Biondi validation
Biondi's 'Harmonic SAR' method sits in a genuinely contested technical space: its foundational 2022 Remote Sensing paper is a published, peer-reviewed document, not fringe speculation, yet independent radar specialists argue the single-pass workflow described cannot support the extraordinary subsurface claims extrapolated from it. The validation trail is murky — military and Gran Sasso Laboratory use is claimed but not independently documented. The retraction of the Great Pyramid study and the Khafre controversy have sharpened that ambiguity without resolving it.
Evidence
- The Remote Sensing Great Pyramid paper was subsequently retracted (Newsweek, September 2026), with the Egyptian Supreme Council of Antiquities stating there was 'no scientific evidence' for the alleged structures and that no fieldwork permission had been granted.
- His team's 2022 paper in Remote Sensing — a peer-reviewed MDPI journal — applied the method to the Great Pyramid of Giza and was later extended to claims about shafts, corridors and chambers beneath the Pyramid of Khafre, announced at a 2025 news conference.
- The Miami Herald fact-check (April 2026) noted that no excavation has taken place at the Khafre site and no peer-reviewed study has validated the specific findings there.
- Biondi's team themselves acknowledged that 'only by confirmation on the field' could their hypothesis be validated — a standard that remains unmet.
