Abstract :
In the moving turbulent ocean, the irradiance fluctuation may depend on both the position and time. In this paper, we investigate temporal statistics of irradiance in the moving ocean with weak turbulence. We present a closed-form expression for the relationship of temporal correlation, propagation distance, and average velocity for the moving medium. We then evaluate the temporal correlation of irradiance in specific turbulent ocean environments. Numerical results suggest that the average velocity is the main factor affecting the temporal statistics of irradiance while link distance has negligible effect, and the temporal fluctuations will increase the temporal correlation while the salinity fluctuations exerts the opposite effects.
