Course lecturers



Introduce students to the basics of sonar system design and skills to reconstruct the surface and image of underwater objects using the sonar signal. Introduce procedures for displaying signal spectrum, digital filtering of 1D and 2D sonar signals, creating 2D and 3D submarine images, designing an antenna or transceiver field, displaying antenna radiation, emitting and wave simulation, sonar image processing, and submarine mining in sonar images.

Course assessment

Conducting university questionnaires on teachers (student-teacher relationship, transparency of assessment criteria, motivation for teaching, teaching clarity, etc.). Conducting Faculty surveys on courses (upon passing the exam, student self-assessment of the adopted learning outcomes and student workload in relation to the number of ECTS credits allocated to activities and courses as a whole).

Overview of course assesment

Learning outcomes
Upon successful completion of the course, students will be able to:

1. define and explain the characteristics of the sonar and its environment

2. describe methods of digital signal processing sonar

3. create a software solution for creating images using sonar

4. validate and compare different methods and sonar models

5. develop and apply different methods and models of sonar in the MATLAB and C ++ programming environment
