METHOD TO DETERMINE DIELECTRIC PERMEABILITY OF DIELECTRIC OBJECT Russian patent published in 2010 - IPC G01N22/00 

FIELD: electricity.

SUBSTANCE: when determining dielectric permeability of dielectric object at the background of reflector, dielectric object is radiated by coherent microwave radiation at N-frequencies to produce three-dimensional microwave image of dielectric object and reflector, and with the help of two or more video cameras synchronised with source of microwave radiation, produced video image is converted into digital form, and three-dimensional video image of specified area is built, changing three-dimensional video image and microwave image into general system of coordinates, distance Z₁ is determined between source of microwave radiation and reflector, free of dielectric object and distance Z₂ between source of microwave radiation and section of microwave image of reflector in zone of dielectric object, and using video image, distance Z₃ is determined in general system of coordinates between source of microwave radiation and video image of dielectric object, afterwards dielectric permeability of object is determined based on ratio:

EFFECT: provides for remote determination of dielectric permeability of moving dielectric object of irregular shape.
