Abstract: This paper designs a two dimensional pulse compression processing system by using the embedded processor MicroBlaze in FPGA as the control kernel. Two realization architectures of pulse compression are presented according to the resource assignment conditions in FPGA. DDR SDRAM controller implemented by FPGA realizes matrix transposition processing efficiently by using matrix partition linear mapping method. A simple SAR imaging processing is simulated, and its result proves the validation of the system.
