Object of research is waves on sea surface and their statistics, optics and radar characteristics. The aim of project is a field experiment on Oceanographic platform of Marine Hydrophysical Institute in Katsiveli and processing and analysis of data obtained by radar, laser locator, video camera and wave staff array. Processing and analysis of data obtained with Ka-band radar, video camera and laser locator were performed. Sea surface slope distribution for different wind velocity was studied. Differences of distribution from Gaussian one were detected. Quantitative characteristics of slope asymmetry were obtained. Radar data base was completed with near-nadir measurements. Impacts of wave breaking to Doppler spectra were isolated. It was shown, that wave breaking affects backscattered signal due to mirror reflection. Radar signal dependences on viewing angle and azimuth were studied. Quantitative characteristics of these effects were estimated, and their physical interpretation was proposed.
