Doubt about TA

To see ownship on the TA, the TA must not be in the longitudinal axis of the ship/sub.
If the TA is lower than ownship but in the longitudinal axis of ownship then you won't see ownship.
The only moment you need to be aware that the TA is bending down is during tma, if you go too slow the bearing lines will give a very bad tma, so you must keep a minimum speed to have the TA at the same level than OS to have good bearing lines.

That is not what i want. I don't want to see ownship. I want to see "across" ownship, when the TA is bend down. In other words there shouldn't be any black area on BB when the TA is selected.
When I turn i see ownship noise also in BB, but it is not a very thick line, at least with the Seawolf, so it shouldn't cover other contacts "in front" of me...

This blanking on towed array may be also part of game balancing. Not all in the game tries to be realistic.
Teoretically, there is no need for blanking anything on towed array. Ownship is pretty far from the sensor. Does real subs have it blanked ? Who knows ? Any bubbleheads wanna put some (maybe classified) info here ?

TA through turns is modeled pretty well in BB.

Of course you will see ownship louder than anything else. What you see on BB (in american platforms) is all the noise around you, with areas of greater noise showing up brighter. Just as one merchant can mask another's noise, ownship will mask the noise of anything on the same bearing as it is. This is one reason why tracking on forward endfire is so futile, as well as a damn good reason the sphere doesn't listen 360 degrees.

That's always good to hear

Well .. what about NB ? You would need pretty strong signal to mask other frequencies too. It is true that DW clasification filtering does not work very well with 2 (or more) contacts at the same bearing. It will usualy interpret the lines as something totally unknown. But still you can mark, and with some practice, even classify manualy.

This is also correct. I cannot envision a circumstance where you would gain a NB tonal while the TA was turning though, so it seems a bit moot in this circumstance (or maybe I am misinterpreting).

I mean on narrow band you can see easily thru louder contacts. In DW you just can't hide sub under tanker. Specific lines of the sub will just be there. Is it realistic ? I guess so - well the sub could get really close and it could get masked by buffles, but that would be pretty dangerous anyway.

It is easy to mask broadband noise with louder noise, but it is very hard to find a contact that puts out the exact same tonals as you do.
