SIR-S
(Secondary Surveillance Mode-S Radar)
SIR-S is a Secondary Surveillance Radar (SSR) fully compliant with ICAO and EUROCONTROL recommendations on Mode-S operation. Exploiting Mode-S interrogation, this secondary radar increases its performance in terms of enhanced surveillance functions and supports digital data exchange among ground and airborne computers, implementing ATN (Aeronautical Telecommunication Network) air ground functions, so that any kind of data, mostly kinematics, can be exchanged with the aircrafts in order to improve awareness of target motion, identity, and intention. NEXT has been involved in the SW development of the SIR-S radar data processor, that is the data extractor of the SSR.
