Equation (4.51) is plotted in Fig. 4.8 in a three-dimensional surface plot
and in Fig. 4.9 as a contour plot, which is often easier to interpret and is
therefore used in most cases in the remainder of this chapter. The AF for a
simple pulse is a triangular ridge oriented along the delay axis. Doppler
mismatches on the order of 1/τ Hz or more drastically reduce and spread the
matched filter output peak, as was shown previously.
