Abstract

The paper presents a technique to observe experiment ally backscatter o SHF rrom the sea . Analysis o spatial stru cture o microwave sea echo shows that spectral characteristics or the radar reflected pulse (wavelengths 3 ,1 0 cm ) are determined in general by angle or incidence and the azimuthal divergence or the illuminated area. A non—linear errect is considered to attempt to explain rine structure in the spectrum or the backscat tered signal. Temporal characteristics or radar backscattering were s tudied by Doppler measurements (wavelength 1 .5 cm ) . We inves tigated. a deviation or radar signal statistical distribution rrom the Raleigh one and how this deviation connects with sea surrace state. Variations or Doppler spectrum gives us the possi bility to obtain some inrormation about capillary- gravitational waves which are modulated by large-scale waves.
