摘要
在以摆镜为穿航迹扫描的光机扫描仪中,卫星航向运动的补偿使扫描频率降低一倍,并使扫描效率提高一倍,从而具有很高的实用价值。本文重点讨论了MODIS-N的扫描补偿方案,并对它的适用性进行了评价。
In the optical-mechanical scanner which uses an oscillating mirror to scan cross tracks, the correction of spacecraft motion can decrease the scan frequency and increase the scan efficiency by a factor of 2, respectively. This is very valuable. The MODIS-N correcting concept and its application axe discussed in this paper.
