Figure 5.5. GUI workspace associated with the function Ðmatched_filter_gui.mÑ.

As an example, consider the case where

Note that the compressed pulsed range resolution, without using a window,
is . Figs. 5.6 shows the real part and the amplitude spectrum for
the replica used in the pulse compression. Fig. 5.7 shows the uncompressed
echo, while Fig. 5.8 shows the compressed MF output. Note that the scatterer
amplitude attenuation is a function of the inverse of the scattererÓs range within
the receive window.
