The current stage in the development of experimental radiophysical and optical methods for studying the environment is characterized by the transition from passive collection of information on the object under study to the formulation of purposeful experiments. Of paramount importance in the implementation of such experiments are the organizations of mass gathering of information about the system under study, the speed of its processing and the reliable interpretation of the observational data. Of particular relevance in recent years have acquired remote technologies that allow obtaining operational information about water bodies and characterized by high productivity. The procedure for the synthesis of an automated data processing system for multichannel measurements includes the creation of a complex of hardware, algorithmic, model and software tools for collecting and analyzing information, taking into account the levels of its reliability and completeness. In this paper briefly describes the physical foundations of water and ice characteristics according to microwave data. A review of the work is presented where, based on model calculations and experimental measurements, the emissivity of the ice cover in the microwave range is described, the questions of the development of models for sea ice with strong and moderate absorption and porous structures, the features of the radiation indices of young ice, ice with low salinity and pack ice. Specific examples of the classification of phenomena on the water surface and ice cover are given. The program modules included in the system were used to process data from radiophysical experiments with the Kosmos-1500 satellite for the Arctic regions. The statistical characteristics of the "spottennes" of the radio brightness temperatures, obtained for the most informative thresholds, are analyzed. It is asserted that these characteristics can be used in the detection of abnormal phenomena on the water surface and ice cover.
