Iemelianenkov B. The Elements of a Millimeter-Wave Sum-Difference Comparator on Dielectric Waveguides

Object of research: millimeter-wave sum-difference comparator (SDC) with taking in account variation of the parameters of the nominal values, development and experimental testing methods for optimizing SDC nodes . Research objective: solving the problem of increasing performance and develop the principles and techniques of optimal design of elements and nodes of millimeter-wave sum-difference comparator (SDC) with taking in account variation of the parameters of the nominal values, development and experimental testing methods for optimizing SDC nodes, namely: phase shifters (PS), directional couplers (DC) on dielectric waveguides (DW), transitions on DW in millimeter wavelength range (MWR), conditions of use of these SDC elements for the SDC with high identity partial channels. Theoretical and practical results and novelty: improved procedures for sensitivity analysis to deviations of SDC elements parameters, it is proposed to model the image guide (IG) horn transition in a 3-mm wavelengths use CST MWS code, a detailed analysis of the pilot study and simulation of horn transitions and installed new regularities in the dependence of their characteristics, developed a general procedure for transitions optimizing, which experimentally confirmed, 3-mm wavelength range IG phase shifter is created, the method of optimization millimeter wave IG DC and a general procedure for registration of parameter deviations IG DC from the nominal values are developed and effect of an equivalent increase in the parameters area connection but which leads to a shift of the uniform division of the signal down in frequency is observed, experimentally confirmed the correctness of the principles of system integration to create a MWR detectors and proven benefits of dielectric waveguides to create a high MWR SDC with identical partial channels. The degree of implementation: the State Research Center "Iceberg" in the development of multi-channel radiometric scanner MMDH and JSC "Radio and Television".
