Unmanned aerial vehicle (UAV) synthetic aperture radar (SAR) image characteristics, such as large geometric distortions, striped inhomogeneous radiation, severe speckle noise and ultra-high resolution, pose significant challenges to multi-view UAV SAR image registration. To address these issues, we propose a robust multi-view UAV SAR image registration algorithm based on the selective correlation of the log gradient descriptor. First, slant range UAV SAR images are geocoded using a publicly available digital eleva…
