The chirp signal

網頁2016年3月12日 · This study presents an innovative algorithm to extract binary data from a high frequency linear chirp signal contained in wideband radar pulse signal. The algorithm is designed for chirp signals (bandwidth of 125 - 1375 MHz) with a maximum chirp rate of 750 MHz per 100 ns and a maximum chirp range equivalent to the signal bandwidth. … 網頁Generate a signal consisting of a chirp sampled at 1.4 kHz for 2 seconds. The frequency of the chirp decreases linearly from 600 Hz to 100 Hz during the measurement time. fs = 1400; x = chirp (0:1/fs:2,600,2,100); stft Defaults Compute the STFT of the signal using the spectrogram and stft functions. Use the default values of the stft function:
