In. Klepikov et Ea. Sharkov, THEORETICAL-STUDY OF THE NATURAL RADIATION OF HIGHLY NONUNIFORM NONISOTHERMAL MEDIA, Soviet journal of remote sensing, 10(6), 1993, pp. 969-989
A closed-form solution is obtained for the thermal radiation of determ
inate stratified nonuniform nonisothermal media with arbitrary absorpt
ion, taking into account interference effects. Thermal radiation spect
ra are analysed numerically for a number of typical cases of nonunifor
m nonisothermal media.
