Bidirectional SAR Imaging Mode [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2013 This paper introduces the bidirectional synthetic aperture radar (BiDi SAR) imaging mode, i.e., the simultaneous imaging of two directions by one antenna into one receiving channel, and presents short-term time series of images and interferograms acquired by the TerraSAR-X and TanDEM-X satellites.

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.

Sar2color: Learning Imaging Characteristics of SAR Images for SAR-to-Optical Transformation
Remote Sensing, 2022 Optical images are rich in spectral information, but difficult to acquire under all-weather conditions, while SAR images can overcome adverse meteorological conditions, but geometric distortion and speckle noise will reduce the quality of SAR images and thus make image interpretation more challenging.
