3D Long-Range Air Surveillance Radar for UAV Detection

By Phoebe Grinter / 23 Nov 2021

Thales has launched the GM400 Alpha, the latest member of its Ground Master family radar portfolio. GM400 Alpha is an unprecedented 3D long-range air surveillance radar, with 5 times more processing power than the GM400, an extended range of 10% (up to 515 km), upcoming advanced artificial intelligence algorithms and enhanced cybersecurity features.

Leveraging years of successful GM400 field experience, Gallium Nitride (GaN) technology and surveillance capabilities, Thales’ GM400 Alpha allows operators to detect all threats at short and long-range at all times and at all levels.

Featuring digital stacked beam technology, the GM400 Alpha detects targets from fast jets and missiles, to hovering helicopters and Unmanned Aerial Vehicles (UAVs). A unique feature of the GM400 Alpha is the detection and tracking of tactical UAV threats flying close to the ground, hiding in the clutter near the radar, while simultaneously detecting and tracking higher-altitude targets at ranges of up to 515 km.

By applying the latest processing technology, 5 times more powerful, as well as advanced detection algorithms, the radar can process large amounts of complex data. The result is an immediate improvement in detection range, up to 515 km or 278 NM, representing an increase of coverage surface of more than 20% compared to GM400, with no change to the energy required by the transmitter or receiver parts of the radar. 

The increase of processing capacity also provides the opportunity to include upcoming new capabilities using advanced artificial intelligence algorithms as well as enhanced cybersecurity features.

“Already supporting 17 nations around the world, the Ground Master 400 radar family is a reliable and proven partner for air surveillance,” said Serge Adrian, Senior Vice President Surface Radars activities, Thales. “The GM400 Alpha’s software design and processing architecture make it easy to upgrade current fielded GM400 systems, ensuring the radars’ resilience to emerging threats. Some of our customers have already started the upgrade process of their GM400.”
