To smooth out the sidelobes after matched filtering, apply a window to the transmitted pulse before time-reversing. The steps in the previous section were shown to better visualize the process of matched filtering in the frequency domain. The function fftfilt can quickly apply matched filtering to a function.

WebOct 3, 2013 · 1 Answer. Your fft command is wrong. The second argument is the FFT length, not the window. Y = fft (X,n) returns the n-point DFT. fft (X) is equivalent to fft (X, n) where n is the size of X in the first nonsingleton dimension. If the length of X is less than n, X is padded with trailing zeros to length n. If the length of X is greater than n ...
