摘要
基于卫星扫描和地球曲率的几何关系,利用旋转球坐标系的方法,计算了高级甚高分辨率辐射计扫描行中2048点的经纬度,计算结果与卫星数据所提供的经纬度进行了比较,结果表明,该方法可以有效地减小因宽视场的扫描和地球曲率所引起的AVHRR图像的横向比例畸变。
In order to obtain the latitudes and longitudes of AVHRR 2048 points, a method was presented based on transformation of spherical coordinates, and the latitudes and longitudes of 51 points was calculated using the method. The calculated results were compared with the latitudes and longitudes provided by satellite. Results show that this method can reduce effectively the transverse proportion distortion of AVHRR image from the large oblique scan angle and the curvature of the earth.
