METHOD OF AEROGAMMASPETROMETRICY OF GEOLOGICAL PURPOSE

摘要

FIELD: geophysics; geochemistry.;SUBSTANCE: invention relates to the field of geophysics, geochemistry and remote sensing of the Earth. Method of aerogammaspectrometry of geological purposes is characterized by the fact that an unmanned aerial vehicle (UAV) is used as an aircraft, while shooting is performed while driving the UAV on autopilot according to the previously prepared and corresponding constant height of the UAV over the relief (from 3 meters) to the flight task, the speed of the UAV can vary from 0 (for a set of gamma-ray spectrum with a larger exposure) to 20 m/s, while measurements of the radioactive radiation flux are made along the lines U, Th, K⁴⁰, as well as the integrated intensity of gamma radiation (radiometric channel), continuously in automatic mode, while surveying is accompanied by a multispectral photographic survey that provides an estimate of the vegetation biomass for making appropriate corrections to the measurement results, and spatial binding of measurement points is carried out by means of the satellite navigation system.;EFFECT: technical result is an increase in the accuracy, detail, informativeness and reliability of the aerogram spectrometric survey.;6 cl, 1 dwg
