New Feature: Velocity Track
VelocityTrack™ technology provides instant visual feedback on the motion of radar targets in relation to your boat. This powerful add-on offers yet another way for Halo™ radar to improve your situational awareness and reduce your risk of collision.
Solid-State with Pulse Compression Technology
Simrad Halo Radar is the world's first high performance, solid-state radar with pulse compression technology designed specifically for recreational mariners. Unlike traditional pulse radar, Halo Radar isn't reliant on a high-powered magnetron (vacuum tube) to transmit. Instead, Halo Radar uses solid-state electronics and low-power 25W pulsed, frequency-swept transmission bursts to deliver pulse radar-like range and resolution, without the associated warm-up time, power consumption, or electromagnetic emissions.
Halo Radar delivers a maximum range comparable to traditional 6kW pulse radar, at up to 72nm with the HALO-6 Radar’s 6-foot open array antenna. It offers unprecedented 6m (20ft) minimum range, peering into that pulse-radar blind spot where once only FMCW (3G/4G) Broadband Radar could operate.

Whether you’re looking at a flock of birds or a string of channel markers, separating one radar target from another is key. Beam Sharpening with Target Separation Control provides unmatched target resolution, granting the Halo Pulse Compression Radar’s 6-foot open array antenna the same effective target resolution as an 8-foot array without beam sharpening.
Superior target separation
Halo™ shows clear separation of even the smallest targets, as seen in this sailing dingy race.
Dual Range Operation
With Dual Range, Halo Radar functions like two arrays in one – monitor two distance ranges simultaneously with independent displays, controls, and totally independent MARPA target tracking. Take full advantage of Halo Radar's combination of short-, mid-, and long-range performance to keep an eye on faraway weather cells, while monitoring channel markers and high speed watercraft up close.
300ft and up to 72nm - same time & screen
Halo™ lets you see near and far in Dual Range mode, with competely independent split-screen displays. Note a remarkably small 20ft main bang area(1)
Installed 15m high, the HALO-6 Radar meets tough IEC 62388 Annex D target detection specifications (excluding beacon and RACON triggering). Installed 3m high, the HALO-6 Radar offers greater target detection performance than our proven Simrad TX06S-1 6kW/4-foot open array pulse radar.

MARPA Target Tracking
Track up to 10 user-selected radar targets, displaying CPA (closest point of approach) and TCPA (time to closest point of approach). Up to 20 different targets can be tracked in Dual Range mode, with 10 targets per screen. MARPA functionality requires a heading sensor and GPS.
Advanced Signal Processing
Halo Radar employs advanced signal processing for digital azimuth and range sidelobe reduction, enhancing discrimination of small targets such as channel markers from larger adjacent targets such as ships and bridges. In addition, Directional Sea Clutter Rejection dynamically changes gain in the sweep to allow smaller targets to be seen in the leeward. Coming soon via free NSS/NSO evo2 software update, Sector Blanking reduces on-screen clutter by eliminating unwanted reflections in up to four user-defined zones.
5 Usage Modes with Automatic 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.
Birds mean fish, and Halo's dedicated birdfinder mode means it's easy to find flocks of birds from a distance.
High Speed Mode
Halo Pulse Compression Radar provides rapid position updates, with high speed operation up to 48RPM (mode and range dependent). Simrad quality construction and Halo Radar's brushless motor with advanced helical geartrain design ensure exceptionally quiet operation, especially at 48RPM.
Track multiple high-speed targets
With high-speed operation, Halo shows target trails of four fast-moving jet skis in Clearwater, Florida harbour.
Collision hazards won’t wait for your radar to start up – why should you? Halo Radar’s solid-state technology is ready instantly from standby, and in just 16-25 seconds from power-on to fully-operational. Avoid the 2-3 minute warm-up time associated with traditional pulse radar, and trust Halo Radar to produce an immediate, accurate radar image when you need it.
Halo Radar is built to last, with its solid-state transceiver meaning no magnetron to replace, and no manual tuning required as the magnetron heats up or ages. Similarly, a solid-state brushless motor driver means no motor brushes to wear out and replace. Be confident that Halo Radar will operate at high speed in winds up to 70 knots, year after year.
Low Electromagnetic Emissions
Unlike traditional pulse radar, Halo Radar transmits low-power pulses. This makes Halo Radar safe to run in anchorages and marinas, providing enhanced radar coverage at the very start and end of each journey. In fact, Halo Radar's minimum safe distance in any transmission mode is within the swing circle of its open array antenna.
Low Power Consumption
Halo Radar uses 40W average with no wind, and no more than 150W at maximum wind velocity. Experience even greater power savings in standby with just 6.5W power usage, versus 10-15W for pulse radar. With its low power consumption and support for 12/24 volt DC systems, Halo Radar is ideal for small to mid-sized powerboats.
Simrad Halo Pulse Compression Radar connects to any Simrad NSS evo2 or NSO evo2 multifunction display system via Ethernet, with a bulkhead-mounted interface box below deck. Antenna installation is simple and elegant, with the same thin cable and small-diameter connectors as our 3G/4G Broadband radars.
Bringing the range and reliability of Halo Pulse Compression Radar to your boat doesn't mean compromising on aesthetics. Halo Radar's sleek open-array antenna sits atop a uniquely curved pedestal, a departure from traditional boxy and utilitarian radar designs. Display your Halo Radar on the water with soft-glow, dual-beam Blue LED accent lighting, integrated into the pedestal and customizable with 4-level brightness control.
