This academic article by Filippo Biondi and Corrado Malanga, **employs a novel method of Synthetic Aperture Radar (SAR) Doppler tomography** to investigate the **internal and external structures of the Great Pyramid of Giza and other pyramids on the plateau**. The authors **analyze micro-movements induced by seismic waves** to create **high-resolution 3D tomographic images**, revealing **previously undiscovered internal features** and suggesting an **eight-sided structure for all three main Giza pyramids**, further proposing a **functional interpretation of the pyramid's internal architecture** based on these findings.
