Follow these steps to adjust the Harbor Sea clutter preset:
1. Set the radar range to 1NM.
2. Click and depress the Auto Sea toolbar button.
3. Select the
Adjust Radar Presets
function by right clicking on the radar image window or
from the Radar menu.
4. Set the harbor sea preset to 10. Set the STC Curve preset to 4. Click OK .
5. Manually adjust the gain until you get secondary echoes throughout the image (make
sure your radar color selection allows you discern between strong and weak echoes).
6. Go into the
Adjust Radar Presets
function again.
7. Adjust the harbor sea preset value up until most of the weak echoes are eliminated. Click
OK .
8. Adjust the radar range to 1/8NM and verify that strong echoes from nearby vessels or
land are not eliminated. If land or vessel echoes are small or have been eliminated,
follow the above steps to decrease the harbor sea clutter preset.
STC Curve
The STC Curve function allows you to control the Sea Clutter profile of the radar. By
default, the STC Curve profile is set to a value of 4. For most applications, there
should be no need to change this setting. However, you may want to adjust this
value to get a better application of sea clutter if the radar is either mounted very
high on the vessel, or extremely low. This setting affects all modes of sea clutter
application (auto, harbor and manual).
Follow these steps to adjust the STC Curve profile:
1. Set the radar range to 12NM.
2. Set the gain and sea clutter to manual settings.
3. Setting the STC curve profile to a lower number causes the application of sea clutter to
be focused around the vessel. Setting it to a higher number causes STC to be applied
throughout more of the image. Adjust the STC curve profile value up or down and
observe its impact on the radar image.
4. Select the desired application of the STC curve profile and click OK .
Note
: If the STC curve profile is not set correctly, adjusting the sea clutter
(manual or automatic) may not have the desired impact. If you notice that
increasing the sea clutter control has no impact on the image, your STC curve
