Abstract

For the study of the environmental characteristic parameters of typical ocean weak turbulence field, such as temperature and salinity concentration, the intensity distribution of the Gaussian beam propagation in ocean weak turbulence has been obtained by using the temperature-salinity coupling refractive power spectrum model and the theory of random phase screen, and the intensity characteristic has been analyzed by the two-dimensional gray histogram. The simulation results show that the turbulence intensity is an influence on the image characteristic, which contain the brightness and the non-uniformity degree of the image, and the effects of the variable average temperature on the image characteristics are stronger with the increase of the turbulence intensity, and then the effects of the variable average salinity concentration on the image characteristics are small under the typical weak turbulence conditions.
