利用浅水地形及其SAR影像确定海面风向的一种方法

A method to detect wind direction of ocean surface by using shallow water topography and its SAR image

利用浅水地形的SAR影像以及基于浅水地形SAR仿真模型计算得到的仿真SAR影像,基于仿真SAR影像与真实SAR影像之间的相关性提出了一种确定海面风向的方法——最大相关系数法.以南沙双子礁海域为例,利用最大相关系数法确定出了一幅RADARSAT SAR影像成像时刻的海面风向,通过对结果的比较分析可以看出对于包含浅水地形的SAR影像应用该方法探测海面风向是可行的.

SAR images include information of wind field of ocean surface. A new method in which the maximum correlation coefficient method was used to determine the wind direction of ocean surface was presented. This method uses shallow water topography, its SAR image and its simulation SAR image which was obtained by using the shallow water topography SAR image simulation model. The ocean area of Shuangzi Reefs in the Nansha Islands was taken as an example and the wind direction of ocean surface was analyzed by using one scene RADARSAT SAR image. The results show that the method which is used in wind direction detection with the SAR images of shallow water topography is practicable.
