Abstract:

The FPGA is used to realize the calculation of absolute value,video integration and CFAR detection of radar video signal. This technique can overcome the problem on limited processing speed, poor real time performance of DSP. The principle and course of calculating absolute value, video integration and CFAR detection algorithm based on FPGA are introduced. The advantages of FPGA are shown by simulation results of radar signal processing.
