FIELD: radiolocation. ^ SUBSTANCE: method is based physically on different penetrability level of snow by electromagnetic waves of different frequencies ranges, which is connected to dielectric snow characteristics. Method for measuring thickness of snow covering includes irradiation of snow cover at the same time by electromagnetic waves of centimeter range on bearing frequency f1, on which reflection occurs from limit between snow and soil, and electromagnetic waves of optical range on bearing frequency f2, on which reflection occurs from limit of separation of environments troposphere-snow, and determining of appearing difference of distances, passed by proving signals. ^ EFFECT: higher efficiency. ^ 1 dwg |
