WebIn 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 … WebThese micro scale movements produce additional Doppler shifts, referred to as micro-Doppler effects, which are useful in identifying target features. This example shows two applications where micro-Doppler effects can be helpful. In the first application, micro-Doppler signatures are used to determine the blade speed of a helicopter.
