一台机载或者星载成像光谱仪能够在对地面进行成像的同时,探测由每个像素发射的大范围的辐射波长。目前可以使用的成像光谱仪有四十多种,它们具有一个共同的特征,即每台光谱仪都会迅速地产生过多的数据,这对数
An on-board or on-board imaging spectrometer can detect a wide range of radiation wavelengths emitted by each pixel while imaging the ground. There are currently more than forty imaging spectrometers available that share the common feature that each spectrometer rapidly produces too much data,
