8 Radar
8.1 Radar: Introduction
The radar (RAdio Detection And Ranging) system has a scanner
mounted on the superstructure and a radar processor box.
The rotating scanner sends out narrow-beam pulses of high
frequency energy then ‘listens’ for echoes as these pulses bounce
back from boats, land masses, buoys, waves, raindrops, birds and
so on. These are known as "targets".
When a pulse is sent, the angle of the scanner gives the direction
of the echo, while the return time of the echo gives the distance to
the target.
Typically, your vessel is in the center of the
Radar screen with
concentric range rings surrounding it. These range rings help you
to quickly estimate the distance to various targets.
You can customize many of the default settings. Some of these
changes apply only to your
Radar screen, but some are global,
meaning they apply to ALL the
Radar screens in your network.
Note: Before using the radar for the first time, some details
must be set up so that the GB40 can configure it correctly.
These details should have been set up by your GB40
installation technician, but you are able to configure them in
the Radar Setup options.
