为了研究北冰洋等海洋环境，研制了安装在前向避障声纳上的自主水下航行器。为了获得实时、高效、清晰的声图像，采用了声透镜声呐系统。通常，声透镜和光学透镜的设计都是基于几何光学理论。本文采用二维和三维抛物方程方法研究了声透镜的声学特性。
The autonomous underwater vehicle mounted on the forward obstacle avoidance sonar is developed to investigate ocean environments such as that of the Arctic Ocean. In order to obtain real time, high efficiency and clear acoustic images, the acoustic lens sonar system has been adopted. Usually, the design of the acoustic lens as well as that of the optical lens is based on geometrical optics theory. In this paper, the acoustic characteristics of the acoustic lens are studied by using the two- and three-dimensional parabolic equation methods.
