B&G HALO24 Doppler Pulse Compression Radar

B&G's HALO24 Pulse Compression Radar uses innovative VelocityTrack Doppler technology to instantly identify hazards at short and long ranges. Featuring an unbeatable rotation rate of up to 60 rpm, the 24" radar antenna provides near-real-time viewing and optimal visibility for ultimate collision avoidance.

The ultimate view for collision avoidance
The HALO24 radar antenna is incredibly powerful, providing up to 60 rpm of rotation, giving full 360° scanning every second. With these near real-time updates, it gives you the ultimate view and the ability to quickly anticipate possible collisions. In addition, the Halo radar provides crystal clear images that make navigation easier even in poor visibility and densely populated waterways.

VelocityTrack ™ Integrated Doppler Technology
Improve situational awareness and reduce the risk of collision with VelocityTrack Doppler technology! This feature gives you instant visual feedback on whether targets are approaching or moving away. You no longer have to manually select individual targets. The Doppler effect automatically and instantly checks every target seen by your radar. Potential hazards are accordingly highlighted in colour.
