Fraunhofer Institute for High Frequency Physics and Radar Techniques FHRThe future of space observation lies in multistatic radar systems – and Fraunhofer FHR is the partner to harness this key technology. With the world's leading Tracking and Imaging Radar TIRA, the institute already offers a unique infrastructure that is continuously expanded through strategic collaborations.
First Step: Enhancing Space Situational Awareness Capabilities through Innovative Bi-static Radar Configurations
Bi-static radar configurations enable a significant expansion of the performance of existing space situational awareness systems. This results in higher resolution and more precise object characterization. In addition, the identification of the geometric properties of satellites and space objects is improved. Furthermore, smaller objects can be detected and measured that are only partially or not at all detectable with monostatic systems. Moreover, spatially distributed receiving systems enable extended observation angles, and data quality is significantly increased and made more robust through redundant measurement geometries.
Linking TIRA and the Wetterstein Millimeter Telescope
On the path toward multistatic systems, Fraunhofer FHR, together with Julius-Maximilians-Universität Würzburg (JMU), is realizing an unprecedented bi-static configuration: The space radar TIRA is being linked with the Wetterstein Millimeter Telescope. The telescope, developed and operated by JMU, will be located on the Zugspitze at an altitude of 2,650 m. Its state-of-the-art radio telescope technology, with an investment volume of approximately €4.5 million, will be integrated into the international ngVLA network (next-generation Very Large Array). The system will offer surface accuracy in the micrometer range, enabling measurements of the highest precision, combined with an optimal site elevation for atmospheric transparency and access to networked interdisciplinary research infrastructure.
Enhanced Space Situational Awareness for the Space Industry, Defense, and Research Sectors
By linking TIRA and WMT, an innovative platform is created that offers tailored, enhanced space situational awareness results – for customers including:
- Satellite operators: Detailed attitude assessment analysis of your assets in orbit
- Space agencies: More precise space situational awareness and collision avoidance
- Defense sector: Identification and characterization of unknown objects
- Research institutions: High-resolution data for space debris research
- On-orbit servicing companies: Space object analysis for proximity maneuvers
On the Path to a Multistatic Radar System
The bi-static configuration of TIRA and WMT is just the beginning. Building on this, Fraunhofer FHR is progressively developing a multistatic radar system with multiple distributed receivers to further significantly enhance the performance of space observation. We offer project partners clear technological and strategic advantages. Fraunhofer FHR possesses decades of expertise in radar and high-frequency technology, providing a reliable foundation for demanding development projects. Furthermore, TIRA is available as a global reference system for space observation that can be directly integrated into joint ventures. Partners also gain access to cutting-edge research and the latest technologies, thereby reducing technological risks and shortening development timelines. At the same time, we offer flexible and application-oriented cooperation models for industry, government agencies, and research. In addition, we ensure an efficient transfer structure from fundamental research to operational applications, so that research results can be swiftly translated into usable systems and services.
