The Maritime Security Technologies department is dedicated to addressing a wide range of technological challenges required for the implementation and testing of innovative system concepts for the protection of maritime infrastructures. This includes the development and testing of sensors in the underwater area, in particular active sonar systems.

This position involves the development of methods and algorithms for sonar signal processing as well as the simulation of the underlying acoustic channel. Innovative multiple-input multiple-output (MIMO) sonar systems will be the focus of the research, with complex requirements on the underlying signal processing. Part of the research is the development and practical implementation of improved beamforming algorithms as well as the resulting analysis by means of simulations. Another key focus is on the implementation of efficient back-projection algorithms, which are suitable for near- and far-field applications. The context of the mentioned scientific activities is the underwater monitoring of maritime infrastructures where different acoustic channel properties can be found. Considering the variety of underwater conditions, it is essential to develop sonar systems for specific applications. A further task is to find suitable system specifications for a variety of applications and to design sonar demonstrators for testing under real conditions together with research and industry partners. Existing and resulting systems will also be integrated into into the maritime situation picture of the Institute.

If desired, we will assist the candidate in pursuing a PhD.

Your tasks will include:

• development of methods and algorithms for sonar signal processing
• extension of an existing sonar simulation environment and execution of simulated investigations
• design of sonar arrays for future sonar demonstrators
• experimental testing of developed sonar systems, with comparison to simulated results
• integration into a maritime situation picture
