Radar Transmit Emissions
This is the first marine recreational radar that has Human Exposure Level RF Radiation
of the Radar Transmitter outside the Radome well below the general public safety
emission level of 1 mW/cm2. This means the radar can be mounted safely in locations
impossible with other pulse radars.
The broadband radar will not trigger X Band radar transponders, beacons, and SARTs
due to the low output power and signal properties.
If a pulse radar and Broadband radar are mounted on the same vessel, do not
transmit simultaneously as excessive interference is possible.

1Introduction to the Navico Broadband radar system
Welcome
Congratulations of your purchase of the latest technology available in recreational marine radar.
The special features designed into this radar are:
•“Revolutionary improvement in situational awareness” Provides unprecedented ability to
distinguish hazards and other objects
•Radar is finally easy enough for casual users – identifies targets clearly with out
complicated tuning adjustments.
•Navigation with unparalleled resolution and clarity at close ranges, where traditional radar
completely obscures targets.
•“Start faster, go longer” - 100% solid state design – no powerful microwave transmitter
required! – provides InstantOn™ power up capability and low power consumption
•Eliminate the 2-3 minute warm-up time typical of traditional radars
•Conserve power with a standby drain less than one tenth of the best existing radars –
especially great for sailboats and smaller power boats
•No expensive magnetron replacement is ever required
•“Incredibly approachable” - practically imperceptible transmit emissions are extremely
safe, allowing you to mount it anywhere
•Less than 1/10th the transmitted emissions of a mobile phone, can be safely mounted in
proximity to passengers
•Compatible with a wide range of Navico multi-function displays and heading sensors

What is Broadband radar?
The Navico Broadband radar uses FMCW (Frequency Modulated Continuous Wave) radar
technology.
What is FMCW?
The current normal leisure radar generates microwave pulses with a thermionic device called a
magnetron. This ancient technology transmits bursts of high power microwave energy
periodically, and the radar detector listens to the echoes coming back from each pulse. As the
radar rotates, these echoes are built into a 360 degree image.
FMCW radar is different:
Firstly it is solid state – i.e. the transmitter is a semiconductor device, not based on magnetron
technology. Secondly, it transmits a 1ms long signal of increasing frequency, rather than a short
duration pulse. Thirdly, it measures the distance to a target not by timing the returned echoes,
but by measuring the difference between the current transmitted frequency and echoed
frequency. Hence FMCW – Frequency Modulated Continuous Wave.
The building up of the image over 360 degrees and the processing of the radar data is the same
as for a magnetron radar.
How does FMCW radar work?
FMCW = Frequency Modulated Continuous Wave
The scanner transmits a ‘rising tone’ (Tx wave) with linearly increasing frequency. The wave
propagates out from the transmitter retaining the frequency it had when it was transmitted. If it
reflects off an object, it will return to the receiver, still at the frequency it had when originally
transmitted.
Meanwhile, the transmitter continues to output an increasing frequency.
The difference between both the currently transmitted and received frequencies, coupled with
the known rate of frequency increase, allows a time of flight to be calculated, from which
distance is calculated.

Additional benefits of FMCW radar are:
Safety:
•low energy emissions. 1/10th of a mobile phone
•safe operation in anchorages and marinas
•instant power up. No warm up required
Short range performance -
•broadband radar can see within a few meters of the boat, compared to pulse radars which
can not see closer than 30 meters
•higher resolution clearly separates individual vessels and objects
•Up to five times better sea and rain clutter performance
Low power -
•suitable for small boats and yachts
•easier installation with lighter cabling
•great for yachts on ocean passage
Instant power-up -
•conventional radars take 2-3 minutes to heat up the filament: Safety – 2 minutes is a
long time if you are concerned about collision; and
•convenience – switch it on and use it.
Easy to use
•no constant adjusting required to obtain optimum performance
•no re-tuning between ranges. Means fast range change at all ranges.

Radar system overview
The Navico Broadband radar is a state of the art navigation aid. It provides outstanding radar
performance without the limitations of conventional pulse radars such as: dangerous high power
microwaves, standby warm up time, 30 m blind spot (mainbang), high power consumption and
large open arrays - which is what would be required to obtain the same image quality at shorter
ranges.
The Navico Broadband radar has an effective range from 200 ft to 24 nm and has an operating
power consumption of 19 W and stand-by power consumption of 2 W.
The system consists of: radar scanner, an interface box and an interconnection cable. The
scanner is housed in a dome of similar size to most 2 kW radars on the market.
The interface box is used to connect displays, power and heading information. There are two
models: RI10 and RI11. Depending on the display system used, the main difference is that -
one has a SimNet (Simrad NMEA 2000) connector for heading input (RI10). The other interface
box (RI11) has a connector to interface to RS422 displays and NMEA 0183 heading sensors.
Both interface boxes have a Network connector to interface to Ethernet displays.
Lowrance HDS units sold in the USA do not require an interface box and the scanner connects
directly to the display or Ethernet switch

*For best chart overlay performance use a heading sensor. Course over ground can be used but
only when moving
** For MARPA it is essential to use a heading sensor with an output speed of 10 Hz. Heading
sensor needs to be a rate gyro stabilized compass or better.
