3.11.3 Overview of Function Operations
The following outlines the operation of each function selected from the function setting menu:
[Page 1] [1] MODE (Mode)
•
Selects the function name to be indicated at the lower left of the radar display when the function is
selected.
•
When the setting is changed back to the factory setting, the initial value of the selected mode is
called.
•
The following 11 modes are provided:
COAST: Use this mode to monitor a relatively short range, for example, bays and coasts
where many boats and ships are running. (Importance is attached to resolution.)
DEEPSEA: Use this mode to monitor a relatively long range, for example, the open sea.
(Importance is attached to long-range sensitivity.)
FISHNET: Use this mode to detect small targets such as fishnets of round haul netters hidden
by sea clutter returns. (Importance is attached to sea clutter suppression, and
sensitivity to moving targets lowers.)
STORM: Use this mode when many rain/snow clutter returns or sea clutter returns are
detected in stormy weather. (Importance is attached to rain/snow clutter and sea
clutter suppression, and sensitivity slightly lowers.)
CALM: Use this mode when only a few rain/snow clutter returns or sea clutter returns are
detected.
RAIN: Use this mode when sea clutter is not strong but rain/snow clutter is strong.
(Importance is attached to rain/snow clutter suppression, and sensitivity slightly
lowers.)
BIRD: Use this mode to detect tens of seabirds at low altitude during coastal navigation
or hundreds of seabirds at high altitude during ocean navigation.
LONG: Use this mode to detect small targets at relatively long distance in the open sea.
BUOY: Use this mode to detect small targets like radio buoys in areas outside the sea
clutter area. (This mode displays targets of which detection probability is low.)
USER1: General mode used when the nine modes above are not applicable
USER2: General mode used when the nine modes above are not applicable
