| Summary: | An efficient demodulation method
designed for FMCW (Frequency-Modulated Continuous Wave)
radar is presented. It is a kind of modified DFT (IDFT) algorithm;
the spectrum segment of interest can be easily extracted from
the original signal without calculating the whole DFT/FFT. It
provides fast demodulation and extraction of desired frequency bands in our HFSWR (High-Frequency Surface Wave Radar)
system. The proposed approach enhances the performances of
radar system and reduces the computing complexity. The new
structure could also be inversely used for signal modulation. And
also arbitrary sampling rate conversion could be achieved with
the combination of forward and backward structure. |
