#17 - Giza Pyramid Scans Explained | Dr. Filippo Biondi & Dr. Armando Mei

What’s really under Giza? In this episode of the Ancient Technology Podcast, Karoly sits down with Filippo Biondi (satellite/SAR specialist) and Armando Mei (Giza researcher) to translate the buzz around pyramid “scans” into plain English. We break down how satellite synthetic aperture radar (SAR), muon tomography, and seismic methods actually work, what they can (and can’t) see, and how new processing pipelines can surface hidden structures and water signatures beneath the Giza Plateau.Filippo explains measuring resonance and micro-movements from space (Doppler/phase analysis) and how those techniques adapt to ancient monuments. Armando walks through site alignments, long-standing hypotheses, and why detector placement matters for the well-known “big void” above the Grand Gallery. Together we compare signals reported at Khufu (Great Pyramid), discuss targeted scanning around Khafre and the Sphinx, and outline a practical roadmap for future surveys—minus the hype.Filippo Biondi's website: https://www.harmonicsar.com/Armando Mei on youtube: https://www.youtube.com/@ArmandoMeiCosmic Summit presentation of Filippo and Armando: https://cosmicsummit.live/content/dr-filippio-biondi-armando-mei🎧 Check Out Other Episodes: ⁠⁠⁠https://www.youtube.com/playlist?list=PL5w7ZZHKlr0Ro64uA-ZH3uvSNyzsCKO57⁠⁠⁠🙏 Support Links:Join this channel to get access to perks: ⁠⁠⁠https://www.youtube.com/channel/UCTgM_Z6LX9upwutrJveOPSA/join⁠⁠⁠Patreon: ⁠⁠⁠https://www.patreon.com/ancienttechnologypodcast⁠⁠⁠PayPal tip jar: ⁠⁠⁠https://paypal.me/ancienttechnology⁠⁠⁠Revolut tip jar: ⁠⁠⁠https://revolut.me/krolybsy1u⁠SHOW NOTES:0:00:00 - Intro0:03:28 - How did the research begin0:06:16 - How the satellite Doppler method works0:08:30 - Hidden chambers in the Great Pyramid0:13:12 - How the SAR measurements work0:17:35 - Physics & astronomy correlations (Sphinx, Orion, precession)0:23:49 - How can we see underground0:34:17 - Underground pillars & network across Giza0:42:21 - Validation tests; tunnels, water & Osiris shaft0:49:17 - Tools & processing (Matlab, CPU vs GPU)0:50:24 - Next sites to scan0:53:54 - Tunnel under the Sphinx0:54:57 - Other interesting sites0:57:40 - ScanPyramids and muon scan comparison1:07:15 - Scanning depth limits & future system1:10:59 - Team1:12:22 - Debunkers
