The problem for radar contrast of wind waves in the short gravity and gravity-capillary ranges on the sea surface perturbed by a seismic origin wave is solved. Relations of the radar contrast for the sensing wavelengths 3.2 cm and 5.66 cm are investigated versus the parameters of seismic wave and sea depth. The possibility for reliable radar detection of the sea seismic wave with very small amplitude in initial stage of its development is shown. Using «Sich-1» radar satellite data the parameters of seismic sea waves in the area of weak earthquakes near the Turkish Black Sea coast is evaluated.
Keywords: radar contrast, seismic origin wave, sensing wavelength, wind ripples, weak earthquake
