The Fraunhofer Institute for High Frequency Physics and Radar Techniques FHR develops concepts, methods and systems for electromagnetic sensor technology, particularly radars, implementing modern methods of signal processing and innovative technologies, ranging from microwaves to the lower end of the terahertz band. With a budget of €32.5 million in 2015 and more than 300 employees, Fraunhofer FHR is one of the largest radar research institutes in Europe.
Radar and related high-frequency systems form a key technology for defense and security, particularly in the field of reconnaissance and surveillance. FHR has supported the German Ministry of Defense in this field since the foundation of the institute in 1957. In Germany, the institute has played a pioneering role in the development of new technologies for numerous applications: e.g. space reconnaissance with radar, multi-function radar systems with phased array antennas, adaptive interference suppression, millimeter wave techniques, ultra-high resolution radar imaging, moving target recognition with space-time filtering, target classification and passive radar.
The most valued competencies of Fraunhofer FHR – numerical calculation of electromagnetic fields, high-frequency technology and sensor signal processing – enable the institute to design, develop and implement complex high-frequency systems, executing each step in-house. Fraunhofer FHR unites leading edge technology with sophisticated methods of signal processing to devise new types of system. This is accomplished by the interdisciplinary collaboration of physicists, engineers and mathematicians. The activities in the business units Defense, Space, Traffic, Environment, Security and Production constitute concrete examples of innovative applications that are being implemented in many areas of society.
