Kim N. Increase of accuracy the measurement of temperature in information-measuring systems monitoring the water environments

Object of research is temperature fields of water environments. The purpose of dissertetion is increasing of accuracy of temperature measurements and speed of IMS monitoring of water environments in view of dynamics of its changes with use of the system approach, by indemnification of errors base gradientometrical method of temperature measurements, correction of a multiplicate making error of temperature gradients measurements, establishment efficiency of the developed methods and means by using offered techniques based on a quantitative estimation of degree of reduction errors. In work being used methods and algorithms of digital signals processing, methods of imitating modeling, theory of measurements and errors, theory of probability and mathematical statistics. The equipment of research is gradientometrical measuring channel of temperature in structure IMS. The theoretical results consist in development of mathematical bases, algorithms of their realization and new methods of increas ing accuracy of measurements of gradients and temperature of water environments. The practical results are basing on the results of imitating modeling and created technique of estimation efficiency of the developed methods and hardware-software means. The novelty of used consists in development of advanced gradientometrical method of temperature measurements; development of hardware-software means, which compensating additive and multiplicate making errors of temperature measurements; in creation technique of an estimation efficiency of the developed methods and hardware-software means. Degree of use. The advanced measuring channel of temperature in structure of information-measuring system, according to developed in dissertation principles, methods and means of increasing accuracy, being used in the detached structural division «Department № 2» SKTP «Turbulentnost» at Donetsk state university. Area of use is hydrophysical, oceanological, ecological researches of water environments in the field of ecology.
