遥感技术是指不直接与目标物接触而远距离感知其性质和状态的一项新兴技术。它的基本原理是:利用物体能辐射、反射电磁波的特性,通过可见光、红外、多光谱、微波和声波等遥感器,从高空或远距离感受来自
Remote sensing technology refers to an emerging technology that remotely senses its nature and state without direct contact with the target. Its basic principle is: the use of objects to radiation, reflecting the characteristics of electromagnetic waves through the visible light, infrared, multi-spectral, microwave and acoustic sensors such as remote sensing from high altitude or from
