Fraunhofer Institute for High Frequency Physics and Radar Techniques FHRThe Future of Radar Space Observation in Europe – Major Upgrade of the Tracking and Imaging Radar (TIRA)
The Fraunhofer FHR is working on a significant upgrade of the Tracking and Imaging Radar (TIRA) that will revolutionize space observation with radar in Europe. TIRA is one of the largest and most powerful systems for observing near-Earth space and plays a crucial role in measuring and analyzing satellites and space debris.
In recent decades, the use of near-Earth space has dramatically increased, leading to a steadily growing number of active satellites and space debris. Radar-based systems are essential for ensuring safety and sustainability in space, as they can e.g. operate independently of weather conditions. TIRA will be upgraded with a new imaging radar in the Ka-band, significantly improving geometric and radiometric resolution. This new system will make it possible to track, image and analyze objects in near-Earth space satellites with greater precision and a higher level of detail.
"With the upgrade of TIRA, we are taking a crucial step towards improved space situational awareness in Europe. The new possibilities of radar-based space observation with the large radar system TIRA will enable us to adapt to the future challenges of the very dynamically developing situation in near-Earth space and to further increase our capabilities in observing and evaluating the situation in this domain" explains Dr. Lars Fuhrmann, head of section at Fraunhofer FHR.
The TIRA system will not only be equipped with a new imaging radar in the Ka-band, but the tracking radar in the L-band will also undergo a comprehensive upgrade. Through a modular and open design, it will then be possible to update TIRA continuously and adapt the system to the changing demands of space observation. This will allow for e.g. the implementation of new methods and capabilities such as new radar modes and more precise tracking concepts.
A central goal of the project is to enhance the efficiency,adaptability and implementation of radar applications. "The ability to obtain fully polarimetric radar images will enable us to analyze the structures and properties of space objects in even greater detail - an important step for future space reconnaissance " adds Dr. Lars Fuhrmann.
With the upgrade, TIRA will not only tackle the current challenges in space observation but will also become a flexible research instrument with new capabilities for gaining further insights into the state and dynamics of satellites and space debris. The upgrade of the TIRA system will lay the foundation for a new era of radar-based space observation in Europe.
