Radar presentation and video processing
Presentation and visualization options section
In the lower section of the system data area the visualized buttons represent different func-
tions and operations related to the presentation options.
Orientation and motion modes
The function of this line (“System data area sections” on page 23 and “Shortcuts” on page
27), normally labelled with the actual orientation and motion mode status, i.e. “HUP RM RT”,
is to select the Orientation and Motion mode of the PPI. Pressing the Orientation Motion and
Mode Selection button in the system data area, the “Orientation and Motion Mode Menu”
will be visualised. Operating within this menu, the operator can choose between different
combinations, where:
•
“NUP” stands for North Up, “HUP” for Head Up and “CUP” for Course Up.
•
“RM” stands for Relative Motion and “TM” for True Motion;
•
“R Trails” stands for Relative Trails and “T Trails” for True Trails;
The Reset Course button is enabled only if a Course Up is selected. Its function is to reset the
presentation to the actual Course Up, for example during a manoeuvre.
The function of the Auto Presentation Reset Check button is to enable/disable the auto pre-
sentation reset after every range scale change.
Further description of the available presentation modes:
Head Up
Operating in Head Up mode, the Heading line on the
PPI is oriented on the 0° of the bearing scale, and the
radar image is displayed relatively, when own ship
turns the radar image rotates. A short red marker on
the bearing scale represents the north marker, indi-
cating the actual own ship heading related to North.
The target echo is displayed at its measured distance
and in its direction relative to own ship’s heading.
This is the only orientation mode available if the radar
is not connected to a heading source. The Head Up
mode is available only in Relative Motion mode. To
choose True Motion mode or Relative Motion True
Trails mode, the operator needs to select North Up or
Course Up.
