Technique for estimating the volume of storage and transmission of information from satellite synthetic-aperture radar (SAR) in data centers (DCs) in the digital economy problems is proposed. This technique takes into account the full statistical harmonization of the analog messages generation source with digital storage, processing and transmission systems. The proposed technique is detailed on the example of the statistical model of the process of generating analog SAR information in digital control systems for effective land-use management. The practical importance of this technique involves the possibility of statistical estimation of the storage and transmission of information from satellite SAR in the data centers, while allowing modeling and constructing specific data bases that are optimal in terms of the information volume. © 2020, Univelt Inc.
