Signal-to-Noise Ratio Reduction in Non-Kolmogorov Jet Engine Exhaust Turbulence

Abstract

In a medium experiencing non-Kolmogorov jet engine exhaust turbulence, signal-to-noise ratio (SNR) is evaluated. SNR is naturally degraded due to the presence of turbulence. The reduction in the SNR in non-Kolmogorov jet engine exhaust turbulence is calculated and presented with respect to the power law for various wireless optical communication link and turbulence parameters. The reduction in SNR is referenced to the SNR achieved in the link when there is no turbulence. SNR, being an important entity in determining the link performance, knowledge about the reduction in SNR will help the designers of wireless optical communication links, especially installed in airport environments where jet engine exhaust turbulence mostly occurs.
