A now-retracted 2022 Remote Sensing paper led by Filippo Biondi, with Curado Malinga and Filippo Bendandi among the coauthors, used COSMO-SkyMed radar data to analyse tiny movements of the Great Pyramid's surface caused by seismic waves. The authors argued that repeated satellite observations enabled a full 3D tomographic reconstruction and claimed to reveal previously undetected internal structures. The radar detected surface vibrations rather than penetrating the stone. The journal has retracted the paper, leaving those interior-structure claims unestablished.
Retracted paper claimed SAR tomography mapped Great Pyramid interior

Key facts
- The 2022 Remote Sensing paper was led by Filippo Biondi, with Curado Malinga and Filippo Bendandi as coauthors.
- Remote Sensing has retracted the paper, so its claimed full 3D image of the pyramid's interior is not an established result.
- The method used COSMO-SkyMed synthetic-aperture radar data to measure tiny surface movements caused by ambient seismic waves; it did not directly penetrate the pyramid.
- Repeated satellite acquisitions at different viewing geometries were used in the proposed Doppler-tomographic reconstruction.
- COSMO-SkyMed is Italy's second-generation X-band SAR satellite constellation.
