Information × Registration Number 0212U000986, 0109U009071 , R & D reports Title Theoretical and experimental research of noise immunity of receiving antennas of the ground and space radiocommunication systems popup.stage_title Head Lobkova Ljubov Mihajlovna, Registration Date 24-07-2012 Organization Sevastopol National Technical University popup.description2 The object of research - ground and satellite communication channels and spiral antennas. The purpose - development of statistical model of the receiving antenna field taking into account the space-frequency fluctuations of amplitude and phase of an electromagnetic wave on direct (earth) and inclined (satellite) paths of waves propagation, and also development of band receiving antennas. Research methods - theoretical research of statistical model of communication channel, theoretical and an experimental research of characteristics of spiral radiators and their arrays. The review of phased antenna arrays and their primary irradiators, volume and plane, is carried out. The mathematical models, describing polarizable structure of a radiation field of the four-way cylindrical, conical and hemispherical spiral antennas are presented. The analysis of statistical characteristics of the radiation field within receiving aperture taking into account influence of turbulent atmosphere is carried out. It is executed theoretical and an experimental research of conical spiral irradiators and their two-element array. The method of creation of correlation arrays is offered and implemented.
