Abstract

The optical channel models for airborne submarine laser communication are built and the received energy is discussed. In this propagation channel, sea has the most important impact on the power attenuation. Applying the classical electron scattering theory to the photo scattering effects in the sea, the transmission delay of underwater laser pulse is investigated by small-angle approximation theory, caused by the scattering effects in the sea. To indicate the influences of the seawater properties on the transmission delay, some interrelated curves are displayed. The multi-path time spreading of signal pulse is studied. The waveform of received signals in receiver in submarine laser communication system is analyzed and simulated by use of Monte Carlo simulation. The results deduced by using Monte Carlo coincide with that simulated by using small-angle approximation theory.
