This research is directly applicable to the highly-modular HSRL system at NASA Langley Research Center. Subsequent development of this work will result in a system that can validate and extend the current HSRL system. A 532nm implementation of this work will allow cross-validation of the HSRL and PET techniques, as well as add extended capability for temperature, density, pressure and line-of-sight (vertical) wind velocity estimation. The atmospheric measurement capabilities made possible through this research aids in military areas such as atmospheric mitigation for snipers, long-range gunnery and precision landing zones for manned and unmanned aircraft as well as meteorological monitoring to assist in Nuclear/Biological/Chemical (NBC) threat analysis and tracking. Non-military applications include clear-air turbulence sensing for commercial aircraft, meteorological monitoring of tropospheric and upper-atmosphere winds, and site selection and improved efficiency for wind farms.
