TIRA
The TIRA (Tracking and Imaging Radar) space observation radar includes a narrow-band tracking radar operating in the L-band and a broad-band (800 MHz) imaging radar operating in the Ku-band. The system serves primarily as an experimental radar for the development and investigation of radar techniques for space observation. It is hosted by the Fraunhofer Institute for High Frequency Technology and Radar Techniques (FHR).
The radar was commissioned in 1970 as a target tracking radar for observing rocket launches.
The antenna is a Cassegrain antenna with a 36 m diameter parabolic reflector. The movable part weighs 240 metric tons. It is protected by a radome of 47.5 meters in diameter.
