I don't understand the sensors

[Mister_M]

Hello,

I'm trying to understand how the AI sensors work.

For example, for the ASDIC, I've set the max range to 2700 meters, and an elite destroyer detects me only at 500 meters, why?

Here the files (there is even a mission to make tests): https://www.mediafire.com/file/ew8fa...nsors.zip/file

Man it was Asdic wasnt Sonar that the reason Because asdic was effective from close range than long range For long range was Passive Sonar but it effective if the ship was not in fast speed because it could be make the Sonar man Cant hears Because of engine + Propeller Noise

ASDIC = Sonar

Well i have the Book That Asdic More Like Active Sonar For close Range And For far Rang Was Passive Sonar Because it will not use Ping Sound but If Active sonar[Asdic] Has ping sound wich mean it work with close Range and passive sonar will deactive if Sonar active was Activated

Yes, there is a confusion nowadays. But in WW2, SONAR was the American name for the device called ASDIC by the British.

"Passive sonar" as you call it was called hydrophone only (IMHO).

Yes ASDIC and Sonar are the same thing.

Regarding your original question: I've worked on the sonar systems quite a nit and currently use an active mod like yours that extends range to 2500 meters (which is pretty historical). The problem you are facing is that AI escorts won't use active sonar until they know a U-Boat is in the area--usually due to a ship being hit by torpedos or a visual/radar contact. That means they rely on passive detection prior to one of those events and that seriously limits their effectiveness as long as you do a silent approach.

Sonar ranges are decreased by several factors--weather, contact aspect and--especially--crew quality. As far as I can determine, the only crews that enjoy full sensor ranges (of any kind) are elites. The other classes seem to drop down the scale by a factor of 20% per quality level. So if you're up against a novice crew, you should not be in any danger at all. Elites also have a disturbing trend in their accuracy and will drop dc's on target all the time (as ir should be IMO). They also know your depth which really wasn'r possible until the introduction of Type 147 (Sword) sonar which, while short ranged, could be aimed like a searchlight. They could point it down as they passed over a submarine and obtain its depth. That wasn't introduced until mid 1943.

The best I've been able to do to get a more challenging contest is exactly what you have done by extending the range. And it does keep me a bit more challenged)

Cheers!
