Modeling of high-frequency scattering from objects using a hybrid Kirchhoff/diffraction approach.
In this paper a numerical discretization and transformation into the time domain of a hybrid Kirchhoff/diffraction method is presented for the modeling of high-frequency pulse scattering from rigid bodies. A series of benchmark cases, for smooth and rough spheres and cylinders, is presented to establish the accuracy of the method in the time domain.
