Paper Abstract

The fundamental principles of laser beam detection from atmospheric scattering are well understood and have been used to make successful predictions of received laser power at off-axis detectors. Furthermore, models have been developed that can correlate atmospheric conditions to these predicted received powers. However, in addition to the first-order scattering effects, other "higher-order" effects (multiple scattering, non-spherical aerosols, and optical turbulence) will also play a role in determining the received power and therefore will affect laser beam detection. Using a validated model created by SPAWAR Systems Center, Pacific, an assessment of the relative impacts of these "higher-order" effects is given by model modifications and comparisons with the fundamental prediction. A summary analysis of the "higher-order" effects is presented in an hierarchy, applying each relative contribution to the detection problem.
