xviii
TM
: True Motion. A display across which the own ship and targets move
with their own true motions.
To WPT
: To Waypoint (To WPT)
Trails
: Tracks displayed by the radar echoes of targets in the form of an
afterglow
Trial manoeuvre
: A graphical simulation facility used to assist the operator to perform a
proposed manoeuvre for navigation and collision avoidance purposes
True vector
: A vector representing the predicted true motion of a target, as a result
of input of the course and speed of the own ship
TT
: Target Tracking
TTG
: Time To Go. Time to next waypoint.
TXRX
: Transmitter-Receiver Unit
UTC
: Universal Time, Coordinated
VRM
: Variable Range Marker
VDR
: Voyage Data Recorder
WOL
: Wheel Over Line
WPT
: Waypoint
XTD
: Cross Track Distance
XTL
: Cross Track Limit
Activated target
: A target representing the automatic or manual activation of a sleeping
AIS target for the display of additional information
Associated target
: A target simultaneously representing a tracked target and a AIS target
which are decided as the same
Chirp
: A type of transmission waveform with intra-pulse frequency
modulation used by solid-state radars. Its radio wave type is classified
as Q0N.
Clutter
: Unwanted reflections on a radar screen, from sea surface, rain or
snow.
Display
: Screen displayed on the LCD
Frequency deviation range : 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.
Interswitch Unit
: A device to switch over two or more radar display units and two or
more radar antennas
Leg
: Line between two consecutive waypoints
Lost AIS target
: 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.
Lost tracked target
: One for which target information is no longer available due to poor, lost
or obscured signals.
Power amplifier
: A radio frequency amplifier circuit consisting of semiconductor
elements used for solid-state radars. It employs a high frequency, high
power FET.
Primary
: Main positioning sensor
