Abstract
The analysis of HF dual-radar wave measurements taken during the NURWEC2 experiment indicates that the method used to invert radar Doppler spectra overestimates energy at very long ocean wavelengths (>400 m). This overprediction of energy can be mainly attributed to the effects of shallow water. The authors develop and discuss modifications necessary to account for the effects of shallow water in the simulation and inversion of radar Doppler spectra. The results illustrate the effect of shallow water processes on the radar Doppler spectrum and the improvements obtained in inverted directional wave data when they are accounted for
