Paper Abstract

Thermal images of natural terrain in the long wavelength infrared (LWIR) are due to thermal emittion of the ground. On the other hand in the short wavelength infrared (SWIR) images there is a contribution of direct sun light due to reflection. The daily evolution of the terrain thermal images with the same thermal properties in both spectral windows were performed using an IR imaging radiometer. The sun reflection and the thermal emmition will affect the correlation between the images. Measurements have shown that the cross correlation goes through a maxima and a minima depending on the sun angle. It seems that the maxima point occurs when the shadow effects are minimal.
