Accelerated GRECO Based on a GPU

Accelerated GRECO Based on a GPUAbstract
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.
