摘要：
Measurements of the ocean wave directional spectrum using a dual, high-frequency (HF) radar system are presented. A modelfitting technique is used to obtain wave measurements from the radar Doppler spectra. Over 100 h of data, collected during NURWEC2 (Netherlands-UK Radar Wavebuoy Experimental Comparison), have been compared with measurements using a WAVEC directional wave buoy. The amplitude and directional characteristics of long wave components at frequencies of 0.07-0.1 Hz in general show good agreement. Reasonable estimates of the directional spectrum across the whole frequency range are obtained when the assumptions of the model-fitting technique are appropriate. Remaining problems in radar measurement and difficulties in assessing accuracy are discussed.
