The log-normal has both the narrowest peak and the longest tail of any of the

distributions shown for this choice of parameters. Unlike all of the others, the
exponential does not have a distinct peak near the mean RCS. Each of the others
does have a distinct peak, making them suitable for distributions with one or a
few dominant scatterers.

One fundamental difference among the various RCS models of Table 2.3 is
