Realization of FPGA Remote Configuration of T/R Modules for Digital Array Radar
LI Dong-fang · Radar Science and Technology · 2011
Digital array radar(DAR) becomes an important development direction of phased array radar.The digital array T/R module(DAM) is the core of DAR.Digital array radar has a large number of DAM modules,which are usually integrated with the array antenna and installed outside the aircraft.This results in difficulties in debugging.A design method for FPGA remote updating and configurating files is presented in this paper.Flash memory is used to store configuration data and CPLD device to generate FPGA configuration timing and multiplexing the optical fiber,which solves the problem of remotely debugging the DAMs.The dynamic reconfiguration technology has greatly improved the efficiency of the system test.It has been successfully applied in a demonstration project of digital array radar and achieves good results.
