| 多谱扫描器 | multispectral scanner A remote sensing term referring to a scanning radiometer that simultaneously acquires images in various wavebands at the same time. A multispectral scanner can be carried aboard an aircraft or satellite. The Landsat multispectral scanner records images in four wavebands of visible and near infrared electromagnetic radiation to enable objects with different reflectance properties to be distinguished (一个遥感术语，指扫描辐射计，它能同时获得各种波段的图像。多光谱扫描仪可以安放在飞机或卫星上。在4个可见光和近红外波段的电磁辐射图像中陆地卫星多光谱扫描仪记录，不同对象以反射属性加以区别。) |
