Adjusting the radar image
The radar image can be improved by adjusting the gain, by filtering
out unwanted echoes due to sea clutter, rain or other weather
conditions, and by tuning the sensitivity of the radar receiver.
You can adjust the gain, sea clutter, and rain clutter by selecting the
relevant icon in the top right corner of the radar panel or from the
radar panel main menu.
Ú
Note:
The radar image settings do not affect the AIS targets.
Sea and rain clutter can be present at the same time, and further
degradation in detection performance will be experienced. As sea
clutter is related to short range and rain clutter is usually present in a
longer range, rain clutter settings can be adjusted without affecting
the echoes in the sea clutter area.
The radar image can be adjusted as described in the next sections.
Radar modes
Use modes are available with preset control settings for different
environments. Not all modes are available for all radar models.
Custom mode
All radar controls can be adjusted and will be retained after a mode
change or radar power cycle. Radar defaults are set for general
purpose use.
Harbor mode
The radar settings are optimized for areas such as busy waterways
and large man-made structures where good target discrimination
and rapid image updates are needed.
Offshore mode
The radar settings are optimized for offshore sea conditions and
making isolated targets larger and easy to see.
Weather mode
The radar settings are optimized for best detection and presentation
of rain clutter. Image update rate is slowed and color depth is
increased.
