  A problem with synthetic aperture radar (SAR) is that, due to the poor
penetrating action of electromagnetic waves inside solid bodies, the capability
to observe inside distributed targets is precluded. Under these conditions,
imaging action is provided only on the surface of distributed targets. The
present work describes an imaging method based on the analysis of
micro-movements on the Khnum-Khufu Pyramid, which are usually generated by
background seismic waves. The results obtained prove to be very promising, as
high-resolution full 3D tomographic imaging of the pyramid's interior and
subsurface was achieved. Khnum-Khufu becomes transparent like a crystal when
observed in the micro-movement domain. Based on this novelty, we have
completely reconstructed internal objects, observing and measuring structures
that have never been discovered before. The experimental results are estimated
by processing series of SAR images from the second-generation Italian
COSMO-SkyMed satellite system, demonstrating the effectiveness of the proposed
method.
