摘要：

The objective of this work was to develop and validate approaches to accurately and efficiently model channel characteristics in a range of environmental and operational conditions for underwater laser communications systems that use high frequency amplitude modulation (AM) or coded pulse trains. Two approaches were investigated: 1) a Monte Carlo model to calculate impulse responses for a particular system hardware design over a large range of environmental and operational conditions, and 2) a semi-analytic model which has the potential to be more computationally efficient than the Monte Carlo model. The formulation of the Monte Carlo code is presented in this paper, together with test results used to evaluate the range of accuracy of the model against 500ps laser-pulse propagation measurements from well-controlled and characterized particle suspensions in a 12.5m test tank. A multiple scattering study using the Monte Carlo simulation code was also performed and some results are presented. Results from the semi-analytic model will be compared with these test tank measurements and the Monte Carlo model in a later paper.
