Modernization of the pattern control system for the north-south antenna of the DKR-1000 FIAN radio telescope
Abstract
The paper describes the electrical scanning system based on circulators that has replaced the mechanical scanning system of the north-south antenna of the DKR-1000 FIAN radio telescope. Beam pointing accuracy is examined, and changes of effective antenna area in the scanning mode of operation are investigated taking into account mutual coupling. Calibration measurements indicate the probability of high accuracy and reliability of radio-astronomical observations.
