Electronics Engineering

The Electronics Engineering Group of the Ultrasound Department specializes in the analog and digital circuit design of customer-specific ultrasound applications for a wide range of applications. 

Compared to industrial and medical ultrasound equipment, active and passive sonar systems typically move in low-frequency ranges (usually from about 50 Hz to about 2 MHz), enabling echoes to be received in water from depths of up to several hundred meters.

Based on the in-house developed, modular multi-channel platform DiPhAS (Digital Phased Array System), which has also successfully established itself in the medical field, a large number of innovative sonar systems have already been developed for a wide range of applications, such as deep-sea research (up to 6000 m depth), mapping of seabed, detection of damage to the base of offshore wind turbines, harbour basins or ship hulls and much more.

The experience of the employees in the design of analog and digital ultrasound hardware covers the entire spectrum of development from concept creation to prototypes and up to market-ready systems. The core competencies of the working group include:

- Feasibility studies, electrical simulations

- Development of customer and application-specific basic concepts

- Design of analog and digital circuits and creation of multi-layer PCB layouts

- Printed circuit board assembly and assembly of prototypes

- Hardware-based programming using FPGAs and µControllers

- Characterization and technical documentation of the system

In cooperation with the software development / system integration working group, complete applications are implemented and developed into customer-specific products.

Our Offer



Research System

The scalable ultrasonic research system "DiPhAS" developed at Fraunhofer IBMT can be adapted quickly and cost-effectively to the most diverse requirements in the field of imaging sonar measurement technology due to its modular design without the need of greater development effort. The platform offers open access to all control parameters and all levels of the signal processing chain.


Multiplexer Development

By using individual multiplexer solutions, the "DiPhAS" ultrasonic research system can be quickly and easily adapted to antennas with up to 1024 elements.


Compact multi-channel sonar systems

For inspection tasks in underwater areas, very large surfaces, such as ship hulls, sheet piling in port facilities or pipelines, often have to be measured with high detail resolution. Multibeam Echo Sounders (MBES), which can analyze defects and record their position, are ideal for this purpose.


Single Channel
Sonar Systems

Our single-channel sonar systems can be used as sediment sonar (sub-bottom profiler), side view sonar (sidescanner) and for obstacle avoidance under water. The number of controllable measuring paths can be extended by suitable multiplexer solutions. Pressure-neutral designs allow the use at sea depths of up to 6,000 m.


1024 Channel
Research System

The availability of real 2D matrix antennas requires growing number of electronic channels. Thanks to the seamless integration of four DiPhAS electronics, 1024 elements can be controlled actively and passively in parallel. This enables volumetric imaging under water in real time, as required, for example, for the inspection of ship hulls or structures.
