What is inside the "ball"?

With its space observation radar TIRA, the researchers at FHR develop new radar techniques for the precise determination of the trajectory, size and form of objects in space. These innovative techniques are also used to check the functionality of satellites, support space missions and monitor the general situation in space.

Research for defense and security

Photorealistic aerial images, high-precision measurements of satellite orbits, a look beneath the Earth's surface,  air surveillance through the utilization of TV and radio stations – just a few examples of the remarkable capabilities of radar. Due to its unique capabilities – independence from weather and daylight, long-range, high sensitivity to range rate changes and the generation of high resolution images – radar is now an indispensable tool for military and civilian applications.

The Fraunhofer Institute for High Frequency Physics and Radar Techniques FHR has focused on the fine-tuning of existing radar systems and the development of groundbreaking new radar technology for over 50 years and has therefore shaped the history of radar for more than half of the time that has passed since it was first patented by Christian Hülsmeyer in 1904.

Defunct satellites: reliably determine and predict attitude motion

Uncontrollable flying objects in the Earth‘s orbit are an enormous risk for active satellites and for spacecraft in general. Since April 2012, the European environmental satellite ENVISAT has also been adrift in orbit. Now, Fraunhofer FHR has developed pioneering methods to precisely determine the attitude rotation of malfunctioning satellites and, thus, to support de-orbiting.


Scientists work together to envision future technologies

Fraunhofer FHR is among thirteen universities, research organisations, and technology companies, to receive a 670 thousand Euros grant to boost research in the field of Nanoarchitectronics (NTX).


New institute management appointed: Dr. Peter Knott and Prof. Dirk Heberling

On August 1st, 2016, Dr. Peter Knott and Prof. Dirk Heberling step in as joint heads of the Fraunhofer Institute for High Frequency Physics and Radar Techniques FHR. Together, they are taking over from Prof. Joachim Ender, who is retiring after successfully leading the institute since 2003.


Sorting black plastics according to type

Recycling black plastics, such as those found in car instrument panels, used to be impossible because their absorption properties made them simply invisible to typical optical analysis systems. But Fraunhofer researchers have developed a new technology that can sort black plastics according to type – and at affordable prices.

Events and Exhibitions


Messe / 20.3.2018

Anuga FoodTech 2018

Impurities of food through plastics or glass often trigger expensive callback campaings. The Fraunhofer institutes IOSB and FHR develop multi sensor concepts for the detection of non-metallic contaminants in products. The institutes are presenting their business activities in hall 4.2, booth D054/D058.



ILA Berlin 2018

 Fraunhofer FHR develops radar systems for observation and reconnaissance of space objects in earth orbits (low earth orbit to geo stationary orbit). The institute presents its space observation radars GESTRA (surveillance) and TIRA (reconnaissance) as well as systems for the detection of UAVs and sensors to be mounted on drones as payload. Fraunhofer FHR is exhibiting together with its partners at the booths of Fraunhofer in Hall 4, Weltraumlagezentrum (Space Situational Awareness Center) in Hall 3 and the Federal Ministry for Economic Affairs and Energy.



EUSAR 2018

EUSAR, the European Conference on Synthetic Aperture Radar, is the world leading international conference dedicated to SAR techniques, Technology and applications. EUSAR has accompanied the worldwide evolution of high resolution imaging radar, both airborne and spaceborne, and has helped to establish an international community of SAR engineers and scientists. As in previous years, EUSAR 2018 will provide a forum for exchanging information and discussion on a wide variety of SAR topics, representing the latest SAR developments.


Konferenz / 20.6.2018

IRS 2018

Organizing the International Radar Symposium 2018 (IRS 2018), the German Institute of Navigation (DGON) and the Fraunhofer Institute for High Frequency Physics and Radar Techniques (FHR) continue a very successful sequence of Radar Symposia. This year, thanks to the close distance between the venue and the site of Fraunhofer FHR, participants can sign up for a tour of the space observation radar TIRA.
