Microwave radiometric systems are a key tool for remote sensing of the atmosphere, providing measurements of temperature, humidity, cloud particle concentration and other parameters. Modern requirements to increase spatial and spectral resolution, as well as to minimize the mass-size characteristics of the equipment stimulate the introduction of radiophotonic technologies. In the article the principles of integration of radiophotonic devices into multifrequency radiometric systems, their advantages in the context of broadband signal processing, generation of stable reference frequencies and beamforming are considered. The prospects of application of such systems for monitoring of atmospheric processes, including forecasting of extreme weather events, are analyzed. - Estimation of fluctuation sensitivity of millimeter-wave radiophoton radiometers

The report presents a set of methodological recommendations for realization of the method of digital increase of accuracy of forecasts of dangerous atmospheric phenomena at adaptive change of sensitivity of multiband microwave measurements, at investigations of structurally heterogeneous precipitation areas on the basis of solution of the problem of optimal choice of the time of accumulation of the output signal. Estimation of the limit values of the output signal accumulation time in each frequency range, based on the condition of excluding the omission of relative changes in the output signal, caused by the appearance of structural inhomogeneity in the effectively radiating longitudinal region of the atmosphere, for example, in the form of a zone of intense precipitation. - Prospects of using the optical measurement channel as a part of the complex system of remote sensing of the atmosphere

The article considers the prospects of introducing an optical measurement channel into the composition of a complex radiophysical system of remote sensing of the atmosphere. Lidar systems of atmospheric monitoring for distribution of aerosol and chemical composition of air, as well as wind speed and direction are the most widespread. The study of aerosol and gas composition of air is especially important in the tasks of environmental monitoring of areas associated with hazardous industries and global transport of pollutants, including greenhouse gases. Molecular (gas) atmosphere at laser sounding is manifested in absorption, in the phenomena of molecular (Rayleigh), Raman, resonance scattering and fluorescence. These phenomena differ in their intensity or interaction cross sections and, consequently, in the possibilities for reliable registration of signals. Atmospheric parameters such as wind speed and direction, visibility, density and height of cloud layers change both temporally and spatially, which can lead to the formation of dangerous meteorological phenomena. Atmospheric aerosol plays an important role in climate change, so monitoring its composition and dynamics is essential for assessing climate change on a global scale. - Radiophotonic path of intermediate frequency signals of multifrequency microwave radiometric system for remote sensing of the atmosphere

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. - Calibration of a three-band microwave radiometric system by an external noise signal source

The article considers a method of solving the problem of calibration of a tri-band microwave radiometric system by an external source of noise signal. The peculiarity of the given method of calibration is the location of the calibrated noise signal source in the base of the common antenna mirror with reception to the common aperture of the system’s illuminator. The questions of technical realization of a noise source as a broadband noise generator taking into account frequency dependence of output noise power value supplemented by an attenuator for obtaining a two-level calibration signal are considered. In article the theoretical positions underlying the given way of calibration in values of measured radio-luminous temperature are resulted, and time dependences of measurements of radio-luminous temperature of atmosphere are shown at an antenna direction in a zenith with inclusion of an external source of a noise signal at performance of calibration of microwave radiometric system. - Short-term forecasting of atmospheric meteorological parameters based on the results of the neural network of a three-band microwave radiometric system

This work relates to the problem of forecasting dangerous weather events - heavy rains and heavy precipitation in the form of snow and hail in a certain area based on the results of passive microwave radiometric measurements. The article presents the results of research on the possibility of implementing a multi-band method for detecting and monitoring rain zones with inclined microwave radiometric sensing at small angles. The analysis of the influence of a remote rain area on the atmosphere radio brightness temperature during horizontal sounding of a multi-frequency microwave radiometric system is performed. Numerical estimates of the radio brightness temperature and its increase due to the presence of the rain zone in the direction of sounding are obtained. The atmosphere with rain thermal radiation power measurements data, made by a tri-band microwave radiometric system, show a trend for different time of the system output growth formation, when the rain area approaches to the place-based microwave radiometric system. - Use of the Sun's radiothermal radiation as an external source for research of multi-frequency microwave radiometric system antenna parameters with background noise compensation
