T1 SUPPRESSING THE EFFECTS OF INTERFERING FACTORS IN LOCAL MICROWAVE DIAGNOSTICS JF Telecommunications and Radio Engineering JO TRE YR 2016 FD 2016-11-07 VO 75 IS 13 SP 1221 OP 1229 K1 sensor K1 measuring converters K1 permittivity K1 permeability measuring probe AB New principles for the development of measuring procedures in the local microwave diagnostics on the base of aperture resonator measuring converters (ARMC) are justified. A main problem to be solved is to avoid the interfering factors, which exert influence on the measuring results, such as nonreproducibility of the gap between the object and the ARMC aperture plane, aperture geometry, surface shape and object density, nonreproducibility of microwave oscillator and detector parameters etc. This problem can be solved by forming special combined signals based on the usually applied fundamental primary signals, e.g. ARMC resonance frequency and Q change under the object action. In turn, it is proposed to extract these signals via the AFC microwave oscillator by the ARMC resonance frequency. The dependences of fundamental and combined signals on some typical interfering factors are given and the regions with the proposed combined signals invariant to them are denoted. The functional diagram of a universal technical tool for the proposed principle realization is presented.
