Abstract

The article considers the principles of construction of radiometric receivers in cm, mm and submillimeter wave bands. The basic characteristics, construction and results of measurement of main parameters of scanning mirror antenna and microwave channels including filters, modulators, multifrequency horn feed antennas that combines submillimeter range with millimeter and centimetric ranges are offered. The results of development of a radiometer with digital processing, results of optimization of sensitivity of this radiometer are given. The results of development of a radiometer with a pilot signal and its experimental performances are circumscribed. The comparative estimation of sensitivity for the different schemes and constructions of radiometers is given.
