Abstract: Various embodiments of the present technology relate to system, methods, and devices for capturing, processing, and rendering synthetic aperture radar data captured by a radar-based imaging system on graphical processing units based on a hive-cell mapping using a tessellation of a Goldberg polyhedron. In some embodiments, SAR data is produced by a radar-based imaging system. A computing apparatus receives the SAR data and associates at least a portion of the SAR data to one or more cells of a Goldberg polyhedron that covers the globe in approximately equally sized hexagonal or pentagonal cells based at least on a location of the SAR data. The computing apparatus provides the portion of the SAR data associated with one or more cells of the Goldberg polyhedron to one or more GPUs, and then processes the SAR data on each of the one or more GPUs to construct images from the SAR data.

Abstract: Various embodiments of the present technology generally relate to systems, methods, and computer-readable media for simulating synthetic aperture radar (SAR) images to be captured by a radar-based imaging system. SAR technology can be used to capture large areas on Earth, from a satellite in space for example, over a single pass. A further pass over the target area can help identify changes in the landscape, scenery, and/or infrastructure providing insight on change detection, temporal analysis, or other measures; however, repeat passes over the target area may have been made from differing angles resulting in artifacts in one or both of the processed images from the two passes. In various embodiments, information about the topology of the target area, and information about the SAR platform's flight path are used to simulate the slant range distortion effects that are to be expected in the SAR image of for that pass.
