摘要
对配置TDI CCD全色相机的光学成像卫星拍摄其他卫星的可行性进行了分析。给出了昴宿星拍摄对Envisat卫星的成像过程。讨论了拍摄卫星和目标卫星的交会方位、距离、速度和光照条件等因素的限制影响。仿真了一轨道高度1 200km光学卫星对美国NROL-66卫星拍摄1年内的交会。研究对TDDI CCD遥感卫星拍摄其他卫星有一定的参考作用。
The feasibility of taking pictures to spacecraft for satellites with TDI CCD sensors was analyzed in this paper. The procedure of the EnvisaCs pictures taken by the Pleiades satellite was presented. The factors of the azimuth, relative distance, relative velocity and incident angle of sunlight condition of the imaging and target satellite were discussed. The simulation sample of a optical satellite with the orbit height 1 200 km taking picture to NROL- 66 satellite in one year was given out. The study was useful for taking pictures to spacecraft for satellites with TDI CCD sensors.
