FIELD: electricity.
SUBSTANCE: in the proposed method, the specified controlled area of the sea surface is irradiated with microwave radio waves of a given vertical polarization frequency, the backscattered signal is recorded at the same polarization (vertical), the polarization of the radiator and receiver is made orthogonal and the same portion of the sea surface is probed at the same frequency, the backscattered signal is registered, after which, according to two successive soundings, the polarization ratio is calculated, according to which the salinity is calculated.
EFFECT: increased accuracy of measuring the salinity of sea water by eliminating the effect of variability in the sea surface roughness on the result of measurements.
