红外波段地球辐射特性的试验研究

Experimental research on earth radiation in IR wave band

地球辐射的范围包括可见光、近红外、中红外、热红外多个波段,不仅与地物的辐射和反射有关,更涉及到太阳辐射、大气传输等多方面,因此各个领域分别从不同的应用角度对其展开了广泛研究.本文首先分析了地球辐射的特点及国内外研究现状,说明了研究地球辐射特性的重要性;然后以截取的某试验数据作为研究对象,主要对近红外波段和中红外波段的地球辐射测量数据进行了研究和分析;通过 Modtran 仿真软件进行理论计算并与测量数据进行了对比;最后总结了此次观测试验研究的意义以及提出了下一步的计划.

The range of earth radiation includes visible light,near inflated,mid infrared,thermal infrared,etc. Because earth radiation relates to clutter radiations and reflections,solar radiation,atmospheric transmission,etc,it has been studied from different angles in many fields.The importance of studying earth radiation is briefly explained by analyzing characteristic and study progress of earth radiation in the paper.Research and analysis of earth radiation's characteristic in near infrared and mid infrared arc researched by measuring data.With Modtran simulating software,numerical value of theory is compared with measuring data.Finally,significance of this experimental research is summarized and next plan is given.
