6    Speed 
 
Set a speed difference between a tracked target and an AIS target to be identified as one 
target.    Set the speed range between 0 and 99 kn. 
 
A smaller speed range means a stricter condition. 
The possibility of mistakenly identify resembling targets will be lower, but targets are less 
likely to be identified as one target. 
 
A larger speed range means a looser condition. 
Targets are likely to be identified as one target, but targets with similar parameters are 
likely to be mistakenly identified. 
 
Adjust the setting in accordance with the intention.
