界面参数估计及传播损失的射线声学预报

Estimation of boundary parameters and prediction of transmission loss based upon ray acoustics

利用射线声学建立的海洋信道模型，根据给定海区声传播实验的实测数据，反演得到界面声学参数，并进行声传播损失预报。预报结果与实验数据比较表明，信道模型正确，界面参数选取与估计方法合理，传播损失预报性能良好。

Estimation of boundary parameters and prediction of transmissioll loss usillg a sound propagation channel model based upon ray acoustics and sound propagation data collected in field experiments are presented in this paper.Comparison between the prediction results and the experiment data indicates that the adopted sound propagation channel model is valuable, both selection and estimation methods on boulldary parameters are reasonable, and the prediction performance of transmission loss is favorable.
