Study on Efficient High Frequency Method of Electromagnetic Scattering of Electrically Large Target

Abstract

In this paper, a new method based on SBR method is proposed to calculate the electromagnetic scattering problem of electrically large target. In traditional SBR method, the split size is usually less than 0.4 wavelength to ensure the accuracy. In this paper, the split size which could describe the shape of the target is enough. So the calculating memory and time can be reduced greatly. And the parallel technology is utilized to further accelerate the speed of the program.
