METHOD OF VARIABLE SEA CURRENT IDENTIFICATION ACCORDING TO RADAR OBSERVATIONS DATA Russian patent published in 2017 - IPC G01S13/88 

FIELD: measuring equipment.

SUBSTANCE: method is based on the observational analysis by the multi-frequency dualpolarized super-high-frequency radar, which sends out and receives the scattered by the surface radio signal on two coaxial polarizations (same-sense polarizations) - HH (signal sending and reception on the horizontal polarization) and VV (signal sending and reception on the vertical polarization) - and on several operation frequencies within the range from 1 GHz to 20 GHz spread out in size no fewer than twice. The method is applicable within the conditions of the medium winds at the observation angle of 20-80° from the vertical line from the piled foundations or crafts.

EFFECT: identification of the time and over a distance varying sea currents that are usually connected to the progressive internal waves by scales of around hundreds of metres - units of kilometres.
