I am trying to apply a window function to a linear chirp. When I look at each signal, there seems to be no difference between the chirp signal and the windowed-chirp signal. Why is this? My aim is to undertake pulse compression then move on to doppler processing. I also want to zero-pad the signal either side but I cannot add the zeros to the end of the signal only overlay and extra signal.
How do you apply the window function and zeroo-pad to a chirp/linear chirp?
