Abstract :
This paper puts forward that FPGA plays more and more important role in storage and pretreatment of SAR signal with its rapid development and its powerful parallel processing ability. Further more, taking a typical SAR signal processing system as an illustration, in this system, FPGA is designed with modularization method. Of all these modules, this paper emphasizes SDRAM controller module which manages and controls 2GB SDRAM memory space, filtering and down-sampling module which has the function of filtering and down-sampling at the same time.
