METHOD OF DETERMINATION OF COMPLEX DIELECTRIC PERMITTIVITY OF MEDIUM Russian patent published in 1995 - IPC

FIELD: radio engineering. SUBSTANCE: method of determination of complex dielectric permittivity of medium consists in positioning of transmitting and receiving aerials in investigated medium in horizontal plane, in preliminary orientation of transmitting aerial at angle of 45 deg to line connecting centers of transmitting and receiving aerials, in successive three-stage orientation of receiving aerial at angle of 90 deg along line connecting centers of transmitting and receiving aerials at angle of 45 deg, in irradiation of investigated medium with transmitting aerial and in measurement of levels of received signals at three orientations of receiving aerial, in determination of desired parameters by formulas containing values of measured amplitudes of received signals. EFFECT: expanded application field. 3 dwg
