Abstract
Within the framework of the Kirchhoff approximation, we derive formulas describing the shift and width of the Doppler spectrum of a microwave signal reflected from a rough water surface in the case of a small incidence angle. The formulas take into account the effect of the radar beam pattern. The new model of the spectrum allows for the fact that the distance from the radar to the observed surface changes in the course of measurements. Our theoretical analysis shows that the Doppler-spectrum parameters and the amount of information on the scattering surface, which is contained in the reflected signal, are strongly dependent on the antenna beamwidth. The results of our study allowed us to develop a new algorithm for measuring the water-surface parameters from a moving carrier.
