Abstract :
This paper contains the spaceborne synthetic aperture radar signal processing with large amounts of data, large memory capacity and other characteristics, it analysis the function of the signal processing system, a method of using FPGA to reduce the range sampling filter, solves controlling 2 GB SDRAM memory of FPGA, and implements a isomerous system of a high-performance floating-point DSP and a large scale FPGA.
