Since 2000, interferometric synthetic-aperture radar (InSAR) has been an effective tool to map 2D water-level changes beneath vegetated wetlands with a high spatial resolution and centimetric accuracy. In the last two decades, SAR images obtained from different wavelengths and polarization modes have been tested across various wetland systems, and InSAR-derived water-level-change maps have improved our understanding of wetland hydrology and hydraulics. In this article, we discuss the feasibility and challenges of applying InSAR to wetland areas, present a comprehensive review of InSAR applications for hydraulic and hydrologic analysis, and discuss future trends.

湿地水文干涉 SAR：方法、挑战和趋势概述

自 2000 年以来，干涉合成孔径雷达 (InSAR) 已成为以高空间分辨率和厘米精度绘制植被湿地下方二维水位变化的有效工具。在过去的 20 年里，从不同波长和偏振模式获得的 SAR 图像已经在各种湿地系统中进行了测试，InSAR 衍生的水位变化图提高了我们对湿地水文和水力学的理解。在本文中，我们讨论了将 InSAR 应用于湿地地区的可行性和挑战，全面回顾了 InSAR 在水力和水文分析中的应用，并讨论了未来趋势。
