Atmosphere-ocean laser communication channel simulation and modeling

The method of Monte Carlo simulation based on related theoretical analysis is presented for modeling the atmosphere-ocean laser communication channel. The optical characteristics when laser traverses through atmosphere are addressed by taking molecules and aerosol into consideration respectively. Then the attenuation and time delay spread of laser pulse are analyzed in different channel mediums. Intense Monte Carlo simulations are performed and the results show that the impact of the clouds and the sea water quality on the channel response waveforms is significant in contrast with the impact of atmosphere-ocean interface. It is hard to detect the laser pulse when the weather condition is nimbostratus or the third category of seawater is met. The Mont Carlo simulation results obtained by the paper can be used for wireless optical communication channel modeling and systems design.
