摘　　要：针对卫星侧视雷达图像的空间地图投影问题,为卫星侧视雷达图像设计了一种空间斜圆锥投影(SOC),作为这类图像数据的动态数学基础。首先考虑空间斜圆锥投影的几何模型,依据该几何模型建立侧视区域中心线轨迹投影,进而导出空间斜圆锥投影公式,并讨论了投影变形,最后以海洋卫星为例求得一种空间斜圆锥投影模型。The problem of space map projection of side-glance radar imagery of satellite is researched. As the dynamic mathematical foundation, a kind of space oblique conic projection （SQC） is specifically designed for the side-glance radar imagery of satellite. The geometric model of SOC is considered firstly, and the ground track projection of the central line of side-glance region is established secondly based on this model, and then the formula of space oblique conic projection is deduced and the projection distortion is discussed. As an example, the side-glance radar imagery data of ocean satellite is considered, and a special space oblique conic projection model is obtained finally.
