The detection and recognition of moving target is focused by lots of research schol- ars greatly. However, the algorithms for detection and recognition have to be tested and verified by a great deal of radar echo data. Efficient electromagnetic scattering simulation becomes an effective and economic method for achieving it. The design of appropriate moving target elec- tromagnetic scattering simulation for computer-generated bots poses serious challenges as they have to satisfy stringent requirements that include computation and execution efficiency. This paper discusses a novel efficient high-frequency electromagnetic scattering simulation approach of the rotating moving complex targets. Based on the wide-adopted high-frequency asymptotic methods, such as Physical Optics (PO), Equivalent Edge Current (EEC) and Shooting Bouncing Ray (SBR), a novel efficient approach is proposed by employing the adaptable NVIDIA OptiX ray-tracing engine to solve scattering problems of rotating moving complex targets. High accu- racy and efficiency of the hidden-surface-removal (HSR) in PO/EEC and the ray-tracing in SBR are realized at the same time with the state-of-art GPU computation technology. The precise scattering modulation effects of rotating moving target are therefore achieved. Experiments show the effectiveness of the approach.
