Abstract This article mainly deal with following topics: presenting an effective solution for the radar to communicate with remote terminals through Ethernet PHY chip and single mode fiber, discussing the system architecture and the communication protocol, and its realization with field programmable gate array. Since the system has such advantages such as high reliability and easy to be implemented, it is to be put into wide usage in RADAR remote communication.
