METHOD OF REMOTE DETERMINATION OF SPATIAL DISTRIBUTION OF THERMAL PHYSICAL PARAMETERS OF EARTH SURFACE Russian patent published in 2018 - IPC G01J5/00 

FIELD: measuring equipment.

SUBSTANCE: measurement of radiation temperature of earth surface under study (2) by means of equipment mounted on an unmanned flying vehicle (1) of helicopter type. The heat and temperature conductivity of the earth surface is calculated (2). The spatial distribution of the obtained parameters is constructed. In this case, reference materials (3) are set on earth surface (2) under study with known values of thermophysical parameters. These materials are subjected (3) to solar radiation from the sunrise to the sunset. Simultaneously with given interval, the total and reflected solar radiation delivered to the earth surface (2) under study is recorded, and radiation balance of earth surface under study is measured (2). Then ambient and soil temperature, wind speed, radiation temperature on the surface of the reference material (3) and the earth surface (2) under study are measured from the sunset up to the sunrise. The averaged energy luminance of the reference materials (3) is determined using the obtained measurement results. The heat and temperature conductivity of the earth surface under study (2) is clarified.

EFFECT: increased accuracy for determining spatial distribution of the thermophysical parameters of the earth surface.
