SAR Scan of Khafre Pyramid Shows Huge Underground Structures

Published on March 25, 2025

Corrado Malanga, from the University of Pisa, and Filippo Biondi, involved in radar and remote sensing research with the University of Strathclyde, published peer-reviewed research in 2022 via MDPI, entitled, “Synthetic Aperture Radar Doppler Tomography Reveals Details of Undiscovered High-Resolution Internal Structure of the Great Pyramid of Giza.”

Their research was conducted using SAR data, Synthetic Aperture Radar, along with proprietary software, developed by Filippo Biondi, that transforms the radar signals into phononic information which allows for the detection of millimetric vibrations. This cutting-edge technology is capable of revealing underground structures invisible to traditional methods, and revealed internal structures never seen before.

Having established their expertise in using SAR to explore pyramid structures non-invasively, a recent press release on their current project was released last Saturday.

This March 15th press release summarized the key findings in the team’s research of the second largest pyramid of the Giza Plateau, known as the Khafre Pyramid. And what they found was astonishing.
