Experimental Analysis And Modeling Of Optical Turbulence In The Maritime Environment And Its Potential Effect On Laser Communications
Abstract
Free space optical (FSO) communication technology is increasingly used for both commercial and military purposes. For military communication that requires fast, secure, and reliable transmission of information, the benefits of using FSO technology are important. However, there are some inherent limitations, especially due to environmental conditions such as turbulence, that can significantly affect the performance of FSO communication systems. Since turbulence plays a critical role in FSO systems, the purpose of this thesis is to compare different experimental and theoretical methods for estimating turbulence in a maritime environment. This analysis is achieved by measuring meteorological parameters using a local weather station and then using that data to calculate (using machine learning regression analysis) the refraction structure parameter that indicates the severity of turbulence. Also, the impact of turbulence on the signal-to-noise ratio (SNR) for a notional FSO system is estimated to show that even moderate amounts of turbulence can significantly reduce the SNR.
