Fine Structure of Centimeter Electromagnetic Waves Backscattered from a Sea Surface

摘要

Analysis is presented of the experimental data obtained in the Doppler measurements of wind-induced waves, performed from the deck of a ship. The phase measurements coupled with a detailed digitization of the signal allow one to extract the resonant Bragg structure of the Doppler spectrum and to obtain a number of space-time characteristics of sea waves in a wide range of wavelengths. A possibility is shown of restoring a one-dimensional shape of the sea surface and estimating irregularities of short-wave components of sea waves.
