摘要

PROBLEM TO BE SOLVED: To provide a dielectric constant calculation device that calculates a dielectric constant in a radio wave propagation space.;SOLUTION: A dielectric constant calculation device includes: a transmission unit which transmits a transmission wave by an FMCW radar system to a propagation space in a circular waveguide installed to face a body to be measured while sweeping a predetermined frequency at sweeping time; a reception unit which receives a reflected wave, of the transmission wave propagating in the propagation space, reflected by the body to be measured; an extraction unit which extracts a beat frequency as a difference between a transmission frequency of the transmission wave and a reception frequency of the reflected wave when the reception unit receives the reflected wave; and a calculation unit which calculates a dielectric constant in the propagation space of the transmission wave on the basis of the beat frequencies. The transmission unit transmits a transmission wave under different transmission conditions, the extraction unit extracts a beat frequency on the basis of a transmission frequency and a reception frequency of each different condition, and the calculation unit calculates the dielectric constant on the basis of beat frequencies extracted by the different transmission conditions.;COPYRIGHT: (C)2014,JPO&INPIT
