FIGURE 5.17 Magnitude of the discrete-time Fourier transform of an ideal
moving target slow-time data sequence with F = PRF/4 and M = 20 samples:
D
(a) no window, (b) Hamming window.
Because of the high sidelobes, it is common to use a data window to
weight the slow-time data samples y[m] prior to computing the DTFT or DFT.
To analyze this case, replace y[m] by ω[m]y[m] in the computation of the DTFT
and again use Eq. (5.73) for the particular form of y[m]. Y(F) becomes
