Abstract

Until recently a one-band radiometer was exploited at the radio-telescope RT-7.5 for Sun observations. To receive more information about processes in the Sun in the course of the long-time program of Sun observations a two-band receiver was designed. By means of this receiver an intensity of radiation at the wavelengths 2.2 and 3.2 mm can be measured in every direction simultaneously that allows one to determine a spectral index. The receiver is assembled and installed at the antenna. Experimental operation of the receiver began. In accordance with the results some units of the receiver are being improved
