[CHECKING] AA radar is able to track HARM.
nighthawk2174 replied to Martin2487's topic in Bugs and Problems
9L I do wonder if it's because the RCS of missiles is too big. For example this is an ANSYS run on the RCS of the AGM-86 someone did. As you can see frontally the RCS is very small right around the 0.001m^2 mark. In DCS the HARM is something like 0.015m^2 which is much bigger than even the AGM-86 results. Of course one also has to wonder if the AN/APG-73 in game is over performing as well. Imo it's most likely a symptom of both. -
Ok done some testing of note the bug is still there, while I haven't tested closely packed contacts I did go ahead and see how one could generate false contacts if you sere a singleton. Now with a friend flying the 14 and me in an F15 we did a bit of testing. Below are the tacview and track, the test of interest is the last one starting at 20min. Every time the F14 fires his gun there is a false track on his screen. Starting at 21:40 I started a constant 5g turn. Well as you can see from the track every time I pass through the notch (I don't stay in it) a false contact is spawned often heading the opposite direction while i'm still being tracked. This always happened by passing through the notch and not staying in it. This seems odd as the time spent in the notch is minimal and should be well within the coast time of the radar. https://www.dropbox.com/s/acogbv7fy1exnu0/F14_GhostContactsTest1.acmi?dl=0 https://www.dropbox.com/s/gpugdgja65bskub/F14_GhostContactsTest1.trk?dl=0

Yeah I don't have much on its effectiveness just tidbits here and there from different papers and textbooks:
-
With Fox1's wouldn't it be more the case that so long as the main radar is locked onto the target (and stays that way) the missile will perceive the target to grow in apparent size dragging the aim point behind the target? With ofc this being dependent on aspect, range, Doppler gate size, and if the missiles has filters specifically to reduce the s/n (if that's the correct term) from chaff.
-
Np thanks for the repost
-
Fair enough pulse is a very different beast which the F15 also has as well
-
Ehh i'm not so sure about the effectiveness of chaff against modern PD radars, especially the 7M/MH, 120B, and C5.
-
Well I know that most modern jets when in look up will reduce the the size of the doppler gate. In one of the F16 manuals I have I think it said it can remove almost all of the doppler filters when in look up. I know the MIG29 is similar in look down its ~113kts for the blind zone, in look up at long range its ~80kts, and at close range (20-15km) to less than 27 if in look up and the target is close. Which actually makes me wonder does the new radar model take into account different notch sizes if in look up or look down @chizh?
-
Yeah the jacknife at notch, although i've noticed it may not even be in the notch:https://forums.eagle.ru/showthread.php?t=266811 , is a really bad bug and it only seems to have gotten worse lately with all the lag in mp in particular.

DCS - Nhawk's Weapons mod
nighthawk2174 replied to nighthawk2174's topic in Utility/Program Mods for DCS World
Sweet good deal have fun with the mod then! -
I've noticed the false contact bug a bit less but it seems the recent instability of servers has made it worse again? I'll post an update latter after some testing in SP and MP.
-
Wait as far as I could tell they should be right do you have proof of this?
-
Hold on if there is ground clutter that would really just limit the max detection range no? How would it make tracking beyond this more unreliable? Its a PD seeker after all. The introduction of everything I mentioned above yes would make the missile better but its also realistic to what the missile should have.
-
?????? it isn't even that high off borsight of a shot I don't even get your point here. - 7min 30sec
-
On that note are we going to get optimal control, kalman filters, and range gating as well?
-
In game the CIWS systems of both the USN and Russian navy are set to 3 seconds for their reaction time to threats . This seems very high not only for a system that has the ability to plan which targets its going to engage then enagage them right as they get to max range but also a system as automated as CIWS. There are plenty of videos out there of CIWS going from search to tracking a target in well under a second. Same with the RAM missiles which should have the same capability yet unlike gun based CIWS or the command guided SA19 for the Russians have the ability to quickly engage targets one after another. Engaging one then moving on to more targets returning to the inital target only if the missiles miss.
-
In the game there is an action where a unit will hold then a dropdown menu to select a template. Which the group should 'deploy' to. Yet this is not working, I really want to use this to have mobile sam sites that will move around and deploy but it hasn't worked on any unit i've tried it with. With template the group of units is an exact match of or too other templates as well.

Agreed especially with the A10CII on the way.

DCS - Nhawk's Weapons mod
nighthawk2174 replied to nighthawk2174's topic in Utility/Program Mods for DCS World
Hmmm odd as I can select both the SC and Jeff and fly them. I'm going to just push what I have as a clean push and lets see if that works. -
Isn't it the case that the drag above 40,000' is way off?
-
Wait but why ignore Deka on this they said their very confident on their number while your 80sec is purely an assumption... Also good to see my CFD is quite close to yours well within what I'd consider a good margin of error for different solvers with different 3d models.

nighthawk2174 replied to nighthawk2174's topic in Utility/Program Mods for DCS World
Odd as its working for me and everyone else i've asked so far, could it be some other mod or just the mission itself? (also you have the latest hotfix correct?)
