guarantee that interference will not occur in a particular installation.

If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an output on a circuit different from that to which the receiver is

connected.

• Consult the dealer or an experienced technician for help.

• A shielded cable must be used when connecting a peripheral to the serial ports.

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

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

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

*For best chart overlay performance use a heading sensor. Course over ground can be used but
only when moving
