Course content

The aim is to give a basic introduction to underwater acoustics. The course covers the acoustic wave propagation, reflection and transmission in fluid media, ray tracing and normal modes methods for solving wave equation; the principle of design underwater acoustic system such as electroacoustic transducers used for generating and receiving sound, sonar and echo sounder and the use of sonar for detection and localization of objects in the sea; signal processing in sonar systems and sonar equations and their applications.

Learning outcome

Knowledge: (a) learn the basic principles for establishing acoustic wave equation; (b) understand the techniques for wave propagation modeling in underwater environment; (c) be familiar with sonar systems for sound generation and reception, localization and classification of objects; (d) understand the basic theory and signal processing tools for underwater acoustic communication and navigation, and acoustic remote sensing.

Skill:(a) model and analyze wave propagation in marine environment using theoretical and numerical models; (b) analyze sonar systems for localization and classification of objects; (c) have the knowledge on acoustic remote sensing of sea bottom structure, composite and oceanographic conditions; General competence: use mathematical and theoretical methods to solve practical problems related to sonar and seismic applications, and underwater acoustic communication.

Further on evaluation

The grade is based on a final written exam.
If there is re-sit examination, the examination form may be changed from written to oral.

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
