遥感是本世纪60年代蓬勃发展起来的一门新兴的、综合性的高科技探测技术,目前已受到世界各国许多领域和部门的极大关注,在研究和生产应用方面发展迅猛,并显示出强大的生命力和广阔的前景。 一、遥感技术系统 遥感就是以遥远的地方,通过特制的传感器,感知运动着的物质的映象。它借助于专门的光学、电子学和电子光学探测仪器,把遥远的物体所辐射(或反射)的电磁波信号接收记录下来,再经过加工处理,变成人眼可以直接识别的图象,从而揭示出所探测物体的性质和变化规律。所以遥感对勘察研究自然资源、自然环境、侦察军事设施等诸多方面能提供一种十分有效的新的科学工具。
Remote Sensing is a new and comprehensive high-tech exploration technology booming in the 1960s. It has received great attention in many fields and sectors of the world at present, and has been developed rapidly in research and production applications. Vitality and broad prospects. First, the remote sensing technology system Remote sensing is the remote place, through a special sensor, perception of the movement of the material image. It uses a special optical, electronic and electronic optical detection equipment, the distant objects of the radiation (or reflection) of electromagnetic signals received and recorded, and then processed into the human eye can be directly identified by the image, revealing The nature of the detected objects and changes in the law. Therefore, remote sensing can provide a very effective new scientific tool for investigation and study of natural resources, the natural environment and military facilities for reconnaissance.
