sleeping target it is not associated.
In addition, [CHG SELECTED TGT] and [SETTING] are provided.
[ASSOCIATION] changes priority of the association of all targets while [CHG SELECTED TGT]
changes priority of the association for selected target only.
[SETTING] designates conditional items of association among RNG, CRS, SPD, SPD LIM, TIME
REPRIEVE and RATIO.
RNG: It designates the range to determine association. (0.001NM to 1.000NM)
CRS: It designates the course to determine association. (10.0
°
to 60.0
°
)
SPD: It designates the speed difference to determine association. (1.0kn to 20.0kn)
SPD LIM: It designates the minimum speed to determine association. (1.0kn to 10.0kn)
TIME REPRIEVE: It designates the time to determine association. (1sec to 99sec)
RATIO: It designates the ratio to determine association. (0 to100)
