遥感器是遥感技术中最核心的部分,是直接用于测量探测对象的电磁辐射或反射特性的系统。现在,人们已经能够制造多种性能优良的遥感器,而且正在设计更多的能适应不同需要的遥感器. 可见和红外遥感器中的绝大部分是被动式遥感器,即接收目标自身的热辐射或反射太阳的辐射.它的成象
Remote sensing is the most central part of remote sensing technology and is a direct system for measuring the electromagnetic radiation or reflection characteristics of a detection object. Nowadays, people have been able to manufacture a variety of excellent performance remote sensors, and are designing more remote sensors that can meet different needs.Most of the visible and infrared remote sensors are passive remote sensors that receive their own thermal radiation Or reflect the sun’s radiation.
