Defence

Providing air superiority in complex airspaces, the GM400α (or GM400 Alpha) detects, classifies, and tracks all targets, from low-flying UAS' to high-altitude aircraft, up to 515 km.

LONG RANGE AIR SURVEILLANCE RADAR

Delivering peace of mind in any environment

Superior situational awareness

The GM400α continuously scans the airspace detecting all types of high, medium and low altitude targets. The Identification Friend or Foe (IFF) is activated simultaneously, by leveraging Mode 5 Level 2 interrogations, delivering superior situational awareness and reliability.
Unmatched survivability

Thanks to a truck-mounted operation capability, the GM400α features a very short tactical encamp-decamp time ensuring the highest possible survivability potential for long-range radars.
Ready for the future

The GM400α continuously delivers the highest level of functionality and performance with regular software updates to address new threats, improve Electronic Warfare capabilities and defend against cyber-attacks for today and tomorrow.

BEST-SELLING LONG-RANGE RADAR

With an update rate of only 6s and outstanding processing power, the GM400α shows exceptional tracking capability, even in dense clutter.

Designed to fit into a 20ft ISO container, equipped with a lifting system, and deployable from a truck within one hour, the radar provides rare survivability for a long-range radar.

As a software-defined radar, the GM400α constantly evolves through regular software updates.

Enhanced air situational awareness requires proximity to the battlefield, but this also puts you in the enemy’s direct line of fire. That's why performance, but also superior mobility is crucial for all sensors, starting with long-range radars, to stay agile, survive, and maintain the tactical edge.

KEY FEATURES

The GM400α radar features digital stacked beam technology to have more time-on-target particularly on low-flying targets, allowing enhanced 3D target location accuracy. Operating in the S-band and using advanced GaN technology, it can function reliably, even in extreme temperatures, ensuring robust and accurate performance in diverse operational environments.

With an update rate of only 6 seconds, an elevation up to 40° over a large spectrum of threats, and a combined Mode 5 interrogation, the GM400α by design provides C2 centres with superior situational awareness at all times.

An innovative algorithm provides the best wind turbine mitigation effect, improving detection performance above windfarms.

If survivability contributes to ensuring superior situational awareness, so does operational availability. As a software-defined radar, the GM400α requires minimum maintenance (30 hours/year) and retains high levels of functionality and performance thanks to regular software updates, which address new threats, electronic warfare and cyber-attacks.
