Table View
By default, this displays the positional data for all of the currently chosen sensors, in the
form of a table. For each sensor this comprises:
•
Range : The measured distance to the object detected by the sensor. The background
of this field is coloured according to the range value:
Red for ranges below configured red alarm limit
Amber for other ranges below configured amber alarm limit
White for longer ranges or if no measurement is made
•
Signal Strength : Represented by filled segments of a bar chart and – if the cursor is
moved over the chart - numerically in the tooltip.
•
Speed: This is calculated from the most recent range measurements and marked as
“Closing Speed” if the sensor is approaching the object and “Separating Speed” if
moving away.
•
Time to Contact: How long it would take for the vessel to make contact with the
detected object, based on the currently-displayed closing speed. Displayed as a
number of seconds or as “> 1 min”. In the case of a separating speed, the field
contains “---“.
Each row in the table contains a Profile button, which replaces the positional values for a
sensor with a Profile plot:

This represents the signal returned at each range – a large vertical peak means that an
object exists at the range shown by the horizontal axis.
The buttons along the top of the graph allow you to choose the way in which the system
interprets the received signals.
