Extended Chirp Scaling with MATLAB - znuerb.com
WebMar 4, 2024 · Typical frequency domain algorithms include range-Doppler (RD) algorithm [9], chirp scaling (CS) [10], and ω−k algorithm. However, each algorithm has its own scope of application [11],... WebGenerate 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: Weband the chirp is 703 points long. Both are zero-padded to a length of 8192 prior to deconvolution to take advantage of the speed radix-2 fft algorithms. (Later we keep 6144 points, which enables one to extract the phase beyond the edges of the original swath. Since the chirp really did interact with the ground outside the digitized swath, this ... devonshire neighborhood columbus ohio
