Filippo Biondi, a radar and remote‑sensing scientist who developed a SAR Doppler tomography method, talks about dramatic subsurface scans of Giza. He explains how satellite Doppler tomography images deep tubular and void-like features. The conversation covers validation tests, comparisons with muon scans, detection limits, and potential geological or man-made interpretations.

Episode notes
Scan Geometry Strongly Controls What You Detect
- Detection quality depends on geometry: incidence angle, layover, and whether a tomographic slice intercepts a feature.
- Low incidence (near‑nadir) boosts Doppler sensitivity and deeper penetration but increases layover that can smear pyramid tops.
Reprocess Pyramid Scans With Grand Sasso Level Workflow
- Improve credibility by reprocessing key pyramid scans with the high‑resolution Grand Sasso workflow and publish those focused results.
- Jesse and others urged Filippo to run the same multi‑GPU averaging used on Grand Sasso for Khafre/Khufu.
SAR Scan Corroborated Historic Shaft Under Queen's Chamber
- The team's 2020 scan flagged a shaft under the Queen's Chamber that aligns with historic excavation reports of a pit and chamber system now re‑sealed.
- That correspondence offered one of the clearest archaeological validations for the SAR results.
