中文摘要: 全极化干涉合成孔径雷达(PolInSAR)是近年来发展起来的一种新的遥感技术,它结合了全极化SAR(PolSAR)和干涉SAR(InSAR)遥感测量技术,能够提高对海洋动力环境和海洋军事环境的遥感探测与监测能力,是当今雷达遥感发展的方向和前沿之一。 目前国内外都在着手进行全极化干涉 SAR 系统这一新一代遥感器的研制,但对全极化干涉SAR 海浪遥感的理论和方法的研究却相对滞后,至今未见公开的报道,这是一项有着重要科学意义和应用价值的前沿研究课题。 本一年期探索项目将从全极化干涉的原理出发,研究海浪的全极化干涉特性以及全极化干涉 SAR 对海浪成像的各种调制作用,并进行海浪遥感仿真与分析,为今后建立全极化干涉SAR 海浪遥感模型打下基础。

英文摘要: Polarimetric interferometric synthetic aperture radar (PolInSAR) is a newly developed remote sensing technology, which combines the full polarimetric SAR (PolSAR) andinterferometric SAR (InSAR) techniques to improve the capabilities of the SAR marine remote sensing. It is one of directions of the development of radar remote sensing. Many countries are engaged in this new generation of remote sensors - PolInSAR system development. But the theoretical and methodological research of PolInSAR ocean wave remote sensing is relatively slow and have not been reported yet. It is a research topic with both scientific significance and application value. This one-year project will focus on the study of the fully polarimetric interferometric properties of ocean waves and the modulations of ocean waves in the PolInSAR imaging processes, based on the principle of full polarization interference. The simulation and analysis of ocean wave remote sensing will be explored for the establishment of the PolInSAR ocean wave remote sensing model in the future study.
