  • Method for determining hydrographic parameters which describe a sea swell field in situ using a radar device
    Patent number: 6775617
    Abstract: In a method of determining hydrographic parameters describing a sea swell field from analog signal sequences supplied by radar devices, wherein a sequence of digitized signal in spatial coordinates is generated from the analog signal sequences and, by Fourier transformation, a three-dimensional complex value frequency wave number spectrum is determined therefrom, which is filtered on the basis of the dispersion relation principle that inter-links the wave numbers and the frequencies of the sea swell for a localization of the sea swell-specific parameters by separating the signals from the noise and determining the signal to noise ratio and from the ratio the height of the waves and, by localizing the signal coordinates in the surface area defined by the dispersion relationship, parameters describing the surface currents of the sea swell field in a three-dimensional spectral space and the water depth, from the phase information concerning the waves monitored in the sea swell field the parameters of the sea swe
