遥感技术是一门新技术,在国外,它是首先适应军事需要而发展起来的。当前利用地球资源技术卫星获得的遥感资料,已被广泛应用于地质调查及找矿等各个方面。遥感技术是根据电磁波的辐射原理,使用现代技术中的各种探测器(或叫传感器),在远距离收集待测目标(或地物)所辐射出来的电磁波信息,再经过一系列的技术处理,成象和分析,然后对于所测目标(或地物)进行探测和识别的一门综合性极强的技术。
Remote sensing technology is a new technology that, in foreign countries, was first developed to meet military needs. The current remote sensing data obtained using the Earth Resources Technology Satellite has been widely used in various aspects such as geological survey and prospecting. Remote sensing technology is based on the principle of electromagnetic radiation, the use of modern technology in a variety of detectors (or sensors) in the long-distance collection of the target (or feature) to be measured by the radiation of electromagnetic waves, and then through a series of technical processing , Imaging and analysis, and then the detection of targets (or features) to detect and identify a very comprehensive technology.
