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 scanner which uses the pendulum mirror to scan the track, the compensation of the satellite heading motion can double the scanning frequency and double the scanning efficiency, which is of high practical value. This article focuses on the MODIS-N scan compensation scheme, and its applicability was evaluated.
