6) Go into the Adjust Radar Presets function again.
7) Adjust the auto sea preset value up until most of the weak echoes for an 8Nm
radius are eliminated. Click OK.
8) Adjust the radar range to 1.5Nm and verify that strong echoes from nearby ves-
sels or land are not eliminated. If land or vessel echoes are small or have been
eliminated, follow the above steps to decrease the sea clutter preset.
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 through out 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 elimi-
nated. Click OK .
8) Adjust the radar range to 1/8Nm and verify that strong echoes from nearby ves-
sels 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 through out 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 .
