This dataset contains the image data used in our study on PRNU-based source identification for pushbroom satellite imagery. It includes a curated subset of Sentinel-2 Level-1B (L1B) products together with a natural image dataset used as a reference benchmark. The data are organized by sensor/detector to enable reproducible experiments in source attribution and forensic analysis. The Sentinel-2 L1B images preserve native detector geometry and are provided without additional geometric correction. They are intended for research on acquisition-aware forensic methods, sensor fingerprinting, and consistency verification in remote sensing imagery. This dataset is released to support reproducibility of the experiments reported in the associated publication and to encourage further research in satellite image forensics.
