A Mobile Full-Revolving Radiometric Complex for Astronomical and Atmospheric Research.

A radiometric complex for astronomical and atmospheric research in the 3-mm wavelength range has been developed. The radiometer is assembled according to the modulation scheme with a mechanical obturator based on oversized quasi-optical waveguides. A Cassegrain antenna with 1° far-field pattern at a −3 dB level is used as the antenna system. Calibration is carried out using a built-in noise generator. The receiving system of the radiometer, together with the antenna, is placed on a two-coordinate turntable for observations in a selected region of the celestial sphere. Control, as well as capture and processing of experimental data, are performed remotely using the developed software. [ABSTRACT FROM AUTHOR]
