Key factors for the design of GAX000 radar, a new generation of UHF Early Warning Radar

Thales SRA (Surface Radars) has launched the development of a new early warning radar family dedicated to the early detection of ballistic missiles (primary mission) and air breathing targets/space objects (secondary missions).The radar is named GAX000 (Ground Alerter) and is available in 3 different versions GA1000, GA3000, GA5000.This publication focuses on the key technical choices in the design of the radar. It first explains the rationale for the development of such a radar and then it describes the Thales experience in low frequency Early Warning Radars. In continuation, this publication describes the key features of the radar, presents the design choices driven by customer operational requirements and by performance requirements.
