Abstract: We give a review of fundamental works on the representation of the relief of sea waves on photographic and radar images. We developed some special-purpose instruments for image treatment with the use of optical Fourier transformation, namely, an immersion cell combined with a fourier-lens and an optical analyser with vacillating light guide for decrease of speckle. A scanner for detection of spatial spectra in polar coordinate system is developed and constructed. Digital methods for calculation and correction of parameters of sea waves are applied. Some results of expeditions for the sea surface aerosurvey of the Black Sea and Barents Sea are processed. A space image of the Sea of Okhotsk is analysed.
