The influence on the return waveform pulse altimeter nonlinear effects of the sea surface waves that lead to deviation of the distribution surface elevations from Gaussian. Demonstrated the limitations of existing models of distributions (including the distribution of the Gram-Charlier) in the analysis of altimetry. It was noted that one of the problems of the simulation of the return waveform pulse altimeter is no model describing the distribution of sea surface elevation on a scale of more than one and a half times that exceed a significant wave height.
Keywords: satellite altimetry, state sea surface, distribution of elevations, nonlinearity of the sea waves.
