| Abstract: | Ranging theory of FM/CW radio fuze is introduced. The Discrete Fourier Transform （DFT） application in proximity fuze signal processing is analyzed. An implementation scheme of optimized points Fast Fourier Transform （FFT） algorithm is given and tested successfully through the TM2320VC5416 DSP experiment system. The test result is accordant with the theory value. The result shows that the optimized algorithm is valid and viable to extract the frequency information of FM/CW radio fuze, which is used in fuze signal processing system and in other real-time situation. |
