Розвиток теоретичних основ побудови радіовимірювальних приладів з комутаційно-модуляційним перетворенням

Abstract

Dissertation is devoted to increase the sensitivity and accuracy, expanding bandwidth and functionality of radio devices. Use new methods and means of transformation, separation and measurement of informative parameters of low-intensity signals against the intrinsic noise of the transducer elements paths instrumentation using switching and modulation changes. We analyzed the system changes the properties of the objects in the radio measurements. Received model and investigated the electrical connection settings substances with their physical and chemical properties. Principal possibility of use of radio devices for measuring substances. We studied the principles of structural construction of radio devices with a variety of sensors. Proposed new structure of radio equipment the opportunity of enhancing their accuracy and sensitivity. The characteristics of microwave radiometers that have a decisive influence on the measurement accuracy. With the use of the proposed new technical solutions created radio devices, will measure parameters of materials natural and artificial origin. Developed technical solutions protected by patents of Ukraine, introduced in operation and are used in the Head Office of metrological ensure electrical and electronic measurements of Ministry of Health of Ukraine - NDC quantum medicine "Vіdguk" (Kiev), state scientific research enterprise "Kvarsit" (Konstantinovka), Kiev National University of Technology and Design, the National Technical University of Ukraine "KPI".
