Simrad HALO-4 Pulse Compression Open-Array Radar 4'
Antenna, 20M Cable
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 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.
64nm Range
Halo Radar delivers a maximum range comparable to traditional 6kW pulse radar,
at up to 48/64/72nm with the HALO-4 Radar?s 4-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 Sharpening
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 4-foot open array antenna the same effective target
resolution as a 6-foot array without beam sharpening.
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. Dual Range operation is available with Simrad NSS and NSO
multifunction display systems.
Target Detection
Installed 15m high, the HALO-4 Radar meets tough IEC 62388 Annex D target
detection specifications (excluding beacon and RACON triggering). Installed 3m
high, the HALO-4 Radar offers similar target detection performance to 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.\
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.
InstantOn
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.
High Reliability
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.
Ethernet Connectivity
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.
Uncompromising Aesthetics
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.
*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.
