With the development of high-speed ADC devices and the increasing performance requirements of radar systems,wideband linear frequency modulation signals have been widely used in radar systems.High-speed sam-pling increases the number of pulse compression points in frequency domain,which in turn increases the processing delay and engineering implementation difficulty.The wideband signals sent from the ADC devices to the FPGAs are in the form of multiphase components extracted in time domain.In this paper,a multiphase method featuring two-dimensional FFT and IFFT based on time domain extraction and frequency domain extraction is implemented.It saves FPGA storage resources and reduces pulse compression processing delay.
