Combining the best characteristics of our traditional pulse and 4G broadband radar systems, Simrad Halo™ Radar uses Pulse Compression technology to deliver an unprecedented mix of close and longrange detection, precise target definition, and low clutter.

Solid state technology means minimal warmup time and maximum ocean-going reliability, while compliance with upcoming Low Emission standards makes Halo safe to run in anchorages and marinas.

Find your perfect balance between array size and range

Halo delivers long-range performance comparable to traditional pulse radar, plus unprecedented close range performance down to 6m (20ft) where once only our 3G/4G Broadband Radar could operate effectively.

Watch both nearby collision hazards and faraway weather cells, with Halo’s unique combination of short and long-range performance.

5 Modes with Auto Harbour/Offshore Selection

Custom, Harbour, Offshore, Weather, and BIRD modes tune Halo Radar’s advanced signal processing to help ensure the targets you’re interested in can be seen vividly – even in the toughest environmental conditions. Automatic selection of Harbour and Offshore modes configures your Halo Radar to suit your surroundings, while a ‘Custom’ mode enables easy manual tuning to suit any purpose or condition.

Beam Sharpening with Target Separation Control
Go compact without compromising on resolution. Beam Sharpening grants HALO-3 similar resolution to a 4-foot array, and HALO-4 similar to a 6-foot array.
HALO-6 provides an unprecedented resolution of 0.8 degrees, similar to an 8-foot array.

Advanced Signal Processing for Clearer Images
Halo uses Digital Sidelobe Reduction and Directional Sea Clutter Rejection to enhance the detection and discrimination of smaller targets, while Sector Blanking eliminates unwanted reflections for less clutter on screen.

High Speed Mode for Rapid Position Updates
Halo provides high speed operation up to 48RPM (mode and range dependent). Simrad quality construction and Halo’s brushless motor with advanced helical geartrain design ensure exceptionally quiet operation, especially at high speed.

Dual Range with NSS & NSO evo2 Multifunction Displays
Monitor two distance ranges simultaneously with independent displays, controls, and MARPA tracking. Watch both nearby collision hazards and faraway weather cells, with Halo’s unique combination of short- and long-range performance.

MARPA Target Tracking with 10 Targets per Range
Track CPA/TCPA for up to 10 user-selected radar targets per range (up to 20 total in dual-range mode), when using Halo Radar with a compatible multifunction display, high-speed heading sensor, and GPS receiver.
