What is Broadband radar?
The Navico Broadband Radar uses FMCW (Frequency Modulated Continuous Wave) radar
technology.
FMCW radar is di erent:
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 di erence 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.

Welcome | Broadband 3G/4G™ Radar Installation Guide
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 re ects o 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 di erence between both the currently transmitted and received frequencies, coupled with
the known rate of frequency increase, allows a time of ight to be calculated, from which distance is calculated.
Additional bene ts of FMCW radar are:
Safety
• low energy emissions. 1/5th 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 ve times better sea and rain clutter performance
Low power
• suitable for small boats and yachts
• easier installation with lighter cabling and smaller connectors
• great for yachts on ocean passage
Instant power-up
• conventional radars take 2-3 minutes to warm up the magnetron: Safety – 2 minutes is a
long time if you are concerned about collision.
• 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 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 Broadband 3G™ radar has an e ective range from 200 ft to 24 nm, whereas the Broadband
4G™ radar has an e ective range from 200 ft to 36 nm (target dependent).
The operating power consumption for the 3G is 18 W, with a stand-by power consumption of
2 W. The 4G operates on 20W, and has a standby consumption of 2.9W.
The system consists of: radar scanner, an interface box (not included with Lowrance 3G USA
model) and an interconnection cable. The scanner is housed in a dome of similar size to most
2 kW radars on the market.
The RI10 interface box is used to connect displays, power and heading information if MARPA or
chart overlay are required (Heading sensor not included). The RI10 has a SimNet (Simrad NMEA
2000) connector for heading input. The RI10 is included in all 4G kits.
The RI11 interface box is used to connect to earlier NX series displays using a serial connection.
A Y-cable may be used to add heading input for MARPA via NMEA0183.
The 3G kit may be ordered with either interface box, however the Lowrance USA model (00010418-001) is not shipped with an RI10 or RI11 interface.

Choose the scanner location
The radar’s ability to detect targets greatly depends on the position of its scanner. The ideal
location for the scanner is high above the vessel’s keel line where there are no obstacles.
A higher installation position increases the radar ranging distance, but it also increases the
minimum range around the vessel where targets cannot be detected.
When you’re deciding on the location, consider the following:
The length of the interconnection cable supplied w your radar is usually su cient. If you think
you’ll need a longer cable, consult your dealer before installation. Optional cable lengths are 10
m (33 ft), 20 m (65.5 ft) and 30 m (98 ft).
If you mount the scanner on a pedestal or base, ensure that rain and sea spray can drain away
rapidly, and the breather hole in the base can operate .
The scanner is usually installed parallel to the line of the keel.
DON’T DO THIS!
• DON’T install the scanner too high up (eg at the top of a mast), which may cause
degradation of the radar picture over short ranges
• DON’T install the scanner close to lamps or exhaust outlets. The heat emissions may
damage the dome. Soot and smoke will degrade the performance of the radar
• DON’T install the scanner close to the antennas of other equipment such as direction
nders, VHF antennas, GPS equipment, as it may cause or be subject to interference
• DON’T install the scanner where a large obstruction (such as an exhaust stack) is at the
same level as the beam, because the obstruction is likely to generate false echoes and/or
shadow zones
• DON’T install the scanner where it will be subjected to strong vibrations because these
vibrations could degrade the performance of the radar
• DON’T install the scanner such that boat electronics with switch mode power supplies
(such as sh- nders and chart plotters) are in the beam of the antenna
• DON’T install the scanner directly on to a large at roof area. Use a pedestal to elevate the
scanner for radar beams to clear roof line (see “Considerations for direct roof mounting” on
page 8)
Dual Radar installation - Broadband Radar and Pulse Radar installation:
For dual radar installations, ensure Broadband Radar is not installed in the beam of the pulse
radar at any time.

Minimum distance to install near the
ships compass is 0.7 m (3.3 ft).
If possible ensure that the location site
provides the scanner with a clear view
all round the vessel.
Do not install the Broadband Radar on the same
beam plane as a conventional pulse radar. A pulse
radar must be set to STBY or OFF any time the
Broadband Radar is being operated.
Installations on power boats that have a steep
planing angle, it is recommended to tilt the scanner angle down at the front. (Beam angle is 12.5°
either side of center).
Considerations for direct roof mounting
When deciding a suitable mounting location for the Broadband Radar, be aware that the vertical radar beam extends to 25° either side of horizontal. With 50% of the power projecting in a
beam 12.5° o horizontal. If the radar beams cannot clear the roof line, this will decrease performance of the radar. Depending on the size of the hard top of the vessel, it is recommended
not to mount directly on to the surface, instead elevate the scanner to allow the radar beams
to clear the roof line. Below are guide lines on heights above the hard top.

The above illustrates an installation with the Broadband Radar mounted directly on to a large
hard top. This installation could su er decreased performance as the radar energy is either
re ected or absorbed by the hard top.
Note: Where the mounting surface is constructed of any form of metal you must elevate
the dome so that the beam has complete clearance, else performance will be severely
impaired.
