Description

The TIRA (Tracking and Imaging Radar) is an experimental space observation radar system operated by the Fraunhofer Institute for High Frequency Technology and Radar Techniques (FHR). Commissioned in 1970 as a target tracking radar for observing rocket launches, it is primarily used for the development and investigation of radar techniques for space observation. The system incorporates a narrow-band L-band tracking radar, operating at 1333 MHz with a pulse repetition frequency of 30 Hz, a pulsewidth of 1 ms, and a peak power of 1.6 MW, alongside a broad-band (800 MHz) Ku-band imaging radar. Its antenna is a 36-meter diameter Cassegrain parabolic reflector with a 0.45° beamwidth, rotating at 4 rpm, and is protected by a 47.5-meter diameter radome; the movable antenna assembly weighs 240 metric tons.
