ELECTRO-OPTICS SYSTEMS PERFORMANCE ANALYSIS IN SELECTED MARINE ENVIRONMENTS.

Techniques have been developed to convert large quantities of previously stored weather products to statistics of specific propagation parameters. The meteorology to propagation parameter models include Lowtran 3B which converts temperature and absolute humidity to absorption coefficients, Naval Postgraduate School semi-empirical models that convert air-sea temperature difference and surface winds to the refractive index turbulence structure function C//N**2, and an aerosol model that uses wind and relative humidity to produce both aerosol size and number distributions and a complex index of refraction. Using a modified Monte Carlo approach that preserves correlations between meteorological parameters, these statistics are coupled to ElO system models in order to calculate the probability of performing various system tasks versus target range in a variety of marine locations. Optical systems in both visible and IR wavelength bands have been studied.
