摘要
卫星获取遥感图像的过程是与时间T有关的动态过程,在动态情况下获取的图像数据可以用动态的空间方位投影来描述。研究适合描述这些图像数据的空间斜方位投影,导出卫星星下点轨迹投影公式和空间斜方位投影公式,并研究投影变形情况,最后给出算例。
The process of obtaining remote sensing images by satellites is a dynamic process that relating to llme t, the image data obtained under the dynamic condition can be described by the dynamic spaee oblique azimuth projection. In this paper, the space oblique azimuth projection that adapted to describe the image data is researched, it＇s formula is deduced, it＇s distortion is analyzed. The ground track projection is also deduced accordingly. Calculating examples is presented in the end.
