:
True Motion. A display across which the own ship and targets move
with their own true motions.
:
To Waypoint (To WPT)
:
Tracks displayed by the radar echoes of targets in the form of an
afterglow
:
A graphical simulation facility used to assist the operator to perform a
proposed manoeuvre for navigation and collision avoidance purposes
:
A vector representing the predicted true motion of a target, as a result
of input of the course and speed of the own ship

Target Tracking
:
Time To Go. Time to next waypoint.

:
A target representing the automatic or manual activation of a sleeping
AIS target for the display of additional information
:
A target simultaneously representing a tracked target and a AIS target
which are decided as the same
:
A type of transmission waveform with intra-pulse frequency
modulation used by solid-state radars. Its radio wave type is classified
as Q0N.
:
Unwanted reflections on a radar screen, from sea surface, rain or
snow.
:
Screen displayed on the LCD
The range of variation of the Q0N frequency used for transmission
waves of a solid-state radar. Generally, the greater the frequency
deviation range, the higher the resolution in the range direction.
:
A device to switch over two or more radar display units and two or
more radar antennas
:
Line between two consecutive waypoints
:
A target symbol representing the last valid position of an AIS target
before the reception of its data was lost, or its last dead-reckoned
position.
:
One for which target information is no longer available due to poor, lost
or obscured signals.
:
A radio frequency amplifier circuit consisting of semiconductor
elements used for solid-state radars. It employs a high frequency, high
power FET.
:
Main positioning sensor
