In this study we show that spectral and phase-resolving wave models, used for coastal engineering applications, can provide significant differences in the local wave heights and wave power magnitude in the presence of strong bottom-induced refraction. We present here methodologies to compare, in a consistent manner, model outputs to an alternative source of spatial data derived from Synthetic Aperture Radar (SAR) satellite images. Normalized amplitude-derived data are computed from SAR images, compared to both normalized amplitude-derived map from a phase-resolving model outputs and normalized significant wave height-derived map from a spectral model. Two methodologies of SAR images analysis are developed in this paper. While one appears unsuitable due to stochastic wave group modulations, the second methodology provides encouraging similarities between the SAR data and the phase-resolving model outputs.

在这项研究中，我们表明，用于沿海工程应用的光谱和相位分辨波模型可以在存在强烈底部诱导折射的情况下提供局部波高和波功率大小的显着差异。我们在此介绍的方法以一致的方式将模型输出与从合成孔径雷达 (SAR) 卫星图像得出的替代空间数据源进行比较。与来自相位解析模型输出的归一化幅度衍生图和来自光谱模型的归一化显着波高衍生图相比，从 SAR 图像计算归一化幅度衍生数据。本文开发了两种 SAR 图像分析方法。虽然由于随机波群调制而显得不合适，
