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.

Researchers at Fraunhofer FHR monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere. The scientists at Fraunhofer FHR in Wachtberg near Bonn have already been monitoring Tiangong-1 for a number of weeks with their TIRA (Tracking and Imaging Radar) system, one of the most powerful space observation radars in the world, with a view to supporting the national Space Situational Awareness Center (WRLageZ) and the ESA (European Space Agency) with their re-entry forecasts.

As a member of the Forschungsfabrik Mikroelektronik Deutschland, Fraunhofer FHR will presentits capabilities in designing and testing 3D printed HF components at the Hannover Messe in hall 2, booth C22, from April 23 to 27.


Trade Fair / 25.4.2018

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.


Conference / 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.
