Scientists of the Remote Sensing Laboratory of the Moscow State Technical University named after N.E. Bauman developed a non-destructive method for carrying out archaeological work. The study appeared in the journal Insight – Non-Destructive Testing and Condition Monitoring.

The archaeological radar technique will confirm the discovery of unknown cavities in the Great Pyramid of Giza (Pyramid of Cheops), made using ScanPyramid muon detectors. The new method will provide accurate determination of the location and shape of the cavities.

The Cheops pyramid consists of blocks of limestone and granite, which are classified as dielectric materials. They, like many soils, are translucent to electromagnetic waves in the radio and microwave ranges. Such materials can be investigated using subsurface radar techniques.

The main parameters for research calculations using the new technique are frequency, real part of the dielectric constant, attenuation coefficient, layer thickness, dimensions of voids along the transverse axes and along the longitudinal axis.

Scientists believe that with the help of this data they will be able to determine the position of the voids and approximately estimate their size even in the field. Digital reconstruction of the recorded radar holograms will provide accurate information about inhomogeneities or voids inside the Cheops Pyramid.

Also, the authors of the work propose to use the radar method in the study of other archaeological objects: stone fortress or monastery walls, ancient buildings and structures more than 1.5 m thick, and even the Great Sphinx in Egypt.
