little details

[Bilge_Rat]

I noticed some neat little details:

1. periscope. I was wondering why my attack scope was always coming up pointing towards the stern, but it turns out the scope will rise depending on where you approach it from in the 3d world. If you go around the attack scope and click on it when you are facing the bow, it will rise facing the bow.

2. sonar. I don't know if this was in sh3/4, but the effectiveness of sonar is matched by your speed. The faster or slower you go, the more the background noise increases or decreases, affecting your ability to hear contacts. The sound you hear is also affected by the aspect of the target. A warship coming towards you, which has its screws masked by the hull of the ship sounds different from a warship moving away from you. I spent sometime at the sonar station trying to get past an escort screen, and it is amazing how much info you can pick up from sound alone if you pay attention.

Indeed I've noticed as well why the periscope would raise usually at around 160 degrees for me (because i was a little to the side of it when clicking it) but as far as sonar goes, I'm noob at that so I wouldn't know, but that's a good finding mate and nice to know of.

Where is the 'baffles' or dead zone at 180 for the sonar?

I don't think German WWII Sonar had baffles in the modern sense. The baffles on a rotating T shaped sonar are on the back edge to deaden noise entering from the back and causing contacts to be picked up on reciprocal bearings (noise picked up on the back edge, leading to a target at say 45 being detected with the sonar pointing at 235). Modern sonar has a fixed bafflle behind the sonar mount, as they are more sensitive and would pick up propeller noise at any angle. I'm fairly sure the Germans didn't have fixed baffles.

You should still be able to hear the propellers at 180 ish though - can you not?

Yes, you can and you are! unless engines are stopped

Yup and thats why when I take to the hydrophone myself I always stop motors completely. In this way I can hear a ship form much further than that sound guy could even dream of.

I think he meant whether you can hear something "in the imaginary baffles", i.e. the aft sector. I don't think the baffles were introduced with the GHG yet. But an interesting question who might have come up with that first?
