Three-dimensional scalar characteristics of laser diffusion based on forward-backward method

Aiming at the shortcomings of laser point-to-point communication, the assumption of constructing communication networks by laser diffusion from sea surface was come up with, and the characteristics of the scattered field of laser from perfect conductor surface(PCS) was studied. First, the 3D model of incident laser beam was established with 3D scalar tapered wave. Second, the matrix equation was given and discretized with the method of moments. Finally, the 3D bistatic scattering coefficient was obtained with forward-backward method to accurately express the 3D scalar characteristics of laser diffusion from PCS.
