Hello all captains,

Maybe anyone will give me a hand,and a piece of advice in such situation.Seawolf's TB-29 port towed array is showing nothing in broadband,but narrowband at 50 Hz tonal is picking out Akula class sub at two different bearings.

How could I distinguish which one of those narrowband towed array bearings is an ambiguous bearing?The task is complicated as I cannot have both 50 Hz lines on display at one time,so I cannot see,which one of them is changing it's bearing,getting darker,or getting different elseway while the Seawolf is completing a turn in order to solve out the ambiguity.

How do you usually deal with such weak towed array contacts when solving out the bearing ambiguity?

Best regards,
Stan.
