Star 2000
The STAR -2000 is an Airport Surveillance Radar from Thales with a modular structure using semiconductor technology . It is used as air surveillance radar for airfields for both civil and military applications. A special weather channel is integrated into the system. The antenna with a Cosecans² diagram is fed by two horn antennas (low-beam = lower diagram and high-beam = upper diagram). However, it is only broadcast in low-beam. The Cosecans² diagram is achieved by slightly lifting the lower part of the parabolic reflector (so-called "lower lip").
The radar device uses the pulse compression method and sends a frequency-modulated pulse with a duration of 75 µs. As the minimum possible range determination is impaired as a result (as long as the radar is transmitting, the receiver cannot receive anything), a short pre-pulse of only 1 µs must be sent to cover this range.
By gradually increasing the transmission power by increasing the number of power modules, the range of the radar can be adapted to the requirements in the range of 60 Nm (111 km) to 90 Nm (167 km). For the STAR-2000 is a standalone Mode S capable monopulse - secondary radar , which is correlated with the data output format of the primary radar.
