本文着重阐述并改进了高频海洋学雷达对海浪高度的估计。来自WERA高频雷达的三个月采集数据与在各种海况下的Datawell MarkIII定向乘波浮标数据进行了比较，根据各种误差源解释了雷达衍生波高的大时空变化，该误差明显大于先前报道的数值。对提高有效波高的平滑和滤波方法进行了评估，结果表明主要误差源来自于外部射频干扰。对消除干扰的特征分析和基于模型的方法进行了评估。本文对二阶雷达海洋散射方程进行了综合总结，并对相关各项进行了评估。

This thesis focuses on explaining andimproving the estimation of ocean wave heights from high-frequencyoceanographic radar. Three months of data from a WERA HF radar is compared to aDatawell MarkIII directional waverider buoy, under a wide range of sea states.Large spatial and temporal variation in the radar-derived waveheight,significantly greater than previously reported, are explained in terms ofvarious error sources. Averaging and filtering methods for improving thesignificant waveheight are evaluated, and the dominant error source is shown tobe external radio frequency interference. Eigen-analysis and model-basedmethods are evaluated for the removal of interference. A comprehensive summaryof the second order radar-ocean scattering equations is given, with evaluationof its terms.
