Annotation The article presents the results of laboratory and field studies of the microwave characteristics of ice containing an amorphous fraction. To determine the electromagnetic parameters of ice structures containing such fraction, the results of early studies and special experiments were analyzed. The intensity of the radiothermal radiation of the growing ice cover was measured on the model at wavelength of 0,88 cm at air temperature below -20 ° C. The anomaly of the behavior of radio brightness temperature has been revealed, expressed in a decrease of its average value for the initial stage of ice formation. Earlier, radio brightness anomalies were observed in the airplane experiment at wavelength of 2,3 cm for measurements ice covers the group of lakes, expressed in pulsations of the mean value over a time in the order of ten minutes. The behavior of the dielectric constant of fresh ice as a function of its lifetime and temperature effects are investigated using a resonator and a waveguide at frequencies of 6,5; 34 and 90 GHz. The results of the study showed that freshly formed ice contains a significant amount of amorphous ice, which is transformed into crystalline ice when the samples are held. This conclusion was confirmed by other researchers in recent X-ray studies of ice formed by freezing water in metal cuvettes. The appearance of amorphous ice is associated with its creep (slow plastic deformation in the relaxation of internal mechanical stresses), as well as with rapid plastic deformation of the medium at mechanical stresses exceeding its yield point. In the latter case, the ice acquires the properties of a medium with spatial dispersion and it is possible to exhibit nonlinear electromagnetic effects in the interaction of the electromagnetic wave with waves of plastic deformation. One could explain the previously observed features in the microwave remote sensing data by the process of ice amorphization.
