随着科学技术的发展,军事侦察手段也越来越现代化。多光谱(又称多波段),就是现代侦察技术的新秀。在自然界中,由于各种物体的化学成分和物理结构不同,它们对可见光、红外线的反射也各有差异。多光谱技术就是根据这个原理,在同一时间内,对同一目标进行不同光谱带照相或扫描,然后通过对不同光谱数据的分析,辨别目 With the development of science and technology, the means of military reconnaissance are also becoming more and more modern. Multi-spectrum (also known as multi-band), is the rookie of modern reconnaissance technology. In nature, due to the different chemical compositions and physical structures of various objects, their reflection on visible light and infrared light are also different. Multi-spectral technology is based on this principle, at the same time, the same target with different spectral bands or scanning, and then through the analysis of different spectral data to identify
