With its radar-on-chip technology, Fraunhofer FHR has now opened up the advantages of radar for use in robotics as well, proving this with the EU project Smokebot. This project, conducted by international partners from research and industry as well as future users, developed a mobile robot capable of providing valuable information to emergency forces by remote control or even semiautonomously. For this, Fraunhofer FHR supplied the small radar modules, which are highly efficient in terms of energy consumption and data volumes, allowing for high-resolution 3D obstacle detection even in poor visibility. The Smokebot prototype will be tested under real operating conditions in the fire exercise building of the Dortmund fire department at the end of June 2018.

Every year, experts from around the world exchange the newest insights in radar research at the International Radar Symposium IRS, opening up this promising technology for modern applications such as autonomous driving. In 2018, the symposium organized by the German Institute of Navigation (DGON) and the Fraunhofer Institute for High Frequency Physics and Radar Techniques FHR will celebrate its 20th anniversary in Bonn. The four-day symposium chaired by Prof. Dr. Peter Knott, Executive Director of Fraunhofer FHR, kicked off yesterday with a visit to the institute in Wachtberg und its highly visible space observation radar TIRA.

Radar images of the Earth from the air or space or images of objects in space offer unique advantages: high-resolution images can be created at a distance of hundreds of kilometers – irrespective of weather and light conditions. 500 experts will meet this week to exchange scientific knowledge at EUSAR (European Conference on Synthetic Aperture Radar) in Aachen.

The researchers at Fraunhofer FHR are currently developing an innovative radar system on behalf of the Space Administration of the German Aerospace Center (DLR). On completion, the system will allow 24/7 observation of near-Earth space. When put into operation at the German Aerospace Center in mid-2019, GESTRA will supply space object-related data that was previously not available – a milestone in space observation in Germany. Learn more about the new system at ILA Berlin from 25-29 April 2018.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to high-precision orbital data for the largest possible number of these objects are in a better position to plan evasive maneuvers and prevent destructive collisions. From the 25th to the 29th of April 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin Air Show: Hall 4, Stand 202 (Fraunhofer-Gesellschaft), Hall 3, Stand 302 (German Space Situational Awareness Center ) and Hall 2, Stand 203 (Federal Ministry of Economic Affairs and Energy).

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h. Currently the prognosis relating to the time of impact currently lies within a window of several days. 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 German Space Situational Awareness Center (WRLageZ) and the ESA (European Space Agency) with their re-entry forecasts.

3D printing is becoming increasingly important for the development of modern high frequency systems as it opens up new design possibilities. Fraunhofer FHR is exploring these possibilities for its customers and partners: from designing new HF components to testing these components. Engineers are inspecting the quality of components manufactured using additive processes with their high frequency transmitted light imaging system SAMMI®, e.g. to verify the correct density gradients of the material. As a member of the Forschungsfabrik Mikroelektronik Deutschland, they will present this system at the Hannover Messe in hall 2, booth C22, from April 23 to 27, 2018.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.

Time and again, food contamination from materials such as plastics and glass leads to costly recall campaigns. The Fraunhofer Institutes IOSB and FHR develop multi-sensor concepts to detect contaminants in products. They will present these concepts along with the rest of their service range at the Anuga FoodTec in hall 4.2, booth E054/D058.

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, the Fraun-hofer Institute for High Frequency Physics and Radar Techniques FHR has developed pioneering methods to precisely determine the attitude rotation of malfunctioning satellites and, thus, to support de-orbiting missions in the future.
