The antenna is set in a superstructure of the surface ship (SS) and is intended for a long-distance radio communication in the range of 10-30 MHz. The antenna power is four single-turn windings with ports on multilayered ferrite cores of a loop. Effect of the phase feeding of the ports on the directional properties and efficiency of the antenna was studied taking into account the electromagnetic interaction with the SS body and the underlying surface. The radiation patterns in the main planes and the values of the efficiency of the MA-SS system at frequencies of 10-30 MHz for different modes of antenna power are presented.","PeriodicalId":158616,"journal":{"name":"2019 Radiation and Scattering of Electromagnetic Waves (RSEMW)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125296413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mathematical analysis and simulation of the method in the autocollimation mode of the RATAN-600 radio telescope were performed and initial experimental results are presented. Using this proposed method on a radio telescope does not require special receiving equipment and a standard radio astronomy receiver can be used for holography measurements with a coherent remote ground or space signal source. The influence of the surface layer atmospheric turbulence on the process of consecutive recording of three holograms will limit the usability of the method for large ground radio telescopes. However, due to its simplicity, the method can be successfully applied to holographic measurement of smaller precision ground reflector antennas (up to 50 m) or any precision space radio telescope with an active surface.","PeriodicalId":158616,"journal":{"name":"2019 Radiation and Scattering of Electromagnetic Waves (RSEMW)","volume":"231 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115906801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TE and TM fields in the waveguide are described by the longitudinal components of magnetic and electric vectors, respectively. The wave equations for the specified components are received from Maxwell equations, which are reduced to the Mathieu-Hill equations by changing variables. The solutions of these equations in the frequency domain of \"weak\" interaction of signal wave with modulation wave (the Wulff-Bragg condition is not satisfied) was found with an accuracy of terms proportional to in the first degree of modulation indexes. It is shown, that TE and TM fields in the waveguide in the approximation, indicated above, consist of the sum of three space-time harmonics with different amplitudes.
