Description

Next Generation Airport Surveillance Radar

Modular and scalable airport surveillance radar and approach control system for regional and major international airports

ASR-NG is a Multi-Beam 3D S-Band Solid-State Approach Control Primary and Secondary Surveillance Radar and En-Route Control Sensor fulfilling ICAO Annex 10 Volume III/IV and EUROCONTROL Surveillance Standard Requirements. The System implements a fully Digital Doppler Detection and Tracking Solution with most flexible and self-learning Clutter and Site Optimisation Capabilities.
