N2 - Pulse compression is an indispensable processing technique for improving resolution in radar systems, and the general processing method for pulse compression is to complete fast Fourier transform (FFT) and other processing in an embedded processor, save the data in memory, and then complete data reading, imaging, and other processing by data processing software, Unable to achieve real-Time processing of Frequency Modulation Continuous Wave (FMCW) signals. In this paper, a real-Time pulse compression processing technology of FMCW signal field programmable gate array (FPGA) is proposed. First, the programmable logic (PL) end of FPGA receives data to realize zero filling, window function addition, pulse compression and scene interception processing in parallel pipeline mode, Finally, the processing results are transmitted to the upper computer through a gigabit network based on the User Datagram Protocol (UDP) protocol on the PL end and displayed in real-Time. The experimental results show that the proposed data processing method can process 8192 data in 0.26 milliseconds, achieving real-Time FMCW signal processing.
