遥感这个名词是在1960年前后提出的,同年它开始形成一门包括多种技术的综合学科。廿年来,它取得迅速进展,各主要工业发达国家都对它作了很大投资,并为它在八十年代和九十年代的发展拟订了规划。本文的主题——CCD多光谱扫描成像系统,就是计划在八十年代中末期投入应用的新型遥感仪器之一。六十年代初,第一个气象卫星对大气中的云层和地球全景拍摄了简单的电视图像。在图像中可以看到云层的轮廓和相对运动。那时的遥感仪器为了探测较小的温差变化(0.1℃),
The term remote sensing was proposed around 1960, and in the same year it began to form a comprehensive discipline that encompassed multiple technologies. It has made rapid progress over the past two decades, with major industrialized countries making major investments in it and planning for its development in the 1980s and 1990s. The theme of this article, the CCD Multispectral Scanning Imaging System, is one of the new types of remote sensing instruments planned to be put into operation in the late 1980s. In the early 1960s, the first weather satellite photographed simple television images of the atmosphere in the clouds and the earth’s panorama. In the image you can see the outline and relative motion of the clouds. At that time, remote sensing instruments in order to detect small temperature changes (0.1 ℃)
