Paper Abstract

In this paper we will discuss theoretical modeling of laser scattering from complex and large objects. We will describe the main features of scattering cross-section calculation of randomly rough objects, some of its uses and the basis for its validity with different calculation examples. The computation of scattering cross-sections is performed in four steps, mathematical description of the surface, description of electromagnetic and statistical parameters associated with elementary facets representing the object surface, calculation and summation of the backscattered cross-sections from the different elementary facets. Thereby the coherent and incoherent scattering cross-sections of the object are obtained. With this numerical method we can compute resolved and unresolved cross-sections.
