【摘要】 运行于空间轨道的角反射器由于受相对速度的影响,必须进行速差补偿。针对轨道高度为20000km的角反射器,确定了能够接受的直角面平面度;针对几何光学方法速差补偿的不准确,运用衍射原理,对速差补偿的效果按角差的不同进行搜索,得到了比较理想的结果,确定了角反射器的参数。更多还原

【Abstract】 A kind of satellite-borne retro-reflector in 20000km high orbit is optically designed. The far field diffraction patterns of the cube corner prism with flatness error of back faces as well as dihedral angle offsets are computed so that these error parameters are properly determined in order to compensate the velocity aberration. It is shown that result derived from wave optics is different from that of geometrical optics and the physical optics provides the better and more rational approach to designing this cooperative target.更多还原
