Интенсивность отраженных от морской поверхности сигналов зависит от большого количества различных факторов, определяемых как конструкцией радиотехнического средства, так и состоянием моря. Основным параметром, определяющим интенсивность отражения, является удельная эффективная поверхность рассеяния морской поверхности. В статье рассмотрены различные модели удельной эффективной поверхности рассеяния для малых углов скольжения, при различных условиях наблюдения, показаны границы их применимости. Произведен анализ точности относительно экспериментальных данных. На основе расчетов автор представил достаточно прозрачную методику оценки соответствия результатов использования моделей полученным эмпирическим данным.

The intensity of the signals reflected from the sea surface depends on the sea state, collection geometry, wind speed, direction, and radar frequency. The main parameter determining the intensity of reflection is the sea normalized radar reflectivity. The article discusses various models mean backscatter models at low grazing angles, under different observation conditions, and shows the limits of their applicability. The accuracy of the experimental data is analyzed. Based on the calculations, the author presented a fairly transparent methodology for assessing the compliance of the results of using models with the empirical data obtained.
