Paper Abstract

The statistical and spatial properties of infrared images of ground terrain in the LWIR band were studied extensively, and some generalised models were developed. In this paper we show that some of these models can applied also to the SWIR band. The experimental results, combined with simulation results, demonstrate that there is not any significant difference in the radiative variances of ground terrain images in the object plane, between the two band. In the image plane the results are not compatible with the above stipulations. This dicrepancy is caused bythe differences in signal, atmospheric transmission and system response between the two spectral bands. Thus7 if these effects are not minimized and taken into account, the image obtained will represent reality with a low contrast image.
