Results of research in the field of remote sensing methods for detecting oil pollution on the water surface conducted at the RSHU

Abstract

The article presents the scientific results which are a generalization of almost twenty years of experience of the staff of the department of information technology and security systems of the Russian State Hydrometeorological University in the field of remote sensing methods of oil pollution on the water surface. The choice of radar systems for the implementation of remote monitoring of the water surface on the characteristics of efficiency and coverage of the area of responsibility is substantiated. Structurally, the radar monitoring system should consist of a network of centimeter and millimeter range radar systems. The use of centimeter-range radar systems is due to the preservation of their operability during intense precipitation. Millimeter-wave radar systems are characterized by higher radar contrast, which significantly increases the effectiveness of environmental monitoring of water areas, their performance depending on the weather conditions. Thus, a combination of radars of two ranges allows continuous monitoring of the water area in any weather conditions. Radar systems are a recording module as part of an object monitoring system. The facility monitoring system, in addition to existing systems at the regional level, allows to receive information on the environmental situation promptly. This is especially true in case of emergency situations that occur during loading and transportation of oil products and other environmentally hazardous substances. The most significant result of many years of research is the concept of an automated distributed system for remote environmental monitoring of the water surface. For each module of the system, methods and models for processing spatial data and algorithms for the distribution of measuring instruments in the monitoring space are proposed. The purpose of the functioning of such a system is associated with detecting oil spills on the water surface, monitoring the dynamics of pollution and predicting the development of emergencies resulting from environmental disasters. International cooperation in the field of environmental protection is shown to be international in nature, the joint projects being an effective tool for development of scientific and educational potential of higher education in the field of ecology. Participation in international projects not only allows to increase the scientific and educational potential of higher education, but also influences the formation of environmental policy
