关于遥感技术监测森林火灾能力的估算

The Ability of Remote Sensing Technique for Forest Fire Detection

本文根据林区背景的温度差异,取火场的平均温度,并在假定可以满足识别目标的信噪比的情况下,计算了机载与卫星(NOAA)遥感系统的监测能力。计算结果与实地试验基本符合。因此,利用卫星、机载和地面三个高度层次的遥感资料的相互印证与补充,并加以对照,可对森林火灾进行早期监测。

In this paper based on temperature difference for forest area, average temperature of fire areas and the supposed signal noise ratio is satisfied for discreteness, The detectability of airborne and satellite (NOAA) remote sensing have estimated. The calculated results agree well with field expereiment by remote sensing image checkout. Therefore, using 3-levels (satellite, airborne, and ground) remote sensing can be to complement each other for early surveillance of forest fire.
