Abstract

This paper describes the ducted ocean surface scattering integral equation routine (DOSSIER). DOSSIER is a numerically-efficient high-fidelity numerical model for calculating scattering from partially-submerged targets in ducting environments. The model is based on a hybrid 2D-3D integral equation formulation where the 2D formulation is used to propagate the radar energy to the target location, while the 3D model is used to calculate the backscattered field from the target and its proximity. The combined model effectively accounts for shadowing, multipath, and ducting effects on the effective target reflectivity in such a complex environment.
