Static Blanking Zones
Blanking Zones are used to mask segments of the scan rotation that are obscured by the
vessel’s superstructure. While the scanner passes through a blanking zone, the laser is
switched off to prevent unwanted reflections from interfering with the target data.
Two types of blanking zone can be configured on a CyScan system:
•
Dynamic Blanking Zone
– This is a single sector that can be amended in the
Dashboard when the system is running, even during target tracking. See the Blanking
Zone section of the CyScan Operator’s Guide for further information.
•
Static Blanking Zones – Up to four additional blanking zones may also be configured.
This is done using the CyScan Service Interface and the static blanking zones cannot be
amended via the Dashboard.
Viewing the Static Blanking Zones
The Blanking tab of the CSI displays each of the configured zones and their Start and Stop
angles in degrees. In order to distinguish one zone from another, clicking on a
Show Zone n
button will cause the corresponding zone to be displayed in a different colour, along with the
button itself.
Modifying the Static Blanking Zones
1. Ensure that no target tracking is in progress.
2. Click on the
Take Command button if the CSI is not already In Command mode.
3. On the Blanking tab, click on the Edit button.
4. Amend the blanking zone Start and Stop fields as necessary (if you wish to delete a zone,
set Start and Stop to the same value).
5. Click on Apply to save the changes or on Cancel to discard.
6. Suspend and resume the sensor in order for the changes to fully take effect.
