无人机搭载MiniSAR在养殖用海监测中的应用研究

Research on the Application of MiniSAR Borne by Unmanned Aerial Vehicles in Aquaculture Sea Area Monitoring

传统的卫星遥感监测养殖用海模式,受制于天气和分辨率影响,很难准确监测养殖用海的边界和面积,MiniSAR是一种主动式微小型合成孔径雷达,具有全天时、全天候和高分辨率的优势。通过无人机搭载MiniSAR传感器可以实现对养殖用海区域地物信息的快速获取,提高海域动态监测效率。以江苏省连云港市养殖用海区域为例,通过固定翼无人机搭载MiniSAR,获取了研究区域的高分辨率雷达数据,文章阐述了雷达成像原理,并对试验数据进行了运动补偿、几何校正和滤波处理。最后通过获取的高分辨率MiniSAR图像,提取了养殖用海活动的数量信息与面积统计信息,可以为海域管理部门提供分析决策支持。

Traditional satellite remote sensing monitoring of aquaculture sea mode is difficult to accurately monitor the boundary and area of aquaculture sea due to weather and resolution.MiniSAR is an active microsmall synthetic aperture radar with all-day,all-weather and high-resolution advantages.The Unmanned Aerial vehicle Embarks MiniSAR sensor can quickly acquire the information of the ground objects in the aquaculture sea area,and improve the dynamic monitoring efficiency of the sea area.This paper takes the aquaculture sea area of Lianyungang City,Jiangsu Province as an example,obtains the high-resolution radar data of the aquaculture sea area by using the fixed-wing Unmanned Aerial vehicle Embarks MiniSAR sensor;explains the principle of radar imaging;motions compensation,geometrics correction and performs filtering on the experimental data.and processes the data and extracts the marine culture information.Finally,through the obtained high-resolution MiniSAR images,extracted the quantitative information and the area statistics of aquaculture activities,which can provide analysis and decision-making for the sea area management department.
