A three-site short-range (25 MHz) CODAR SeaSonde High-Frequency (HF) radar system has been operating in the Gulf of Naples (Tyrrhenian Sea) since 2004. HF radars use first-order echoes to determine surface currents, while second-order ones can be exploited to estimate the main parameters characterising the wave field: significant wave height, direction and period. Waves were studied in the Gulf of Naples at each radar site over a range cell located between 5 and 6 km from the coast. The data acquired in the reference year 2010 were compared with the measurements recorded over the same period by a directional wave buoy installed in the outer part of the basin. This study aims at verifying the agreement between the recordings of the two platforms, in order to test the robustness of the HF radar-derived wave measurements. In addition, the analyses here presented investigate the seasonal patterns of the wave parameters, showing the different responses of the wave field in different sectors of the basin and the responsiveness of HF radars in critical environmental conditions. The two platforms showed consistent results, indicating the reliability of HF radars as wave measurement tools and opening the way to further applications in wave monitoring and analysis in coastal areas.

自2004年以来，那不勒斯湾（第勒尼安海）一直使用三站式短程（25 MHz）CODAR SeaSonde高频（HF）雷达系统。HF雷达使用一阶回波确定地表电流，第二次使用可以利用阶次参数来估计表征波场的主要参数：重要的波高，方向和周期。在那不勒斯湾的每个雷达站点上，在距海岸5至6公里之间的一个测距单元上研究了电波。通过将基准年2010年采集的数据与安装在盆地外部的定向波浮标与同期记录的测量值进行比较。这项研究旨在验证两个平台的记录之间的一致性，以测试高频雷达衍生波测量的鲁棒性。此外，此处进行的分析研究了波参数的季节性模式，显示了流域不同区域中波场的不同响应以及在关键环境条件下HF雷达的响应。这两个平台显示出一致的结果，表明HF雷达作为波浪测量工具的可靠性，并为进一步应用于沿海地区的波浪监测和分析开辟了道路。
