FPGA is used to realize radar digital pulse compression, which overcomes the problems of limited processing speed and poor real-time performance of DSP. Based on the PCI radar signal processing platform developed by ourselves, the principle and process of realizing digital pulse compression based on FPGA is introduced, in which an optimal design on the filter for digital pulses is studied to solve the problem of the limited resources in FPGA. The advantages of using FPGA in digital pulse compressionare are shown by the simulation results , which supplies a new method for the implementation of radar digital pulse compression.
