星载合成孔径雷达图像反演海面风场方法综述

摘要

Synthetic aperture radar (SAR), as a type of microwave radar, can provide all-weather and all-day wind parameters with high spatial resolution and detect sea surface by using multiple bands, multiple polarizations and multiple angles. Meanwhile, SAR can offer the information on the real-time dynamic sea surface with high precision and large area, so further study on SAR is significant. Based on synthetic aperture radar image, this study summarized the new technology and algorithm of the ocean wind retrieval in detail, with the full consideration of wind direction and speed inversion, respectively.%合成孔径雷达作为微波雷达,具有全天候、全天时、高分辨率对海面成像的能力,能实现多波段、多极化、多视角的观测海面,可以提供大范围、高精度的实时动态海面信息,对其进行深入研究有着重要的意义.基于合成孔径雷达图像,分别以风向和风速反演为主线,对国内外海面风场反演的工作进行了详细的总结.
