Backscattering of Electromagnetic Waves from a Surface Composed of Two Types of Surface Roughness

摘要

The report presents a vector theory for the backscattering of electromagnetic waves from a random, rough surface. The basic technique used is that employed by Dr. Adrian K. Fung in an earlier work. The surfaces used in the report are those that are generated by a stationary gaussian random process as opposed to surfaces generated by a random array of objects. The former type of surface is assumed to simulate many of the vegetation-free sections of the earth. It is important to understand the basic characteristics of scattering from such surfaces for the purpose of aiding military geographic analysis by radar. (Author)
