It has been found that, with plastic deformation in ice, anomalies of its microwave characteristics occurs. It has been previously demonstrated that at plastic flow localized plastic flow autowaves are formed in them. Characteristic flow wavelengths were in the range of 0.5–2 cm. In this work, to account for the anomaly of the microwave characteristics of ice, we searched for localized plastic flow autowaves in it. We measured radio brightness temperature of the ice cover at frequencies from 10 to 34 GHz during significant daily fluctuations of the air temperature. As the direction of the temperature gradient in the ice cover depth changed fast, resulting in plastic deformation, we observed decrease of the radio brightness temperature by 10–15 K. The data obtained confirm the existence of localized plastic flow autowaves in polycrystalline fresh-water ice.
Keywords: microwave range, plastic deformation, nonlinear properties, radiothermal radiation
