Research of influences from typical scene parameters on target and rough surface composite electromagnetic scattering characteristics

Some studies of the influences from typical scene (target, rough surface) parameters on the target and rough surface composite electromagnetic scattering characteristics are carrying out. The target and rough surface with specific type and spectrum cases are considered. The composite scattering integral equations are built. The numerical hybrid strategies, such as the Propagation-Inside-Layer-Expansion (PILE) combined with the Forward-Backward Method (FBM) scheme, etc., are applied. The influence from different target parameters, such as, size, depth, etc., to the coupling inductions is investigated. The influence from different rough surface parameters, such as rms height, correlation length etc., to the composite scattering is implemented. The experiential and prediction models between typical scattering phenomenon and coupling interaction mechansium under different parameters can be built and analyzed. The presented studies will make considerable sense to the fields of electromagnetics, remote sensing, optics, radar surveillance, target recognition, material science, etc‥
