  • Abstract
    In this paper, modulation parameters as modulation bandwidth and type are extracted by using the shape features of the time-frequency domain of the frequency modulated continuous wave radar (FMCW) signals. Time-frequency image of the received signal is obtained by taking short time fourier transform (STFT). Then Hough transform (HT) is applied to the binary image which is obtained after thresholding. Modulation parameters are determined after the evaluation of the one dimensional modulation vector. The result of the parameter extraction at different SNR values and modulation types is presented.
