 Posted: Fri Apr 14, 2006 8:46 pm Post subject: Some torpedo and sonar questions.... |
 |
|
Again, I am asking this from the perspective of many hours of SC.
In DW, have the issues of the omin-transient and torpedo in the water been fixed?
In other words, if someone launches a torpedo 100 NM away from ownship, will I still get the "Torpedo in the water" warning?
As a related question, was the instantaneous "ping" issue resolved when using active sonar? i.e. If I go active, there is the delay while the sound travels to the target, and then the delay while the sound travels back from the target.
Again, I'm just trying to come up to speed as fast as possible while also reading the manual.
Thanks! |

I believe the TIW warning is based on a very sensitive version of your sensors - as if he suddenly made some very loud sound, and if you could hear it (with "enhanced" sensors, the effect on the sonar displays are usually negligible), you get a TIW warning. If you're in a shadow zone (on the other side of the layer) you don't hear anything, so you won't get the TIW until you can. Which is usually after its closer - or you go to the other side of the layer.
The instant ping intercept has been fixed, but introducing a new issue of its own - you now don't hear a second ping emitted before the first reaches you. |

Thanks for the info.
This sounds promising. So it sound like it is theoretically possible to use the layer to mask the launch transients and swim a slow torp below the layer until it get closer to it target. Then pop it above the layer and accelerate.
Regarding active SONAR, Iif I understand youcorrectly, when active you can't emit a second ping until the first one has been returned to you? |

Platform A pings.
In n seconds, B gets it on active intercept.
In 2n seconds, A gets the return on screen.
Platform A pings one time(pa).
m seconds: (m<n) A pings again (pb); interrupting the display drawing; he gets no return on the target.
n seconds: B gets pa on active intercept
m seconds: B doesn't get pb on active intercept
m+n: A gets the return from PB on the targets position.
Did that do it?
If you interrupt your pinging, you stop drawing it, and it can still be heard all the way out, but if you ping in between it doesn't get detected by the sub - is at least the way I understood it. There's no way to exploit this for cheating though. |

Yep, other platforms cannot receive two pings in the water at the same time, but then again, you can only get information from one of them anyway, so there is no cheat. |

TIW calls are still way too sensitive overall. Most modern torpedoes are not loud at all, in fact some are essentially silent. Some do remain pretty loud, but I think the game is using the same loud transient for all torps. |

Thanks for all of the helpful replies.
Thinking about this has brought up another question in regards to DW SONAR modeling.
So say we have three entities in play. A 688i, an Akula and an FFG.
If the FFG pings (for some reason) the Akula, can the 688i (assuming it is in a proper position to do so) pick up the return off the Akula and use it to improve its own firing solution?
Or is this just Hollywood type thinking.... |

The short answer is, no. :know: |

Ooooh... multistatics...
So far I haven't seen a single naval sim on the market do multistatic sonar. I can't figure out why. |

It's not an unreasonable question to ask. Multistatic sonars of several types do exist today. |
