Abstract:

The relative merits of utilizing the 3 to 5 and 8 to 13 micron atmospheric windows for passive infrared reconnaissance have long been debated by the infrared community. In an effort to provide a firm basis for a discussion of this problem, the paper compares the calculated signal-to-noise values to be expected with presently available detectors operating in these wavelength regions as a function of target temperature for three atmospheric paths. The results are discussed in the light of the imagery that has been acquired utilizing the two windows, and conclusions are drawn concerning the source of seeming discrepancies. Finally, recommendations are made concerning the optimization of equipment parameter values for accomplishing specific reconnaissance objectives. Author
