Popis:	Single IR sensor passive ranging from an observer to a target embedded in the atmosphere exploits the effect of atmospheric attenuation of the signal. By judicious choice of wavebands the range and altitude to a target can be determined passively with a single observer. This result will be shown to be relatively insensitive to assumed atmospheric models or precise source spectral content. A detailed closed-form solution relating range (and altitude) to observed target intensities will be presented. Previous studies of this type have required either detailed knowledge of the source spectra or spectral resolution of individual rotational lines. The single sensor passive ranging methodology requires no such detailed information.
