6.4.2.3 Vector Length (Vector Time)
The Vector Length of a target is proportional to its speed, and the vector time can be switched in a
range of 1 to 120 minutes.
The following figure shows an example in which the Vector Length is set to 6 min, and the tip of the
vector represents the target's position expected to reach 6 minutes later.
