Modeling of Forward Scattering
Abstract
Since forward scattering should be best simulated with a point- scatterer model through the use of specular point theory, a derivation of the theory from the Helmholtz integral formulation is presented and attendant approximations noted. All hold reasonably well for most cases of interest, and produce only minor errors with respect to exact results. Several implementation issues are discussed. A simple way to realize the point-scatterer model is through the partition of the surface into correlation areas and the probabilistic assignment of specular points. Detailed examination of ping-to-ping fluctuations, or the effects of higher order statistics, requires generation of surfaces with a desired roughness spectrum. A procedure to realize this is presented.
