摘要

本文利用现代图形加速卡中GPU(Graphics Process Unit)的可编程管线

实现了图形电磁计算(GRECO)方法.与原有的方法相比

在利用物理光学和物理绕射理论的基础上

计算速度提高了20倍左右.并且利用GPU实现了射线追踪算法

用于目标上多次散射的计算

使得GRECO方法可以快速计算具有凹腔结构目标的电磁散射.本方法对于目标识别和逆合成孔径成像等方面的研究具有重要的应用价值.

Abstract

For obtaining the electromagnetic scattering characteristic of a complex target efficiently

GRECO (Graphical Electromagnetic COmputing) is implemented by a programmable pipeline of a modern GPU (Graphics Processing Unit).The speed of the simulation can be improved up to 20 times compared with the raw GRECO.The ray tracing algorithm based on a GPU is implemented to obtain the multiple reflection contribution of a target with concave structure.This approach will redound to research works such as radar target identification and inverse synthetic aperture radar (ISAR) imaging.
