红外遥感取得的信息,是目标温度T和比辐射率“ε”的多元函数,而ε又是各种目标的特征参量。因此,在遥感信息处理和真实温度测量中,ε是重要的参数。如何在野外用简便的办法直接测得ε值,是遥感基础研究的重要课题。本文讨论了用低温红外测温仪,附加一人工背景辐射装置,用于野外测量8～14μm波段地物目标的比辐射率ε的方法,并对该装置作了简单的介绍。
The information obtained by infrared remote sensing is the multivariate function of the target temperature T and the emissivity “ε”, and ε is the characteristic parameter of various targets. Therefore, ε is an important parameter in telemetry and real-world temperature measurements. How to measure ε directly in the field by simple method is an important issue in the basic research of remote sensing. This paper discusses the method of using the low temperature infrared thermometer with a artificial background radiation device to measure the specific emissivity ε of objects in the 8 ~ 14μm band in the field and gives a brief introduction of the device.
