The relative positions of the SceneScan vessel and the Scene
Reference Point can be expressed either as Range and Bearing values,
or as 'A' and 'B' positions on a rectangular coordinate frame.
The position of the tracked scene can be displayed as Range/Bearing/
Heading or A/B/Heading.
Users can select the required mode by clicking the appropriate tab
above the Data Quality area:
Range, Bearing and Heading (R/B/H) mode displays the distance and
the bearing of the Scene Reference Point from the Sensor. The radial
markers around the outside of the BEV are zeroed in line with the
vessel bow and a magenta tag marks the bearing which is the angle of
the target clockwise from the bow.
A purple tag represents the heading, which is the angle of the vessel
bow clockwise from the heading axis.
