Description

Based on the analysis specification for radio telescopes worldwide VLBI2010-network and experience in the development of the cryogenic receiving focal unit (CRFU) for VLBI-next generation network "Quasar-M" telescopes, the necessary characteristics of cooled to cryogenic temperatures S/X/Ka feeder improved performance for VLBI2010-compatible reflector antenna of the German company "Vertex Antennentechnic GmbH" are identified. Based on the performed experimental research on the causes degradation patterns S/X/Ka feeder offered a new technical solution of CRFU aperture assembly in which the identified deficiencies will be corrected. A number of algorithms, providing analysis of the characteristics of feed, in waveguides which have a dielectric insert was developed. Algorithms introduced in the electrodynamic modeling MWDII, previously developed in IRE NASU, with the participation of the authors of the project. The developed algorithms allow in the second phase of the project to carry out the synthesis and optimization of the complete configuration of the irradiator using modern optimization algorithms.
