arXiv:2606.20523v1 Announce Type: cross Abstract: Multimodal foundation models have advanced rapidly thanks to large optical benchmarks, but comparable resources for synthetic aperture radar (SAR) remain limited. Existing SAR--optical datasets largely rely on low-resolution, intensity-only Ground Range Detected~(GRD) products and do not preserve complex-valued SAR measurements or native acquisition geometry, which restricts physically grounded multimodal learning. In particular, large-scale public datasets combining very-high-resolution (VHR) SAR SLC, aligned optical imagery, and natural-langu
The rapid advancement of multimodal foundation models is pushing the demand for higher-fidelity and more diverse datasets, making this new SAR-optical benchmark timely.
This new dataset addresses a critical gap in high-resolution, complex-valued Synthetic Aperture Radar (SAR) data, enabling more sophisticated and physically grounded multimodal AI development.
The availability of SARLO-80 will accelerate the development of AI applications in areas leveraging very-high-resolution SAR, particularly for intelligence, surveillance, and reconnaissance.
