英文摘要：

Based on CPCI bus,a radar signal processing board was designed and implemented with FPGA,which can be used to accomplish the general functions for radar signal processing like DDC,pulse compression of large time-bandwidth pro-duct signals in time-domain and FFT. At last,DDC and the pulse compression of large time-bandwidth product signals in time-domain are realized according to the requirements of some radar signal processing systems. The test results prove the effective-ness of the system.
