中文摘要: 合成孔径雷达(SAR)是先进的微波成像遥感器,自上世纪七十年代第一颗民用SAR卫星发射以来,已在海洋内波等动力过程探测方面开展了大量的应用研究。近年来,随着一系列高分辨、全极化、干涉SAR卫星的发射,SAR技术进入了高分时代。高分辨率、极化、干涉数据的应用使得提取海面的起伏、海面流速成为可能,本项目将通过提取以上内波致海面特征进行内波振幅等参数的反演,发展一种内波SAR探测的新途径。本项研究一方面将提高内波SAR探测的精度,另一方面也为高分、极化、干涉SAR数据在海洋领域的应用提供示范。

英文摘要: Synthetic Aperture Radar (SAR) is an advanced microwave imaging remote sensor. Since last 70's, the first civilian SAR satellite being in orbit, SAR has been widely used in internal waves, ocean waves and other dynamic processes detection. In recent years, several high-resolution, full-polarization, interferometry SAR satellites have been launched. SAR application is now in high resolution era. The application of the advanced SAR data make it possible to retrieval sea surface relief and sea surface current. This project will develop an internal wave amplitude detetion model based on the sea surface feature induced by internal wave. This is a very new approach to internal wave detection. This study will improve the accuracy of the tranditional internal wave SAR detection and provide a demonstration of high-resolution, full-polarization and interferometry SAR data application in oceanography.
