This paper designs the on board SAR real time imaging processor using seven piec es of Xilinx FPGA,which consists of four parallel process units,one CS factor unit,one SDRAM controller unit and one control unit.The system combines pipelin e process and parallel process to reduce process time,also combines fixed-point operation and floating-point operation to reduce hardware resource.This system can make image within 33 seconds when works in 100MHz,and the imaging quality c an fit for the requirement by testing with the Radarsat raw data.
