Here's a dupe for those here :

Early_SD v1.1
SensorType = 1
PreciseRange = 12000
MaxRange = 55560
MinHeight = 6
MaxHeight = 2500
MinSensorHeight = 0.2
MaxSensorHeight = 20000
Surface = 100
RPMDetLevel = 0
SweepPeriod = 1
SweepArc = 0
ProbInsideArc = 0.95
Revolving = 0
SkipSweep = 1
BearingMin = 0
BearingMax = 360
ElevationMin = 359
ElevationMax = 90

Early_SD v1.2
SensorType = 1
PreciseRange = 10000
MaxRange = 55560
MinHeight = 100
MaxHeight = 5000
MinSensorHeight = 0.2
MaxSensorHeight = 20000
Surface = 100
RPMDetLevel = 0
SweepPeriod = 1
SweepArc = 0
ProbInsideArc = 0.85
Revolving = 0
SkipSweep = 1
BearingMin = 0
BearingMax = 360
ElevationMin = 359
ElevationMax = 90

Late_SD v1.1
SensorType = 1
PreciseRange = 23000
MaxRange = 111120
MinHeight = 6
MaxHeight = 2500
MinSensorHeight = 0.2
MaxSensorHeight = 20000
Surface = 100
RPMDetLevel = 0
SweepPeriod = 1
SweepArc = 0
ProbInsideArc = 0.95
Revolving = 0
SkipSweep = 1
BearingMin = 0
BearingMax = 360
ElevationMin = 359
ElevationMax = 90

Late_SD v1.2
SensorType = 1
PreciseRange = 23000
MaxRange = 111120
MinHeight = 80
MaxHeight = 5000
MinSensorHeight = 0.2
MaxSensorHeight = 20000
Surface = 100
RPMDetLevel = 0
SweepPeriod = 1
SweepArc = 0
ProbInsideArc = 0.9
Revolving = 0
SkipSweep = 1
BearingMin = 0
BearingMax = 360
ElevationMin = 359
ElevationMax = 90

Note : To compare with SJ v1.2 (max height changed from 200 to 80)

Early_SJ v1.2
SensorType = 1
PreciseRange = 15000
MaxRange = 54864
MinHeight = 0
MaxHeight = 80
MinSensorHeight = 0
MaxSensorHeight = 20000
Surface = 100
RPMDetLevel = 0
SweepPeriod = 20
SweepArc = 9
ProbInsideArc = 0.95
Revolving = 1
SkipSweep = 1
BearingMin = 0
BearingMax = 360
ElevationMin = 357.5
ElevationMax = 30

At this point my thoguht is to back up, rewind, and take things step by step. line by line. Theres some other variables at play here, and id venture a guess that nobody really understand what they are or do. If you do, please say so.



Most notable changes is they made the min/max height alot higher. We also know if you raise the minHeight past 8.3 or so, air contacts cease to be. I have to wonder whats the min/max sensor height do?

The MinSensorHeight and MaxSensorHeights should control the same as for the passive sonar. I changed those to have an affect. They ranges from about -6 to -300 in value. I assume that is -6 meters to -300 meters deep.

But according to that logic, the setting are 0.2 and 20000, the same for both -thus they BOTH should be screwed up! Detecting everything with the bounds of the other parameter MinHeight and MaxHeight. Try changing the Min/Max SensorHeight to something normal and see if that works.

Update:

notice SJ works and its SweepArc is not zero.
SweepArc = 9
ProbInsideArc = 0.95

But for SD SweepArc= 0. Hard to pick something up inside a zero angle sweep arc. Set for 9 like the SJ and see what happens.! set Revolving = 1 also. Duplicate and see if it works. Just a guess if all else fails.

Basically meaning, Min of 359 is pointing 1 degree below the horizon, Max of 90 is straight up. The SJ data has Min/Max of 357.5/30 . Looks fine on papar but it appears it's not using those values for that reason.

Yes, that is because the SD Radar is NOT rotating around the Z-axis. See above, that might would explain it. Z axis is the direction pointing straight up. It needs to turn in a full circle. Sounds good as any theory...:/?

[Jace11]

My SD is picking up all air contacts from all directions..

I know its my SD cause I am using a porpoise without an SJ.

It IS still detecting ships however. Can't prevent that yet.

[Jace11]

My Tests were done as follows...

put this in your library/ussubparts folder:

http://www.speedyshare.com/292155739.html

and extract this test mission and put it in your single missions folder

http://mpgtext.net/subshare/18Edit.zip


then run the mission and use TC for a while..



You start with 4 aircraft approaching from N, S, E, and W plus 1 small and 1 large surface contact from SE and NW respectively.

Pick a 45 porpoise (not SJ - without the campaign upgrade) and see if you spot them all.. I can..

BTW I have not entered any of my own values into the subsensors file, this isn't a tweak, I have merely combined those from 1.1 and 1.2 to get it to work.

