3.2.8 To get the appropriate image that targets can be easily
observed
To get the appropriate image that targets can be easily observed which requires an
understanding for RADAR signal processing features and an adjustment for the
sea state. All of the parameter can be set indivisually and manually, but it may by
difficult for even expert person.
The sets of signal processing parameters for the general using condition are stored
in FUNC as factory default settings. In most cases, to select the FUNC mode
which fit in the current sea state is lead to get the appropriate image easily and
quickly. So It is recommended to enable the FUNC mode.
Procedures
1) Press [USER] key / Press

bays and coasts where many boats and ships are

: Use this mode to monitor a relatively long range, for example,
the open sea. (Importance is attached to long-range gain.)
: 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
gain slightly lowers.)
: Use this mode when sea clutter is not strong but rain / snow
clutter is strong. (Importance is attached to rain / snow clutter
suppression, and gain slightly lowers.)
i
It is recommended to restore the setting to
the factory default, if you lost the appropriate
