The attenuation characteristics of seawater channel affect the laser signal’s transmission distance and receive power.In this paper
according to the coastal ocean of optical characteristics
we analyze the attenuation characteristics of the laser in seawater communications’ channel
and use Monte Carlo method to investigate the transmission process of the laser in seawater channel.Then
we obtain the simulation figures describing the relationship between the transmission distance and received power.We also use Gaussian function to fit the simulation results.In this way
we obtain a theoretical model to describe the relationship between the laser transmission distance and receive power at any position when seawater is impurity concentration.Therefore
we can quickly calculate the receiver power at any locations under certain distances
which provides a theoretical basis for the future design of underwater laser communication system.
