A series of tests designed to quantify the effects of various atmosphere conditions on 2 micron laser radar performance is described. The coherent laser radar system was setup at the Table Mountain Test Facility outside of Boulder. The 2 micron system is operated for the Air Force Wright Laboratory Avionics Directorate by Coherent Technologies, Inc. The system is based on a flashlamp pumped laser that produces 25 mj pulses at a 3 Hz rate. Data on coherent laser radar reveal that aerosol backscatter is directly related to extinction at the laser wavelength considered. Atmospheric conditions have significantly different effects on the ladar performance depending on the application.
