Average intensity of M x N Gaussian array beams in oceanic turbulence

Based on the power spectrum of oceanic turbulence proposed by Nikishov, the analytical expressions for average intensity of M x N Gaussian array beams propagating in oceanic turbulence are derived, where the coherent and incoherent combinations are considered. Using the focused beam, the intensity can be received at the same point. The changes of the average intensity versus three oceanic parameters are investigated. (C) 2015 Optical Society of America
