Testing some aspects of DW (lots of pictures)
 

Hello... once again i have for some while two computers at my disposal, so i decided to try some things in DW on my "LAN" :) Mainly regarding...detection. I did it to see how things work and while i was on it i also took pictures of my testing so you can see it too! :ping:

It might not be all 100% accurate, because DW is really very complex, and thus its hard to accuratelly test al lthe ascpects, but it should give the general idea :yep:

This time it was MH60 versus Chinese Kilo Improved... the helicopter trying to find the submarine at different depths, speeds and other circumstances, using different sensors... so, lets start!!! :arrgh!:

------------------------------------------------------------------------
First test was Kilo detectability againts radar. Kilo was visible on radar when at 14-15 meters, diving to 15-16 meters resulted in kilo being undetectable on the radar. Raising any masts while being at 15-16 meters depth had no effect on its detctability by radar. Getting very close to the kilo did not detected the masts too.
------------------------------------------------------------------------

And now kilo versus sonar :x

This was the lookout on the beginning

The kilo is about 3,5 miles from our helo, running at 5 knots at 15 meters depth. There are two DICASS buoys next to the helo, one DEEP and one SHALLOW. Both ACTIVE - The DEEP one was able to see the kilo pretty well, while the SHALLOW one was unable to see it at all. The layer was at a 230 meters so it seems a bit strange to me. It was surface duct.

---------------------------------------------------------------------------

Then i tried passive detection, and diesel noise :)

Ok, on those two pictures of passive DICASS and passive dipping sonar, you can see, that you can not see the Kilo at 3,5 miles range, 5 knots at 15 meters depth. :P

------------------------------------------------------------------------------

Ok, that was somewhat expected....but lets see what happens if the kilo engages one of its diesels :hmm:

Now we can see you, boy :ping:

------------------------------------------------------------------------------

So what now, will engaging of the 2nd diesel have any more effect???? :stare:

Wow! it definitely does! A big time! :huh:

-----------------------------------------------------------------------------

Now lets disengage diesels, dive the ship to 100 meters and start running at 15 knots!

This tells us a bit about difference in active return in relation to distance to the sub.

So lets go passive now...the kilo, even at 15 knots, is one sneaky bastard! :damn: So the range at which VLAD got hot was measly 850 yards :88)

http://web.quick.cz/zerogreat/Kilo15kts100mRNG1.jpg


But still at this range, buoys get no reading and no frequency alert :cry:

http://web.quick.cz/zerogreat/Kilo15...mRNG1Buoys.jpg


But the dipping sonar hears something! But well...it is a very very faint line, i would probably not notice it not knowing where the sub is :roll:

So....let it come just a bit closer!

http://web.quick.cz/zerogreat/Kilo15kts100mRNG2Act.jpg

At a distance of about 350 yards, plus about 200 yards (because my helo drifted in wind) from the buoys, i have at last got a frequency alert and my deep VLAD and only my deep VLAD showed me a nice faint line.

http://web.quick.cz/zerogreat/Kilo15...mRNG2Buoys.jpg

In the next few seconds the deep VLAD developed a second faint line, but that was the best it done, when the kilo came too close to the buoy, the contact was lost. :nope:

------------------------------------------------------------------------------

And now active detection in relation to depth!

Kilo at 150 meters...

At 200 meters......
http://web.quick.cz/zerogreat/kilo200m.jpg

At 200 and 50 meters...............
http://web.quick.cz/zerogreat/Kilo250m.jpg

Now at 300 meters, there appeared some strange ghost contact! :o Took two pictures of it!

And at 350 meters, the kilo imploded :lol:

Now that is all.... interesting? :hmm: :rock:

Err, you don't think the pictures can be shrunk to quarter size and still be visible?

Hey, that was a great post ZeroGreat! Thanks for taking the time to do the experiment and posting the illustrated results! I think if DW came with a strategy guide that used examples such as yours, the game would be much easier to learn.

Well Done! :up:


BTW: As an aside, I have discovered that a lot of people approach DW like I did, that is, they would love to get the game, but the learning curve scares the heck out of them.

Aye Zero reduce the quality of the jpegs and that would help.

Very good though.

what version of DW and what mods if any?

Of course the pictures can be shrunk...but there is a question... why? :) Umm, because it is a sonar screen, i think it is good to make it as much readable as possible to not loose details :) But if you want, i will see what can be done ;)


Oh, the version, i definitely wanted to notice that but then i forgot :lol: It is the 1.03beta with sound vs. speed fix (maybe it is integrated in the beta anyway? :) ) and font mod :lol:


I also had pictures of the SSP, both from the kilo and from the helicopter, but somehow, both of these pics became lost :ping:

I have problems downloading the pics, even as I have 5000 kbps download speed :doh:

Might be because i was uploading the new versions right now :hmm:

Ok, reduced the overall size from 2,62 MB to 1,82 MB ... should take 3 seconds to load them all on your 5000 kbps line :|\ ... but i dont think 'my' server is that fast anyway :lol:

Thing is Zero I post 1024x768 res pics and they come up quicker.

REduce the jpeg quality when you resave.

When I attempted to save them, they were bitmaps.

That was my first impression when I opened the thread.

If that is the case then no wonder they are taking a long time to load.

Verdammt..... They are JPEGs with 30% compression, i am not that dumb to post uncompressed bitmaps, that would have like 2 MB for EACH picture :huh:

Anyway, thanks to WargamerScott for appreciating my work and not just complaining like others :cry:

I appreciate the work but for some reason they are loading really slow.

Sorry Zero what you have done is great.

30 minutes, still loading... :zzz:

Next time use Imageshack, please!!! ;)

I'm sorry i dont know why they load so slow for you, the site works fine for me :-?

Zero...I wasn't trying to be mean...just letting you know that even with 1.5mb/s download, it's taking quite a bit of time.
