Abstract
The directed energy modeling and simulation community can make important direct contributions to the joint warfighting community by providing the capability to estimate expected performance of high energy laser systems on a worldwide basis over both land and ocean regions accounting for variability in system performance arising from spatial, spectral and temporal variations in operating conditions. Key recently introduced features of theAir Force Institute of Technology Center for Directed Energy’s high energy laser end-toend operational simulation parametric one-on-one engagement level model allow it to meet modeling and simulation needs and function as a near term mission planning tool. These features include the capability to derive vertical profiles of atmospheric effects based probabilisticclimatology,historicalweatherreanalysisgrids,orreal-timeforecastmodelsavailable on-line. Each atmospheric gas or particulate is evaluated based on its wavelength-dependent forward and off-axis scattering characteristics and absorption effects on electromagnetic energy delivered at any wavelength from 0.4 μm to 8.6m. High energy laser end-to-end operational simulation can produce profiles, including correlated optical turbulence profiles in percentile format, from probabilistic climatology for over 400 land sites worldwide for all times of day and for a 1 ◦ × 1 ◦ grid over all ocean locations. In addition, probability of cloud free line of sight for hundreds of land sites worldwide is available in the model. Target surface orientation is defined in three-dimensional space, supporting accurate assessment of the effectiveness of a particular engagement geometry. Effects of thin layers of fog, several types of rain and several types of water droplet and ice clouds can also be considered. In the current study, performance predictions at several wavelengths for a number of geographically diverse land and sea locations are made using numerical weather reanalysis data and are compared with results derived from probabilistic climatology.
