PROJECT TITLE :
Contactless Detection of State Parameter Fluctuations of Gaseous Media Based on an mm-Wave FMCW Radar
In this contribution, we gift an approach on the fluctuation detection of gaseous media regarding their state parameter, i.e., concentration, pressure, and temperature. Dielectric mixing equations that link the gas permittivity with the gas concentration and pressure are introduced and discussed. Furthermore, we have a tendency to prove the little temperature influence on the gas permittivity, as a result of of the obvious temperature–pressure dependence of gaseous media. To verify the instructed gas permittivity theory, a pressure-resistant test container was constructed and built up. By means that of a highly precise millimeter-wave radar system, we performed various test series on completely different gases for various investigations.
