Energy distribution of communication by laser diffusion from sea surface based on forward-backward method

Aiming at the shortcomings of laser point to point communication, the assumption of building the communication networks by laser diffusion from sea surface is come up with according to the need of real sea battle. The energy distribution characteristics of scattered field is studied using forward-backward method(FBM) combined with Green spectral acceleration algorithm (SAA). The accurate 2D laser scattering coefficients from sea surface are obtained and the results are verified by experiments. The results showed that the energy scattered from sea surface are concentrated in the forward zone, less in the backward zone, and attenuated fast in the edges of the scattered field. The feasibility of building communication network by laser diffusion from sea surface among vessels is illustrated. A
