古人说:“不识庐山真面目,只缘身在此山中。”人们在地面只能看到一些局部的事物,而站到一定的高度,譬如太空,则能看到整体,看到由于地面视角的限制而看不到的东西。航天考古就是利用卫星遥感技术,从太空对地球表面进行可见光、红外线和微波辐射的观测,将观测到的信息送入大型计算机,经过数字化图像处理,为人们呈现出一些人们在地面上难以获得 The ancients said: “I don’t know the true colors of my life, but I am only in this mountain.” People can only see some local things on the ground. When they stand at a certain height, such as space, they can see the whole thing. Things that are not visible from the perspective of the ground. Space exploration is the use of satellite remote sensing technology to observe visible, infrared, and microwave radiation from the surface of the Earth. The observed information is sent to a large computer. After digital image processing, it shows people that it is difficult to obtain on the ground.
