated, delayed and distributed. The synchronization system for multi digital sub-array has strong practicability and engineering reference significance.
