FIGURE 4.10 (a) Zero-Doppler cut of simple pulse AF, (b) zero-delay cut.

A Doppler mismatch not only reduces the peak amplitude but, if severe
enough, completely alters the shape of the range response of the matched filter.
Figure 4.11 shows the effect of varying degrees of Doppler mismatch on the
matched filter range response. These curves should be compared to Fig. 4.10a.
A mismatch of 0.31/τ Hz results in a reduction of about 16 percent in the peak
