Abstract

Phase increments of the coefficient of microwave reflection from the air-ice interface have been measured at a frequency of 13.8 GHz at temperatures in the vicinity of the ice-water phase transition. It is established that the phase of the reflection coefficient exhibits variations within several dozen degrees upon the appearance of the first signs of ice melting. This phenomenon has to be taken into account in interpreting the results of phase-sensitive radar probing for glacial objects. PACS numbers: 41.20.Jb
