Development of Parallel Algorithms for Calculation of Backscattering Characteristics of Complex Shape Objects
Abstract— A programming technique, which is carried out using the Open Multi-Processing
(OpenMP) library and can be employed to assess scattering fields from electrically large complex
shape objects, is developed and presented in this paper. The basic idea is to employ the OpenMP
library to accelerate paths tracing for physical optics (PO) and shooting and bouncing rays (SBR)
methods. The procedure of OpenMP-based paths tracing is divided into two steps, which are
shadow faces removal and reflected rays searching. In addition, OpenMP speedup scheme has been
proposed to improve the efficiency of PO algorithm.
Index Terms— scattering field, physical optics, radar cross section, Open Multi-Processing (OpenMP)
library, parallel algorithms.
