In this paper, the algorithm for sea waves height measurements is developed on the basis of cross-correlation function modulus estimations for reflected signals with frequency diversity. It is shown, that the cross-correlation function is related to the root-meansquare deviation of sea wave heights, the antenna beamwidth, the aircraft flight altitude and the spatial diversity of the transmitting and receiving antennas.
The novelty of this work is to investigate the decorrelation effect of above listed parameters to sea waves height measurement error. A structural scheme has been developed in accordance with which a working model of a two-frequency radar gauge for sea wave height estimation has been designed and manufactured. The results of actual experiments and results, obtained by other authors show the perspective of a two-frequency measurement method at low altitudes.
