Paper Abstract

Atmospheric modulation transfer function (MTF) measurements in both thermal imaging atmospheric windows are presented for the first time to the best of the authors' knowledge. Surprisingly, results indicate significant angular spatial frequency dependence of the MTF, in contradiction to the conventional approach which refers to atmospheric attenuation only. A theoretical explanation is discussed, based upon aerosol forward scattering and absorption effects, which are shown to be angular spatial frequency dependent and yield MTF results similar to those measured.
