METHOD OF MICRORELIEF CONTROL OF MOISTENED GROUND Russian patent published in 2018 - IPC G01C11/02 

FIELD: excavation.

SUBSTANCE: invention relates to remote sensing means. Method for monitoring the relief of a moistened surface involves surveying the surface in the first and second bands of electromagnetic radiation, one of which is the infrared band, identifying of diagnosed relief features using the survey data of the first and second electromagnetic radiation bands. Panoramic space radiometric survey of a moistened surface is performed in the first, infrared band, and its sections are grouped by the average ground temperature T_{aver, section Z}, °K. At least two series of synchronous surveys of the moistened surface are performed in the first band and in the second band, the microwave band, in sequence for each group of sections, during which the brightness temperature of the ground is determined at certain points of section T^b_i,t1, T^b_i,t2 and in case of more than two series of simultaneous surveys T^b_i,tN, °K, average value of the brightness temperature of ground T^b_av,t1, T^b_av,t2 and in case of more than two series of simultaneous surveys of T^b_av,tN, °K, difference in the microwave radiation intensity at certain points in the section relative to the average temperature ΔT^b_1i = (T^b_i,t1 – T^b_av,t1), ΔT^b_2i = (T^b_i,t2 – T^b_av,t2) and in case of more than two series of simultaneous surveys ΔT^b_Ni = (T^b_i,tN – T^b_av,tN), °K, the average ground temperature of the section measured in the infrared band T_av,t1, T_av,t2 and in case of more than two series of simultaneous surveys of T_av,tN, °K. Based on the results of the measurements made, the contrast of the radiations in the first and second bands is determined Δu_i = (ΔT^b_1i / T_av,t1 + ΔT^b_2i / T_av,t2 + ΔT^b_Ni / T_av,tN) and the relative level of the horizon at individual points of the section Δh_i = k_P ⋅ (e^Δu_i – 1), m, where k_P is the empirical coefficient, depending on the ground density. Isolines of magnitude Δh_i are constructed, characterizing the microrelief of the ground surface and its moisture content.

EFFECT: technical result consists in increasing the accuracy and efficiency of control of the microrelief of the ground surface.
