Chirp scaling algorithm matlab code
WebMar 1, 2013 · Chirp-scaling algorithm employs the property of the transmitted signal, whose range frequency is linear variant. A scaling function is multiplied with the signal to eliminate the space variance of the RCM curves of the targets in different range gates in range-Doppler domain [ 22 ]. WebA chirp gives a good visual of the low-pass filter action of passing the low frequencies and attenuating the high frequencies. f_chirp = 1/16; % Target frequency x_chirp = sin (pi*f_chirp*t.^2); % Linear chirp titles = { 'Impulse', 'Max output', 'Sum of sines', 'Chirp' }; x = [x_impulse, x_max_output, x_sines, x_chirp]; Call Original Function
