Abstract
AbstractElectromagnetic scattering characteristics of ground vegetation in a half‐space model are studied. Instead of free‐space Green's functions used in previous literatures, half‐space Green's functions are applied here to solve the scattering fields of a single scatterer. Monte‐Carlo method is employed to build the vegetation over the ground in order to obtain the electromagnetic scattering characteristics of the ground vegetation. Finally, backscattering and bistatic Radar cross sections of the vegetation canopy are calculated. Comparing with the scattering fields obtained by free‐space Green's functions, the scattering fields obtained by half‐space Green's functions are more suitable to describe the electromagnetic scattering characteristics of the ground vegetation.
