Real acquisition · volume rendering
What the method puts
beneath the ground.
These are the actual depth volumes produced from one ICEYE Spotlight Dwell Fine acquisition of the Giza plateau on 27 August 2025. The radar image forms the surface; everything below it is the method's own output, rendered without smoothing away its structure. Compare a pyramid with open desert and judge for yourself.
Read this before reading the picture. Depth here is not measured. It is the rate at which a pixel's image-registration vector oscillates as the satellite's look angle sweeps through the acquisition, relabelled as a distance through a declared sound wavelength that no measurement in the method constrains. Because the steering wavenumbers are evenly spaced, the volume is exactly periodic: below the marked plane every feature is a copy of one above it. Switch between a pyramid and open plateau and the volumes look alike, which is the finding. The viewer is deliberately generic, so a new site is a new data bundle rather than new code; surveyed chambers will be added as a comparison layer once their placement in the radar image is settled to better than a chamber's width.
