Generating high resolution SAR image of an object typically requires its scattered field data over a large number of aspect angles and frequencies, which is very time consuming to obtain. This paper discusses the implementation of the PO-SBR method on GPU to efficiently compute the massive scattered field data required for SAR application.
The physical optics-shooting and bouncing rays (PO-SBR) method is very efficient for the prediction of electromagnetic scattering of electrically large objects. With OptiX, a graphics processing unit (GPU) ray-tracing library, the authors have optimized PO-SBR method for single frequency. However, another typical application to synthetic aperture radar (SAR) requires numerous frequency points. This...
In this paper, the surface-wire integral equation combined with the Precorrected-FFT method is used to solve antenna radiation problem. The code is further parallelized to harness the power of graphics processing units (GPUs). The parallel algorithm on GPU is described and the code flow is shown. Test result is given to demonstrate the correctness of the code and benchmark is conducted to show the...
