摘要：
The technique of operative measurements of wind-induced wave characteristics based on video imaging of the sea surface and simultaneously measuring the current spectra of wind waves using an anchored buoy is presented. This technique makes it possible to obtain the data on frequency-angular and dispersion characteristics of surface roughness required for acoustic measurements. The results of processing the video data obtained from the Baltic Sea and the Gorky Reservoir are in agreement with corresponding theoretical dependences.
