Radar sensing is the key to reliable and innovative terahertz solutions. With our comprehensive expertise in RF and antenna design, signal processing, integrated RF circuits, and test and characterization methods, we research and develop powerful, field-ready systems for industry, security, and research for the benefit of society.
System and architecture design for versatile applications: Each application requires an optimal balance of resolution, range, pulse repetition rate, and other parameters. We develop application-oriented solutions with a focus on directly translating scientific insights into practical use.

We offer comprehensive solutions in the development of radar and RF systems that support both scientific and industrial applications and cover the entire process chain:
For the rapid development of demanding industrial, security, and imaging applications, we offer modular FMCW transceiver systems with AI-based signal processing. These systems are proven and on industry-grade maturity level. Thanks to industry-appropriate interface technology, they can be seamlessly integrated into existing platforms. They are flexibly adaptable to specific requirements and offer a compact, scalable solution that is not only cost-efficient but also serves as a basis for further developments, supporting prototype and pre-series development as well as fostering innovations in RF technology.
Our FMCW radars (Frequency Modulated Continuous Wave) provide a powerful basis for a variety of applications in material analysis, non-destructive testing, and security solutions in the terahertz range. By combining SiGe BiCMOS design, antenna integration, and industrial miniaturization, we enable companies to realize innovative solutions that also advance research.
Parameters and backend logic determine which raw data the system frontend must deliver. For custom-tailored systems, we rely on a comprehensive set of RF components and adapt them flexibly—for example, using our innovative 3D antenna printing. Our key building blocks include:
Wireless terahertz systems are ideal for reliably detecting and tracking objects such as sterile goods or machine parts in challenging measurement environments—even under zero-visibility conditions or with reflective metallic targets, where commercial monitoring systems reach their limits. We develop application-specific, complex wireless systems, including RFID systems at 60 GHz, as well as tracking tags compatible with commercial FMCW radar technology.
Wireless or hard-to-access sensors require a reliable and long-lasting power supply, as regular battery replacement is often uneconomical or even impossible. For this purpose, we develop sensors with very low power consumption. They can be operated using energy-harvesting techniques or even completely passively. A high-frequency readout signal provides the necessary energy for operation—maintenance-free, over many years, and robust against temperature fluctuations and changing environmental conditions.
Applications range from automotive technology, where sensors must be designed for the typical vehicle lifetime of 12 years, to structural monitoring, where sensors embedded in concrete must operate reliably for 25 years or longer. Our developments contribute to providing sustainable and long-lasting solutions for various industries.
