摘要
为清楚显示卫星瞬时覆盖状况,提出了一种新的二维图形显示普适性算法。根据星敏感器、合成孔径雷达、雷达和扫描敏感器四种常见卫星仪器瞬时覆盖区形状,给出了像素点的解析计算和仿真步长确定的解。对两种典型覆盖仿真结果表明:该算法计算速度快、显示效果好。
To display the instantaneous access area of satellite,a 2-D graphics display arithmetic was put forward in this paper.According to the instantaneous access areas of four usual equipments in satellite which were sensor,synthetic aperture radar,radar and scanning sensor,the solutions of pixel and simulation step were given out.The simulation results of two typical access areas showed that this algorithm was fast and high precision.
