摘要

本文介绍了一种新型超高分辨率毫米波FMCW合成孔径雷达的设计和工作原理，并利用该雷达进行了波槽实验，研究了SAR图像中内波的成像机理和水面毫米波的后向散射机理。格勒诺布尔的LEGI和汉堡大学的IfM分别用机械产生的波浪和风浪进行了两个系列的实验。考虑到所涉及的散射体的性质，提出并分析了从我们的数据中获得的新结果。结果表明，毫米波雷达对非常小的水动力调制和自由传播的布拉格波敏感。

Millimeter-wave radar back-scattering from water waves

The paper describes the design and operation of a new ultra-high resolution MM-wave FMCW synthetic aperture radar, which has been used for wave-tank experiments to investigate the imaging mechanisms of internal waves in SAR images and the backscattering mechanisms of a water surface at MM-wave. Two series of experiments have been carried out in LEGI, Grenoble, with mechanically generated waves and at the IfM, Hamburg University, with wind waves. The new results we obtained from our data are presented and analysed, considering the nature of the scatterers involved. It is concluded that the MM-wave radar is sensitive to very small hydrodynamic modulations and freely propagating Bragg waves.
