The statistical properties of the ultrasonic signal scattered at a rough surface of both clean water and water covered with a layer of oil substance in an outdoor pond were cxamined. The resu]ts obtained by means of frcc-floating acoustic buoy-like system confirmcd all the laboratory rcsults and predictions of high-frequency scattering theory. The proposed system cnables the remote, contactless sensing and dctcrmination of the principal physical properties of the oil substance spread on the rough water surface on the basis of scattered signal statistics considerations.
