Toward a theory of ultrawideband sea scatter

In this work the problem of developing a theory of sea scatter for ultrawideband electromagnetic waves is examined (with special application to radar). The motivation for this work derives from the work of Wetzel, who formulated a scalar, time-domain model of sea clutter and showed that the local curvature properties of the rough surface are an important factor in determining the sources of the scattered return. Here, Wetzel's result is extended to the electromagnetic problem and then extended further to obtain some polarization effects consistent with the small perturbation method.
