Abstract
This paper describes the observation of wave fields by X-band radar at Sumiyoshi coast in Miyazaki Prefecture. Wave propagation was monitored directly from radar images, and two-peak directional wave spectra were obtained. Wave direction acquired from X-band radar agreed fairly well with the measured data from the Doppler-type Wave Directional Meter (DWDM). The correlation was examined between the ratio of radar image amplitude and the significant wave height for dataset classified by local wind speeds.
