- Abstract
Based on the extended Huygens-Fresnel principle, the analytical expression for the cross-spectral density (CSD) function of the radial Gaussian-Schell-model array (RGSMA) beams propagating in oceanic turbulence is derived. Then, combined with the spatial power spectrum of oceanic turbulence, analytical formulas for the average intensity and the root-mean-square (rms) beam width of the RGSMA beams propagating in oceanic turbulence are obtained. The changes of the average intensity and the rms beam width with propagation distance z and three oceanic turbulence parameters, including temperature-salinity balance parameter w, mean square temperature dissipation rate $${\chi _{\text{T}}}$$ , and energy dissipation rate per unit mass $$\varepsilon$$ , are investigated in detail. The results have certain reference value for the propagation properties of the RGSMA beams in oceanic turbulence.
