A completely different active sonar question

[Palindromeria]

In several novels I've read , the sub skipper refers to the enemies use of active sonar (lets call it a dd for simplicity) as painting a picture of the entire area for the sub, in addition to giving away the dd's pos

in other words

the active sonar (presumably omnidirectional)
from the nasty dd allowed our hero sub
to detect 2 nasty subs that were otherwise silent.

i am assuming this is realistic, simply because it makes sense.
if so,

is this at all do-able in dw ?

thoughts ?

[Palindromeria]

no thoughts ?

k - i am sure 1 of the novels that describes this was SSN by clancy, in which cheyenne effectively renders the chinese navy useless.


i think i also came across it in one of Patrick Robinsons books, but dont recall which.

I am sure it was NOT "Slider"

I think you should see pings and returns on BB. I think half-active can't give you range, only direction.

I'm quite sure in DW you can't do this. You only see pings in active display, and only yours.

this kinda makes sense to me as well.

i am fairly certain that clancy describes cheyenne pinpointing range and bearing
of enemy subs as result of the dd pings though.

maybe the range is a result of triangulation from the
source bearing to return echo bearing ?

k - so its not at all do-able in dw.

still, any more insight would be interesting to learn about.

thanks,

If you know the position of the dd, it should be possible.

Sound does not move two-dimensionally. We pretend that it does so that TMA becomes do-able. When you get into active sonar, it is one of the worst-modeled parts of the game for that very reason. Take active in DW with a LARGE grain of salt.
