一、前言遥感技术是近年来发展起来的一门新兴的科学技术,顾名思义,遥感就是从遥远的地方对所要研究的对象进行的探测。例如地球资源的遥感就是利用气球、飞机和卫星对地球资源进行的探测。因此,遥感技术的发展是与航空技术和航天技术的发展分不开的。我们知 I. Foreword Remote sensing technology is an emerging science and technology developed in recent years. As its name implies, remote sensing is the exploration of objects to be studied from far away places. For example, the remote sensing of the Earth’s resources is the use of balloons, aircraft and satellites to detect the Earth’s resources. Therefore, the development of remote sensing technology is inseparable from the development of aviation technology and aerospace technology. We know
