Methodology for determining the quality of functioning of the digital processing system of remote sensing data of the Earth

The article is devoted to the issue of a priori determination of the values of the main characteristics of the Earth remote sensing data processing system in the radar range to ensure the quality of its functioning, while the assessment is performed according to one key parameter - the processing time of the incoming data. It is influenced by several parameters of the system, which are called private attributes of quality. An aggregated mathematical model of a digital processing system, particular attributes of the quality of its functioning, and their relationship with a key parameter are considered. The methodology for assessing the quality of the functioning of the digital processing system is shown, with the use of which the required and permissible values of its technical characteristics are determined. This space practically defines the limitations for the analysis of existing and design of promising systems of this kind. From a practical point of view, the presented material is useful both for the customer of the system development and for the project executor, since it can be used to present requirements for a new system and to analyze the possibility of the old system functioning in new conditions, in addition to analyzing the project. The article can be recommended for reading to specialists in the field of circuitry in relation to the development of systems for processing radar signals.
