Vector Modes
Vectors are shown on the radar display to indicate the velocity (speed and
direction) of own ship and moving targets. All vectors are shown as a
dashed line beginning at own ship CCRP or the target origin. The length of
the vector indicates speed and its bearing indicates direction.
Vectors are only displayed when the system is in Transmit mode.
Target vectors are drawn using the same colour as the target symbol,
based on the following conditions:
 Target with no alert condition : Non-flashing green
 Target with unacknowledged alert : Flashing red
 Non-dangerous target with
acknowledged alert : Non-flashing green
 Dangerous target with
acknowledged alert : Non-flashing red
For information on own ship vectors, see `Own Ship Symbols’ in Chapter 3,
Basic Operation of Radar.
Selecting the Vector Mode
The vector mode determines whether the vectors represent the true
velocity of targets or the target velocity relative to own ship. The vector
mode is either True (T) or Relative (R) and is aligned with the Trails mode
(relative or true).

True Vectors
All moving targets and own ship
have a vector representing their
movement (speed and direction)
over the water/ground. Stationary
targets do not have a vector.
