Electromagnetic Scattering from Target Buried in Layer of Randomly Distributed Trunks

摘要

Electromagnetic scattering model for two adjacent trunks and deterministic target(sphere) above a rough surface ground plane was analyzed by using the reciprocity theorem and the image theory. The finite-length multi-layer dielectric cylinder was used to model the trunk. The iterative algorithm and spherical vector wave function were used to calculate the scattering amplitude matrix of the finite-length multi-layer dielectric cylinder and sphere respectively. The validity of the method was checked by numerical computations based on the moment method. Finally, the influences of the bark layer and the roughness of the surface on the scattering pattern of target(sphere) are also discussed at L band, C band and X band.
