Abstract

Integration of plurality of radiometers into a panoramic receiving systems seems efficient for realization of `radiovision' (imaging) systems without scanning if small- sized sensors with good operating parameters are available. The use of Josephson Junctions (JJ) in self-pumping mode as one of various heterodyne detection methods is of principally new particular interest and trend, when we consider the properties such as the sensitivity, possibilities of frequency electronic tuning in big band, integrations with HEMT's and other nontraditional technical decisions, including the measuring of frequency of active signals on JJ. According to experimental and theoretical results it is possible to get the sensitivity not less than 0,01 K in 3 mm wave band at cooling temperature 20 - 30 K in passive imaging system at the base of matrix of JJ + HEMT's `pixels'.
