Annotation The research of the microwave properties of salty ice containing NaCl, Na2CO3 and natural ice from the ice lake Doroninskoye at temperatures ranging from −20◦ C to −190◦ C was carried out. We used the following techniques: dielectric measurement of ice samples placed in a waveguide at a frequency of 15 GHz, as well as measuring the radio thermal radiation of ice against a cloudless sky at 5 GHz, 13.5 GHz and 37.5 GHz. Dependences of the real ε′ and ε′′ imaginary parts of the relative permittivity of the samples of salted ice for the temperatures below −60◦ C were found for the first time. The temperature of freezing liquid in the pores of the salty ice was experimentally determined as −145◦ C.
Key words microwave spectroscopy, salty ice.
