title: SENSITIVITY OF ACTIVE PHASED ANTENNA ARRAY ELEMENT OF GURT RADIO TELESCOPE
abstract: PACS number: 84.40.Ba Purpose: theoretical and experimental investigations of sensitivity by the signal-to-noise ratio criterion active antenna used as a phased array element of the GURT radio telescope of new generation. Design/methodology/approach: A mathematical model of active antenna is proposed, the technique of its application for calculation of the active phased array element sensitivity being described. Findings: Numerical and experimental studies of the temperatures of external and int
