Fig. 2.10 shows a plot of the probability of detection as a function of SNR
for and for both Swerling I and V type fluctuations. Note
that it requires more SNR, with fluctuation, to achieve the same as in the
case with no fluctuation. This figure can be reproduced using MATLAB pro-
gram Ðfig2_10.mÑ given in Listing 2.17.
