Izquierdo, P. e Guedes Soares, C. (2005), “Analysis of Sea Waves and Wind from X-Band Radar”, Ocean Engineering, Vol. 32, N.º 11-12, pp. 1404-1409

This paper presents the performance of a system to analyse images from a X-band radar in order to measure the ocean wave and wind field. In this aim, they are shown the estimations of the directional wave spectrum, the sea-state parameters and wind speed at a location near the Port of Sines in Portugal. Spectral analysis of the time series of radar images is performed to determine directional spectra of the ocean wave fields and also their parameters. The radar calibration to measure ocean waves and the results are presented through a comparison with a directional Waverider buoy located in an area close to the port, evaluating the performance of the system in concerns the determination of sea-state parameters and directional spectra. Here, it is also presented a preliminary study of the capability of this radar to estimate wind fields. In this sense, their calibration to measure wind fields for different angle classes of azimuth directions are also shown.
