On a Problem of Marine Current Velocity Estimation from Microwave Radar Data

The paper is devoted to the problem of estimating marine current velocity from microwave radar data, one important tasks sea remote sensing. We present some results simultaneous measurements scatterers velocities and wind velocities. Radar were measured using a dual-polarized (VV/HH) Doppler operating in S/C/X bands. experiments carried out coastal zone Black Sea at moderate incidence angles (30–70 degrees). It was obtained that subsurface (current upper layer ten centimeters) retrieved Bragg component return can be used estimate changes (a part not related wind) constant speed. found as vector sum depth 1 m equal 1–3% Possibilities VV/HH/PD data are analyzed.
