HaloTM sees all the way across the bay
From Pax River, HaloTM sees all the way across the
Cheasapeake Bay(1) and detects storms over Cambridge,
300ft and up to 72nm - same time & screen
HaloTM 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)
Track multiple high-speed targets
With high-speed operation, Halo shows target trails of four
fast-moving jet skis in Clearwater, Florida harbour.
Monitor far-away weather cells
HaloTM sees weather cells 65NM away (3), giving you
a real-time view of rough weather long before you encounter
Superior target separation
HaloTM shows clear separation of even the smallest
targets, as seen in this sailing dingy race.
Birds mean fish, and Halo's dedicated BIRD mode means it's
easy to find flocks of birds from a distance. Birds are
visible at 3.5nm here, with no high-gain screen clutter thanks
to Halo Radar's advanced DSP.
Solid-State with Pulse
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 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.
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 3-foot open array antenna the same
effective target resolution as a 4-foot array without beam
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.
The 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.
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.
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.
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
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
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
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
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
* 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.
