微型全极化SAR海洋监测应用技术研究

Geographical Situation Monitoring Applications Based on the UAV Airborne SAR

我国作为海洋大国,近年来海洋事业进入快速发展时期,合成孔径雷达以其自身的技术特点在海洋遥感监测中发挥了重要的作用。在以往的海洋监测中大多采用星载合成孔径雷达获取海洋数据,但因星载SAR受到卫星搭载平台和运行轨道等因素影响,对局部地区高时效的数据获取还存在一定的制约因素。本文通过对无人机机载微型全极化合成孔径雷达对海岸带、海岛礁、海洋动目标高分辨率成像和应用分析研究,为无人机机载SAR在海洋监测中的应用提供了全新的技术手段。

As a maritime power,China’s marine industry has entered a period of rapid development in recent years. Synthetic aperture radar has played an important role in marine remote sensing monitoring due to its own technical characteristics. In the past marine monitoring,most of the spaceborne synthetic aperture radars were used to obtain ocean data. However,because spaceborne SAR is affected by factors such as satellite-borne platforms and operational orbits,there are still certain constraints on the acquisition of high-efficiency data in local areas. In this paper,the high-resolution imaging and application analysis of coastal zone,island reef,and marine moving targets are analyzed and researched on the UAV’s airborne miniature fully polarized synthetic aperture radar,which makes the application of UAV’s airborne SAR in marine monitoring provides a brand new Technical means.
