dc.description.abstractThis paper addresses two graphical processing approaches for computation of edge scattering with Physical Theory of Diffraction (PTD) high-frequency approximation. One is based on processing only a bitmap containing an image of the radar target, while the other uses a bitmap graphical processing algorithm to identify illuminated and shadowed facet mesh vertices, published in 2014, and then computes PTD diffraction coefficients for illuminated edges in the conventional way. The first approach is much faster for models containing a very large number of facets, but introduces pixel discretization noise, that can be alleviated by using larger bitmaps.
