Polarimetric RADARSAT-2 and ALOS PALSAR multi-frequency analysis over the archaeological site of Gebel Barkal (Sudan)

Multi-frequency polarimetric analysis using RADARSAT-2 and ALOS PALSAR satellite data reveals subsurface structures at the UNESCO World Heritage Site of Gebel Barkal, Sudan. The study demonstrates that C-band and L-band radar signals can penetrate soil to detect archaeological features, offering a non-invasive method for identifying subsurface anomalies. These findings highlight the potential of integrating polarimetric SAR (polSAR) with optical satellite data in GIS-based projects to support archaeological research and conservation efforts, particularly for at-risk sites. Collaborations between universities in Turin and Venice enhanced the study's methodological rigor.
