Abstract
Fourier Transform Infrared Radiometers (FTIRs) are relatively new instruments in the applications of spectral radiometric characterization of targets. One of these FTIR instruments has been modified to provide a modulated spectrum as a source quantity. Interferometric scan signals are transmitted by microwave radio to an infrared receiver downrange in order to synchronize the detection of the modulated signals. The receiver uses the synchronization signals and the modulated infrared signals to obtain a source spectrum after propagation through the atmosphere. The technique appears to give good relative transmission estimates even up to 4 kilometers.
