Adaptive Supersampling of Rays for Accurate Calculation of Physical Optics Scattering From Parametric Surfaces
Year: 2018
Abstract:
This letter presents an algorithm for supersampling of rays in order to accurately calculate physical optics scattering from parametric surfaces. Based on the differential geometry cal- culus, the algorithm adaptively ...
Reconstruction of Surface Curvature from the Triangular Flat Meshes for the Calculation Radar Cross Section of Electrically Large Objects
Year: 2017
Abstract:
In physical optics prediction of radar cross section, the surface of the object is usually modeled by flat triangular meshes in order to simplify the intersection test and electromag- netic field calculations. This geometrical ...