[kakemann]

So what you are saying is that you actually got it to work?

[Jungman]

Jace11, try setting MaxSensorHeight and MinSensorHeight = to MinHeight and MaxHeight.

It is the *SensorHeight that controls the enviroment it will be defined in. Limit that should work. They are set for 0.2 and 20000 ; means they should be picking up everything...ships and airplanes. It seems it does.

[Jace11]

Good idea Jungman. At work now, so can't. Maybe someone else can try it.

The MinHeight going from 8.3 to 100 was responsible for breaking SD, therefore, I think the MinHeight refers to the tallness (ie vertical size) of the object NOT the height it operates at. So as no aircraft is over 100m tall, then they are not seen. Maybe the dev team intended to increase the sensor height, but increased the wrong one…

That sound plausible I think, increasing min sensor height on the SD to say 100 should be the fix? And lowering the max sensor height of the SJ should stop that detecting airborne targets??

Wish I could test it, but I have work….

Sweeparc zero !

Mmmh... that may be an error. I will look that, many thanks Jungman.

[TopCat]

That's indeed very strange. I installed jace's sensor-file and testmission. And everything worked exactly as he described.
Then with the same sensor-file I loaded my own testmission, and guess what. The 90 to 270 error with aircrafts (see my post from yesterday) came up again. That's very weird.
I will upload my testmission when I'll be home from work.

Hmm...I thought "SensorHeight" was for the sensor's "altitude" range, i.e. the altitude/depth the sensor must be at to work, while "Height" defines the altitude/depth the target must be at to be detected.

Also, see sonar thread for related discussion and possible transposed values:

Ok... i dont want to claim victory yet, but i think so i discovered the @#$$ problem.

1]
In SH III the sensor anglas was taked :

Zero degree UP
180 degree Down.

2]
MaxHeight and MinHeight goes from up to down, but it is from zero to 180, vertical axis.

3]
But in SH IV SD radar it seem to be :

Zero degree nose
180 degree back

zero to 180 is not the vertical axis here, is the horizontal axis.

4]
Then, if maxHeight and MinHeight goes from zero to 180 axis, it means this value is gong from nose to back....

It is the horizontal axis !

5]
When we adjust MinHeight and MaxHeight, really we are adjusting MaxRange and MinRange... into the horizontal axis !



No... no... i not become crazy... :rotfl:

just adjust into file V1.2, in wich one we lost all radar contacts :

MaxHeight=25000
MinHeight=-25000

and you recover the contacts....

Then.....

If this is true.... im not sure yet.

MaxRange and MinRange works as MaxHeight and MinHeight ????

SD still picking up ship contacts, but i think so it is due the settings , may be all settings are rotated 90 degrees.

When we adjust a value thinkig we do it into the vertical axis, really we are adjusting a value into the longitudinal axis !!!

Please it is abit confuse, good is some body can test.

Not sure if this is the problem, but i recover the contacts and it is the only logical explanation i can reach for this behaviour.

.

[Redwine]

Well here the settings i arrive up to the present time...










Already Done File Here :

http://files.filefront.com/Sensors_s.../fileinfo.html





This settings works over a V1.2 file, if i dont made the mistake to mix files !!

But SD still picking up ship contacts.

It is a step forward, almost we have the file for V1.2 working another time, but still with the same problem than in V1.1.

But give us the chance to use the file for the correct version... !

Sadly SD still catching ship contacts, i am not sure at all of this...

At first, in real life is a SD can pick up a smal plane flying at 30m.... why it cant pick up a masive steel bridge of 65m of a Battleship ?

Did SD in real life avoid a ship eco ?



Interesting....

I attempt to change the value :

MinSensorHeight=0,2

to a value like 100.... and all air contacts lossed.


Up to this present moment, a theory i have, is may be, only may be, the tweak file we are using do not adress the correct settings...

Please, do not ofense Mraah !!! is only a posibility.

The second posibility is the Dev Team put the zero infront, instead up, as in sonars, and do not chage the names for the entries...

May be i am saying stupidity, i need help guys testing these settings and need other opinions

The performance statistics were posted earlier in the thread:

PERFORMANCE
Maximum reliable range.

Target......................................Range in Mile
Land 3,000 feet or higher.............35
Land 1,000 feet..........................20
Large planes above 1,000 feet.......12-20
Small planes above 1,000 feet.......8-15
Low planes.................................Not detected

Due to the fact that low flying planes will usually not be detected, lookouts must
be alert for aircraft flying at low elevations during daylight hours.


Minimum range.
The minimum range on aircraft is about 2,500 to 3,000 yards.

No surface contacts, no land contacts unless the elevation exceeds 1,000 ft. Note the minimum range. I suspect that if surface contacts were detected, it was likely within this minimum range. For the purposes of the game, surface contacts should not be returned by SD radar, especially since SD was range only, no bearing returned.
