星载合成孔径雷达发展现状

Current situation of the development of space-borne SAR

合成孔径雷达(Synthetic Aperture Radar,SAR)是一种主动式微波成像传感器,具有全天时、全天候、高分辨率(数十米至数米)对海探测的特点,可提供海洋及沿岸地区的海面风场、海表流场、海浪、海洋内波和中尺度涡等地球物理信息,具有广阔的应用前景和重要的研究价值。

Synthetic Aperture Radar(SAR)is a kind of active microwave imaging sensors,has a day,allweather,high resolution(tens of meters to several meters)on the characteristics of sea detection,can provide Marine and coastal sea surface wind field,flow field,waves,ocean waves and sea surface mesoscale vortex and other geophysical information,has a broad application prospect and important research value.
