| Abstract: | There were some disadvantanges when the fast maneuverable target was intercepted with filter groups.A method of obtaining target radial velocity by picking up the Doppler shift with FFT for the echo was presented.The radix-4 FFT arithmetic principle was introduced.The implement method of FFT was given out with FPGA. |
