Simrad HALO-3 Pulse Compression Radar

Combining the best characteristics of traditional pulse and FMCW broadband radar systems, our Halo Radar uses Pulse Compression technology to provide an unprecedented mix of long and short detection range, high target definition, and minimal clutter.

Solid State technology means minimal warm-up time and maximum ocean-going reliability, while low-power pulsed transmissions make Halo Radar safe to run in anchorages and marinas.

• Solid-State with Pulse Compression TechnologySimrad 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.48nm RangeHalo Radar delivers a maximum range comparable to traditional 6kW pulse radar, at up to 48nm with the HALO-3 Radar’s 3-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.Beam SharpeningWhether 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 3-foot open array antenna the same effective target resolution as a 4-foot array without beam sharpening.Dual Range OperationWith 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. Target DetectionThe HALO-3 Radar offers excellent target detection for its compact 3-foot open array. For enhanced target detection in line with tough IEC 62388 Annex D specifications, consider our larger HALO-4 Radar or HALO-6 Radar arrays.View comparison tableMARPA 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 ProcessingHalo 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 SelectionCustom, 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.High Speed ModeHalo 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.InstantOnCollision 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.High ReliabilityHalo 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 EmissionsUnlike 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 ConsumptionHalo 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.Ethernet ConnectivitySimrad 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.Uncompromising AestheticsBringing 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.* Halo Pulse Compression Radar’s blue 4 level static accent pedestal lighting may not be approved for use in your boating location. Please check your local boating regulations before turning the blue accent lights ON.**MARPA functionality will not be available on Halo at initial release and will be provided via a software update in Q3 2015.
