Abstract
Using the best available data on atmospheric propagation at different wavelengths, the relative performance of ladar systems using 1.06-mu m, 3.8-mu m and 10.6-mu m lasers has been investigated under various conditions. It appears that except under low visibility conditions the 3.8-mu m systems have the best performance due to the low atmospheric absorption of this wavelength relative to 10.6 mu m and the low aerosol attenuation relative to 1.06 mu m. Lasers radiating at 3.8 mu m with the most efficiency and power are the chemical DF and HC1 lasers.
