Section 13 Setting up the Operation Mode 13-10
13.6 Setting Radar Trail Mask
Radar trail mask
If radar trails of unnecessary targets are not drawn on the radar trail of target you want to focus on,
you can leave the radar trail you want to pay attention to. By specifying a target, that radar trail will
be masked and will not be drawn.
The target that can mask the radar trail is up to four tracking targets and the associated AIS
targets. If an unassociated AIS target is specified, acquire the target and mask the radar trail. If a
sleeping AIS target is specified, activate and acquire the target and mask the radar trail.
Memo
The following targets can not be associated, so they are not targeted for the radar trail mask.
• AIS AtoN
• AIS SAR aircraft
• AIS coastal base station
• Initial acquisition target
The area of radar trail mask can be displayed and extended. However, if the mask area is
excessively extended, a radar trail of target passing nearby is not drawn.
Set a radar trail mask function.
