Deep Learning Enhances Sentinel-1 SAR Imagery Using Azimuth Doppler Decomposition

Researchers have developed a novel self-supervised deep learning framework to enhance Sentinel-1 Stripmap (SM) Synthetic Aperture Radar (SAR) imagery. This method utilizes azimuth subaperture decomposition to create paired training data without requiring external sensors or simulated ground truth. The framework integrates single- and multi-frame learning with an iterative refinement process, outperforming existing baselines like MERLIN in structural fidelity while offering a trade-off in speckle smoothing.
