不同的地质体吸收、反射、发射和透射电磁波的波长与频率是不同的,这是由各种地质体物质成分、结构和分布格局上的差异造成的。因此可以说,地质体电磁波辐射的特点,是反映地质体总特征的灵敏指示剂。卫星象片是地表景观电磁波辐射总特征的综合反映,而地表的景观现象多受地质构造的控制,同时,我们还可以对不同季节、不同波段的象片进行处理和分析对比,以排除非地质信息的干扰,使地质体或地质构造信息以较明显的色调异常或图形异常出现在卫片上,以便有效地解决不同地质体的界线和地质构造特征等一系列问题。而明显呈线性延伸的异常带——通常称之为线性构造——则多
The wavelength and frequency of absorption, reflection, emission and transmission of electromagnetic waves by different geologic bodies are different, which are caused by the differences in composition, structure and distribution pattern of various geological bodies. Therefore, it can be said that the characteristics of electromagnetic radiation of geologic bodies are sensitive indicator of general characteristics of geologic bodies. Satellite imagery is a comprehensive reflection of the general characteristics of the electromagnetic radiation on the surface landscape. The landscape phenomena on the surface are mostly controlled by the geological structure. At the same time, we can also process and analyze the images of different seasons and different bands to exclude non-geological Information interference, so that the geological body or geological structure information more obvious hue or graphic abnormalities appear in the patch, in order to effectively solve the boundaries of different geological bodies and geological characteristics of a series of issues. The anomalous bands, which are obviously linear extensions, are often called linear structures
