sonar? what's going on?

[gAiNiAc]

Sonar works fine. Which means barely at all, it gives you a crude tactical picture. Frankly the "lines" are a cheat, but then again you don't have a tracking party.

i think that you have missed the point ! i play sh3 with no map update (witch means that i haven't sonar lines at my navmap ! )
the point is that: when sonarman says for FIRST time 'long range' that means that the target must be exactly at 20km ( unless ....he is ...beaf ! ) ,he also gives us the bearing so we can mark the exact position at the map.

a lot of testing shows me that the sonarman screams long range when he want and not when the target enters the circle with radious 20 km ! thats the broblem (see the hydrophone hunting tutorial by raduz and you will get the picture ....)

privateer: thank you for that information....you think that the sonarman isn't beaf at last?

The range the sonar man gives you is a randomized estimate, it isn't supposed to be exact...........

hello gainiac ,are we talking about the real life or about the game?

The game specifically, but in real life I'm sure that a sonar operator, at the time could not accurately (beyond an aducated guess) estimate the target range without an actual active input.

[makman94]

well,in that case you have to accept that the behaviour of sonarman is ordered by some files.if that files orders sonarman to say 'long range' when the target enters 20km radious circle he has to do so....or is something wrong here (i agree in general lines with you but privateer gave us a good information.if the sensor values are randomized is there a way to set the probability at 100% to alert us when the target enters that circle?)

Well..........What fun would that be? Why should it not be random?

This doesnt make sense. A target running at max or medium speed is earlier spotted then a target at low speed or with idling engine among other factors influence it. Its a passive sensor and relies on the behavior of the target.

If the hydro-operator says "long range" when the target crosses the exact 20km radius it would be a big spoiler and far away from reality. Range based on listening to soundlevel is everything but exact science. Too many variables. I allready have a problem with the hardcapped max range of 34km. If you hear it yourself, you know it is within that. If not, you can be sure nothing is within that range. The max range should extend out beyond the range a screw would be audible.

I disagree though that you would need to be in the hydrophone-shack all the time if you do the listening yourself. Just a quick listen and go about your business again. If you found something just head towards it or lead it some in the direction of the drifting sound. Checking again some 15-30 minutes later for a changing bearing and correct your course.

But if you want to know a bit more about it's motion before sprinting towards it try this:

nirwana : you are absolutely right (nevermind about the reality so much,i don't think that sh3 'reads' all theese parameters)

pisces:yes i can hear it but sonarman is silence (sometimes don't inform me if something get's in sonar's area - circle with radius 34km,i think that this is another broblem that must be solved.i understand that it depends about too many parameters as nirwana said)
i am saying that i must be always at sonar room(to be more exact i mean to order sonarman to give me report) because i want to 'catch' the moment that he will say for first time 'long range' or 'medium range'...(medium range means,at least at my settings, circle with 8km radius)thank you for the link you gave.it seams very interesting and will look at it with attention
thank you all and sorry if sometimes i get monotone...

Hi, interesting discussion, I toke a look in Sensor.dat by using SH3ditor. Following are what about GHG/KDB hydrophones parameters:


GHG
SensorType=Hydrophone
PreciseRange=0
MaxRange=25000 (There are also GHG_9 and GHG_2 at 20000 in the Dat file)
MinHeight=-300
MaxHeight=0,0
MinSensorHeight=-500
MaxSensorHeight=-3
Surface=0,0
RPMDetLevel=0,25
SweepPeriod=30
SweepArc=16
ProbInsideArc=0,95
Revolving=False
SkipSweep=True
Bearing(..)=2/150;210/350

KDB
SensorType=Hydrophone
PreciseRange=0
MaxRange=25000 (There are also a KDBtype9 at 20000 in the Dat file)
MinHeight=-300
MaxHeight=0,0
MinSensorHeight=-500
MaxSensorHeight=-3
Surface=0,0
RPMDetLevel=0,25
SweepPeriod=30
SweepArc=16
ProbInsideArc=0,95
Revolving=True
SkipSweep=True
Bearing(..)=0/160;200/360


This is what i found in CFG files:
;Hydrophone
Hydrophone range factor=1
Hydrophone fog factor=0
Hydrophone light factor=0
Hydrophone waves factor=0.2
Hydrophone speed factor=0.5
Hydrophone enemy speed=0
Hydrophone aspect=0
Hydrophone noise factor=0.4
Hydrophone sensor height factor=0
Hydrophone already tracking modifier=20 ;[detection probability modifier]
Hydrophone decay time=150 ;[>0] already tracking bonus decay, in seconds
Hydrophone uses crew efficiency=true ;[true or false]




We can try to increase MaxRange up to 35000m and let see in the operator can hear a contact at this distance. Or we can modify the ProbInsideArc (the Detection probability inside the sweep arc.). Also note that "hydrophone uses crew efficiency"=true.

hello sag75,i am afraid that i 'll disappoint you because the broblem isn't so simple as it looks .

rubini had tried to do something about that but no more news till today (see that thread: [REL]Visual and Hydrophone detection issue: a new workaround )

i 'll try your suggestion and i 'll informe you if i have had any luck ! (my knowledge at editing files is very low and rubini saying that it is difficult i have to accept it....)

thank you for your time,greetings
