Abstract

The work is devoted to the experimental study of Doppler velocity in artificial surfactant films on the sea surface. Such films simulate the oil spills. The paper develops a method of remote detection of oil spill pollution on the water surface. The method is based on a joint analysis of amplitude and velocity radar images of the water surface. It is shown that the surfactant films lead to a significant change in the Doppler velocity, which can be used to increase the detection probability of pollution on the sea surface. A statistical analysis of the two-dimensional distribution of RCS and Doppler velocity in artificial surfactants films and pure water in a wide range of weather conditions is performed. It is demonstrated that the difference between the measured Doppler velocity in the upwind direction and the phase velocity of the Bragg waves corresponds with the slick drift velocity.
