Scattering from Foliage Covered Terrain.
Abstract
A brief review of efforts directed toward modeling the effects of foliage covered rough terrain on electromagnetic scattering is presented. A two-way passage approach is proposed as an approximate method of solution. In this approach, an incident field is transmitted through a foliage layer in free space. The field transmitted through the foliage acts as an incident field upon the rough surface. The field scattered by the surface is taken to be a secondary incident field upon the foliage slab. The net scattered field is the sum of surface scattered field and the two fields scattered from the foliage. Although the Foldy-Twersky theory can be used to account for the propagation through the foliage, investigations of the method of smoothing are also being carried out. The method of smoothing is also proposed for use in the surface scattering part of the problem. Particular attention is directed toward the asymptotic evaluation of the first interaction terms in this formalism. Keywords include: Electromagnetic scattering; Rough surface scattering; Applied probability theory; Multiple scattering; Method of smoothing; and Random boundary value problems.
