  A phenomenological description of diffractive dijet hadroproduction via
double Pomeron exchange is presented. This description is based on a modified
version of the Ingelman-Schlein model which includes the evolution of the
Pomeron structure function and corrections regarding rapidity gap suppression
effects. The same quark-dominant Pomeron structure function employed in a
previous report to describe diffractive dijet and W production via single
Pomeron processes is shown here to yield results consistent with the available
data for double Pomeron processes as well.
