Abstract

Carbon dioxide (CO2) lasers can be used in coherent optical radars. Some CO₂ radars will operate through the Earth's atmosphere. Atmospheric CO₂ and other gases will absorb the laser radiation. Because this is resonant absorption, dispersion will also occur. The combined effects of absorption and dispersion can significantly degrade the resolution of the radar. These effects are calculated in this paper. The particular example chosen for calculation is for a radar that is used to determine the precise range to a satellite in Earth orbit. This example was chosen to show the effects of CO₂ absorption both at low and high altitudes in the atmosphere.
