The paper presents the first results on the development of an automated high-resolution remote radar system called Ecoradar developed for monitoring water areas for the purpose of automatic detection of film pollution on a wavy water surface. The complex is based on digital coherent panoramic radar manufactured by Micran, operating in the X band on horizontal polarization. An algorithm for automatic detection of film pollution on radar images of a wavy water surface has been developed. The algorithm is based on neuron-like networks, and most of the algorithm is implemented using Nvidia CUDA technology, which minimizes the operating time. To test the algorithm, we used data from previously conducted field experiments to study the kinematics of film pollution based on radar observations in the water area of the Gorky reservoir and the coastal zone of the Black Sea. The paper presents the limitations and recommendations for the use of Ecoradar for the detection of film pollution. The detection range of film pollution at a radar installation height of 12 m above water level and favorable wind-wave conditions reaches 1000 m. The minimum area of confidently detectable contamination is estimated at 500 m2.
