2 Introduction to the Navico Broadband radar system
What is Broadband radar?
The Navico Broad band 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 sends out 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 thermoinic
valve technology. Secondly it transmits continuously, not in pulses and thirdly it measures the time of the echo
not by listening to a received pulse but by varying the frequency of the transmitted signal and detecting the shift in frequency in the received echo. 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 linear 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
Introduction to the Navico Broadband radar system | 5
Preliminary
The difference in the currently transmitted and currently received frequencies, coupled with the known rate of frequency increase, allows a time of flight to be calculated, from which distance is calculated
Benefits of FMCW radar Safer
low energy emissions, similar to a cell phone
more flexibility in placement on boat
can run in anchorages and marinas
Short range performance
Conventional radars can not see anything closer than 30 meters
FMCW can see within a few meters of the boat
See the objects that pose the greatest threat to your boat
Low power
expands market to small boats and yachts
easier install, 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
Convenience – switch it on and use it
6 | Introductio n to the Navico Broadband radar system
Preliminary
Radar system overview
The Navico Broadband radar is a state of the art navigation aid providing outstanding radar performance with out the limitations of conventional pulse radars such as dangerous high power microwaves, Standby warm up time, 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 as an effective range from 1/16 to 24 nm. and has an operating power consumption of 17 W.
The system consists of radar scanner, an interface box and a interconnection cable. The scanner is housed in a dome on is of similar size to most 2 kW radars on the market.
The interface box is used to connect displays and heading information. There are two models (RI-10 and RI-11) depending on the display system used the main difference being one has a SimNet connector for heading input (RI-10). The other interface box (RI-11) 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.
Note Lowrance HDS units sold in the USA do not require an interface box and the scanner connects directly to the display or ethernet switch

3 Install the radar
Installation includes:
mechanical mounting
electrical wiring
configuring the display or network system to work with the radar
adjusting the radar for proper performance
Don't take any shortcuts, and follow these instructions carefully!
This section explains how to:
choose the correct location for the scanner
install the scanner on a power boat or a yacht
choose the correct location for the radar processor
install the radar processor
Check the parts
NEED A BREAK DOWN OF KITS AND UNDER LYING PARTS
8 | Install the radar
Preliminary
Choose the scanner location
The radar's ability to detect targets depends greatly 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 with your radar is usually sufficient. If you think you'll need a longer cable, consult your dealer before installation, because a longer cable may reduce the performance of the radar.
if the roof of the wheelhouse is the highest existing location, consider installing a radar mast or a pedestal on which you can mount the scanner. You may also need to construct a working platform for your own safety during installation and servicing work.
if you mount the scanner on a pedestal or base, ensure that rain and sea spray can drain away from it rapidly.
if you locate the scanner on the mast, position it on the forward side so that there is a clear view to the front of the vessel.
the scanner is usually installed parallel to the line of the keel.
ensure that the location site provides the scanner with a clear view of the front of the vessel.
DON'T DO THIS!
DON'T install the scanner too high up, where its weight will alter the stability of the vessel and 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 finders, VHF antennas, GPS equipment and so on, because it may cause 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 (such as a derrick post) because these vibrations will degrade the performance of the radar.

Preliminary
Mounting the scanner
Use the supplied mounting template and tape it securely to the chosen location site.
Before drilling, check that:
you have oriented the mounting template correctly so that the front of the scanner
-
unit will face the front of the vessel the location site is not more than 15 mm (0.6") thick. If the location site is thicker use
-
longer bolts
Note: The bolts supplied are M8 x 30 mm x 4. If you need to use longer bolts make sure they are 304 stainless steel and allow for 15 mm (0.6") of thread contact
the location site allows the drain hole to empty.
Drill the four holes where shown.
Remove the mounting template,

Preliminary
Mounting the radar interface box
Install the radar interface box in a dry location away from spray, rain, drips and
condensation.
The radar processor must be located where it can be easily connected to the ship's
ground, the scanner interconnection cable, a power source and the display or display network.
Allow enough room for cables to form a drip loop.
Preferably mount the radar interface box on a vertical surface with cables exiting
downwards.
Secure to the surface using the four mounting points

Connect power
Before connecting power to the system:
make sure the scanner has been installed and is secured
make sure the scanner cable is connected to the scanner
if using the Radar Interface Box make sure all connections have been made to the display
The radar system can operate on voltages of 9-32 V DC. The system requires a (+ V DC) to be applied to the yellow remote power on wire in order to operate. This can be achieved by one of three ways.
Common the red and yellow wires together. Radar will power on when power is applied
Install a switch that will provide power to the yellow wire. Radar will turn on when switch
is activated
Connect to the yellow wire to a the external wake up of a suitable display. Radar will turn
on when display is turned on
For systems using a radar interface box
Connect the red wire to power positive 9-32 V DC. Use a 5 amp fuse or breaker
Connect the yellow wire to power source that will turn on the system (see above)
Connect black to power negative
It is recommended where possible to connect the radar interface box to ships ground
