“…The unidirectional microwave radiometric measurements of the radio-thermal radiation of the atmosphere in three frequency bands with the central frequencies of the bands 7.5 GHz, 10 GHz, 22 GHz were performed using a three-band microwave radiometric system with the reception on a common antenna mirror with a disclosure diameter D = 2400 mm when implementing a serial frequency separation in the mode splitter of the illuminator with formation at frequencies 7.5 and 10 GHz two output signals, conditioned by reception on two linear polarizations -vertical and horizontal, and also an output compensation signal, conditioned by reception on angular area of dispersion of the AP in main measuring channels [11]. The structural diagram of the tri-band microwave radiometric system and the mode separator of the mirror antenna illuminator are shown in figures 1-2.…”

The results of the correlation analysis of the data of measurements of radio-thermal radiation of heterogeneous atmosphere with precipitation by the three-band microwave radiometric system with reception along one direction to the common aperture of the mirror antenna at three frequencies 7.5 GHz, 10 GHz, 22 GHz are presented. Correlation coefficients of output signals of all receiving channels of the system with the results of measurements of meteorological parameters - temperature, intensity of precipitation, humidity of the surface layer of the atmosphere, obtained from the meteorological stations of five cities, nearest to the location of the measuring microwave radiometric complex are calculated. The dependence of measurement results with and without compensation for the influence of external influences at different frequencies on the degree of homogeneity of meteorological parameters of the atmosphere and on the presence of local inhomogeneities in the atmosphere and their remoteness from the location of the measuring microwave radiometric complex is shown.

The theoretical bases of a method of carrying out calibration of microwave radiometric system on a noise signal of the external noise generator are analysed, the parameters setting value of gain of antenna temperature at introduction in structure of system of such external source of a calibration signal are determined. The questions of technical realization of an external source of a calibration signal for microwave radiometric system are considered, the structural scheme is presented, the place of its arrangement in structure of the antenna is determined. The necessity of using a horn antenna to create directional radiation towards the mirror antenna emitter is shown. The data on the design of such a calibration signal source for the case of its use in a three-band microwave radiometric system with the reception of a noise signal at the common antenna aperture and a sequential separation of the input signals of the three bands in the feeder path of the common mirror irradiator are presented. The influence of the design and, accordingly, the directional properties of the horn antenna of a microwave radiometric system calibration signal source on the coefficient characterizing the radiation divergence created by the noise generator horn, as well as the frequency properties of this coefficient are analysed. The results of measurements of radio-thermal radiation by a three-band microwave radiometric system when two calibration periods with reception of a radio-noise signal from an external calibration signal source located at the base of the antenna mirror are presented.
