Sonar New Look
 

I found this photo (public domain) of the sonar station on an Arleigh Burke and I wonder how these things may work? It's far different from familiar waterfalls and they look nice and spatially intuitinal... I mean, the reason for which I sticked with the Akula throughout Sub Command.

Unless they are active sonar displays? The pic was marked as "surface anti-submarine sonar" and it seems that they have narrowband displays below so I don't think so.

It actually can be combination of active (in the yellow frame) and passive broadband (on the border).

The lower screen is narrowband for sure. I mean the upper half. But the lower half ? Looks like intensity/time returns from active sonar, I've seen such graphs in books.

Nice find !

Sorry for digging up an old thread, but I felt that this fits in nicely here.

I found this clip on Youtube, showing a sonar station on a US boomer, USS Michigan (?). I figure that the left console has broadband waterfall displays. The right console, at least the lower display, is narrowband, right? What might the upper display show?

The waterfall display seems to show the same data repeated four times across. Why would that be?

Youtube clip

welcome back!
 

Very cool clip, by the way. I think I'm going to purchase that documentary based on the link in the description.

Anyway, my first thought would be it's the same signal with different kinds of post processing applied to the signal. Remember, Dangerous Waters and Sub Command are simplifications of all these stations. I'm sure the Navy can do at least 100x the stuff with the signal than we can do in the game.

Here's another one showing what I assume is some form of narrowband sonar display, this time on an ASW S-3. (At 18.55 in the clip.)

Since we're doing old school ASW films, just found this:

Great stuff
 

Had a good look through all the videos. Really enjoyed them many thanks!
