Surface Movement Radar ASTRE 2000
The Surface Movement Radar ASTRE 2000 is (or was) installed at the locations Athens, Berlin-Tegel, Dublin, Edinburgh, Heathrow, Milan, Moscow, Orly, Prague, Stansted, Vienna and others.
The radar uses a parabolic reflector antenna with an inverted cosecant squared diagram. It is a frequency diversity radar with two independently operating transmitters/receivers. The signal processing is also duplicated and every channel has a second signal input for the other one channel. A remotely operated switch selects the video of one of the channels for display. The output signal to the remote display units is a multiplex signal on a coaxial line with the individual and sum video as well as the synchronous pulses.
Later the Radom and the ASTRE 200 was decomposed on the control tower Berlin- Tegel (TXL) visibly over a long distance. Instead of this one, a Scanter 2001 SMR antenna was installed.
