KUSRAD / Avian Radar

-A +A

The KUŞRAD system, which was developed with the General Directorate of State Airports Authority (DHMİ), is designed to operate uninterruptedly 24 hours a day with a coverage volume of a maximum 40 km range in horizontal axis. It can detect targets and classify them as “Bird”, “Flock of birds” and “Aircraft”. It provides operator(s) target data including target range, altitude, heading, route/trajectory and velocity. The system can be used to track migratory bird movements in critical airspaces around civilian airports to evaluate their treat to safety, and can help in the planning of scheduled flights to reduce accident risk.
