Optical propagation in a marine environment: effects of turbulence spectrum choice on simulation

Abstract

Optical propagation in a marine environment is important to understand for many applications. For over ten years, the United States Naval Research Laboratory has maintained a 16 km free space optical link across the Chesapeake Bay at our Lasercom Test Facility. Fundamental models like the Naval Postgraduate School’s NAVSLaM are used to predict turbulence parameters based on weather measurements. Wave optics simulation, using these parameters, is then used to predict scintillation. These predictions are then compared to measurements. ave optics simulation requires an underlying model of the spectrum of turbulence. A variety of turbulence spectra have been proposed, including the Kolomogorov, Von Karman, Hill and Marine spectra. In this talk we compare wave optics simulation, using these spectra, to experimental measurements.
