Abstract

Synthetic aperture radar (SAR) is an established method at radio frequencies for long range and high spatial resolution imaging. Its use in reconnaissance include terrain mapping and object identification. In this report we showcase a ray-tracing engine based on a bounding volume hierarchy (BVH), for generating SAR images. The computation time of the engine is reduced by utilizing NVIDIA Optix, allowing for fast SAR image simulations (appr. 30 s pr. image). The resulting SAR images of armored vehicles closely match those of the MSTAR dataset.
