Research on high frequency prediction of double reflection combined with GPU parallel technique

Compared with the numerical method, the high frequency approximation algorithm is efficient and fast in solving the problems of electrically large complex target. Due to the calculation of secondary scattering field component in the high frequency algorithm for complex electrically large target very time-consuming, it is necessary to research a accelerating algorithm. The application of GPU parallel technique is proposed to accelerate high frequency prediction of double reflection. The experimental results indicate that the results of RCS accelerated are in good agreement with the results of the exact solutions.
