16.1 Radar overview
Radar is used to provide information that can help you to track
targets and measure distances and bearings.
Radio Detection And Ranging (RADAR) is used at sea to detect
the presence of objects (known as ‘targets’) at a distance, and if
they are moving, detect their speed.
Radar works by transmitting radio pulses, then detecting
reflections of these pulses (echoes) from objects in the area and
displaying the reflections as targets on your display.
Until you are familiar with interpreting the radar display, every
opportunity should be taken to compare the radar screen
patterns with visual targets, such as other boats, buoys and
coastal structures. You should practise harbor and coastal
navigation during daylight hours and in clear weather conditions.
HD and SuperHD radar
Your multifunction display can be used with radar scanners.
HD and SuperHD radar scanners provide a range of advantages,
making it easier to discern objects around your vessel.
HD and SuperHD radar scanners provide:
• Improved target detection.
• Full-color image.
• Dual Range operation.
• SuperHD option. This effectively increases the transmitter
power by a factor of at least 2, and reduces the beamwidth by
a similar amount.
Note: You must connect a SuperHD radar scanner in order
to use the SuperHD option.
Multiple radar scanners
The multifunction display only supports the use of 1 radar on
the network.
When the radar application is opened, if multiple radar scanners
are detected then a warning message shall be displayed.
Additional scanners will need to be removed from the network
before the radar application will function.
