Tactical and atmospheric coherent laser radar technology
Abstract
CO2 laser radar systems operating in the infrared region are discussed as regards their tactical and remote sensing applications. Coherent and incoherent detection methods for lidar echoes are compared, and the increased sensitivity offered by heterodyne (coherent) detection is demonstrated through an analysis of signal-to-noise ratios. A CO2 TEA laser rangefinder and a small, tripod-mounted CO2 imaging lidar are then presented as examples of tactical applications. CO2 laser radars in use for the airborne detection of clear-air turbulence and wind fields, and for the ground based mobile monitoring of smokestack emissions are also discussed.
