Significant advancements in underwater acoustic communication have been achieved in recent decades. In the dynamic ocean environment, various physical processes can significantly affect the communication channel. The time-varying underwater channel has both deterministic and stochastic features. Due to the dynamic environment and the complex properties of the channel, it is extremely challenging to predict or model the channel. A communication channel simulator is developed through the use of parabolic equation modeling of acoustic propagation and scattering. The simulator uses the acoustic parabolic equation model augmented with a linear surface model. Our results show that this model is capable of generating realistic channel characteristics. Our on-going effort is to reduce the computational cost of the acoustic channel simulator so that it can be used for network simulations.
