The Microwave Scattering and Absorption Characteristics of Vegetation
|
Abstract:
In passive microwave remote sensing, the vegetation layer within a footprint is of great diversities and anisotropy. Under lower frequencies the vegetation effect could be obtained by statistical average of the scattering and extinction characteristics of single scatter. In this paper the scattering calculation methods of an arbitrary scatter are discussed, where Raleigh-Gans theory is used for disc and needle, and infinite length approximation theory is employed for cylinder. Regarding the extinction of every kind of scatter, the results of the sum of scattering and absorption coefficient, and that from forward scattering theory are compared and discussed.
