SAR-SIFT: A SIFT-Like Algorithm for SAR Images [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2015 The scale-invariant feature transform (SIFT) algorithm and its many variants are widely used in computer vision and in remote sensing to match features between images or to localize and recognize objects. However, mostly because of speckle noise, it does not perform well on synthetic aperture radar (SAR) images.
