ASR-10SS

ASR-10SS is operating in S-Band solid-state terminal area surveillance radar. The radar satisfies all current ICAO, Eurocontrol and US FAA/DoD surveillance requirements. It is designed for unattended operation, using redundant subsystems with Built-In Test Equipment (BITE) and can be fully controlled and monitored from multiple locations.

The antenna provides cosecant squared pattern and the advantages of high- and low-beam technology. It is usually combined with the COSSOR monopulse SSR antenna.

The radar repeatedly transmits a pulse sequence consisting of 40 pulses, 20 short ones and 20 long ones, differing in carrier frequency (RF) and pulse repetition frequency (PRF). The 20 pulses are transmitted in 4 bursts of 5 pulses each. These 5 pulses in each burst use the same RF and PRF. The long pulses exhibit non-linear frequency modulation.

The radar was built between 1996 and 2008. It was selected by over 15 countries for over 75 sites around the world.
