MOSCOW, July 3NCFU scientists have created a unique system for remote analysis of the state of soil and sea ice. According to the authors, the development will become a key sensor for smart farming systems, and will also help optimize the costs of creating transport sea corridors in the Arctic. A patent has been received for the development, the press service of the university reported.
Systems for remote sensing of the earth's surface, according to scientists, today are increasingly based on UAVs, and not on satellites. This approach allows to achieve much more detailed data and increase the speed of data collection and processing.
A number of types of the earth's surface — such as the soil cover of farmlands or the ice cover of the oceans — belong to the so-called flat-layered dielectrics. According to scientists, knowing the dielectric constant and specific conductivity of these media, it is possible to determine soil moisture and salinity, thickness, density and salinity of sea ice, as well as a number of other physical and chemical parameters.
Researchers at the North Caucasian Federal University (NCFU) have developed a new method for remote measurement of the dielectric constant of the earth's surface, surpassing analogues in accuracy, efficiency and economy. increase the productivity of the agricultural industry by 20%, — ensuring the flow of accurate and timely information on the physical and chemical parameters of the soil. Our development can automatically collect all the necessary data of this type,” said Gennady Linets, head of the NCFU Department of Infocommunications.

The key feature of the development, as the creators explained, is the use of two unmanned aerial vehicles at once, forming a radar probing system. Tests have shown that the probability of measurement error in the new system is about 1%.
Another practical application of the new system is the selection of the optimal course for icebreakers by measuring the thickness and density of sea ice. According to scientists, this will significantly optimize the cost of escorting ships along the Northern Sea Route. /ria.ru/20230417/nauka-1865017407.html» data->
«The existing analogues of our methodology are either laboratory studies that require too much time to remain applicable, or aerospace sounding, which has insufficiently high accuracy and requires expensive infrastructure,” said Linets.
A patent No. 2790085 has been received for the development. In the future, the research team intends to finalize the software and hardware complex to control the proposed development and create a full-fledged geoinformation system for smart farming on its basis.
