Zusammenfassung |
The Kirchhoff approximation is used to determine the sea
state bias in radar altimetry. A weakly nonlinear model of the sea waves is used to derive
the joint moments of two different points separated by a distance R; the bias moment is
formulated, and found for power law spectra. The method provides a consistent analysis of
the sea state bias and avoids the need to truncate the high frequency tail of power-law
wave spectra. The model exhibits dependence of the "electromagnetic bias" on the
radar frequency, an effect observed in field experiments. |
