When will we get the radar fixed?

[Watari]

you are right. in SP (!!)

 

Lots of the described issue im suffer in MP. Also not always. When im on a pvp server and i get a new plane the radar works mostly very well. After some time of searching, i have the feeling(!), its neary inop.

And thats not only me!! We discuss this often on the mig pvp server and a lot of people mention this.

And dont come with small target blabla. sometime targets fly straight in front and higher of me and you see nothing.

Frederf,

 

It's your second image. These are antena's stabilization limits: +/-70deg roll, pitch +8, -25deg.

 

Are you really sure? It is surprising because in the second image the airplane is pitched down -25 but can still scan +17 above horizon. It is looking 42 degrees above! Maybe it is the antenna which can pitch down -25 when the airplane is pointed up +25? I know I am asking the same question a second time, but it just because I find it incredible.

 

I notice two things about the antenna pattern: First is the scan zone box is outside the antenna path which makes more sense than the Czech PDF. Second the pattern is different. In yours the pattern is simple bottom to top but the other was to do odd lines going up and even lines going down (shifted to be in the middle of the odd lines' pattern). Also there is a difference of 9 and 10 lines total.

 

In the normal and low altitude pictures there is "Psi-OH" in both. Are these angles equal in both pictures? In low altitude the raising of the search area is Psi' which should be 3.5°. If this is held at -25° airplane pitch then radar is looking up 45.5°!

 

Is there more to this manual or book? Is it stated what are the values for the symbols:

Psi-OA

Psi-CA

Psi-OH

Psi-CH

Psi'

Psi-OA Dop

 

I am still curious if the elevation zone figures are for limits of antenna or for detection area. If the detection zone is +17-1.5 then of course the antenna is inside this. 18.5 area subtract 4 for top and bottom beam spillover and divide by 5 bars you get 2.9° which is very close to stated 3° beam width.

[Spectrum Legacy]

Given the +17/-1.5 scan zone do you think the pitch limits are +25/-8 or +8/-25? In order words is the pitch limit what the airplane can do or what the radar antenna can do? I drew both situations. The sum of antenna angles 8+1.5° and 25+17° (or 8+17 and 25+1.5 is the same) is what is required to complete the scan inside pitch limits given. This is 51.5°. For one picture this requirement is distributed +42° -9.5° and for the other picture is +25° -26.5°.

 

Also "3 seconds" is the repeat scan in the auto tracking mode? Is it given an estimate to complete a scan in the overview mode?

 

+-17°40'' is a total of 35°20''. This is nearly equal to 25+8=33° which is apparently the total freedom of scan zone positioning in the vertical. There is a small difference which should have an explanation.

 

Beam width is said to be 3°. If the antenna lateral movement is +-28° then 2° are being detected outside of the limit of axis pointing. Is the same true for the vertical? In an extreme case when the bottom "bar" of scanning is happening at -1.5° then are targets being detected as low as -3.5°? At the top bar when the axis is pointed 17° high are targets detected as high as 19°? The bar scanning diagram isn't so precise to differentiate between dish axis direction and detection angular limits.

 

I admit it was hasty to say the scan zone is symmetrical but it is so confusing why the RP-21 was 24° full height scan with its center tilted down 1.5, 3.0, or 4.5 degrees below the nose. The previous radar was looking nominally 12 degrees below the horizon when employed at high altitude. It had an inferior range of course. It's an exceptional reduction in ability for RP-22 to look so weakly downward that is not satisfactorily explained.

 

That's where the ambiguity in the pdf comes from. It is not stated clearly, where I could say with certainty it is either of those two cases. I got the impression that the whole table is regarding the movement of antenna and its limits. If the author or translator instead mixed in plane attitude of pitch and roll, it would be confusing, but it could of happened (especially because of usage of those two words 'zdvih' and 'pad', where the former is more appropriate for the antenna, while latter would be more suitable for the plane). I'm more inclined to the symmetrical operation, as the antenna in tracking/locked mode can follow the target 30° either way from the centre. But again, it's just my interpretation and the pdf itself is far from being detailed - so I don't know exact scan pattern, or the overlap zones, or whether the beam width is taken into account where those limits and angles are stated.

 

3sec repeating scan time is in search mode. Basically it takes 3sec to get the updated picture on the screen. In target tracking/lock mode, I reckon it is much higher frequency because the beam is focused and as stated, it can endure 10chaff charges per 100m of distance travelled by the target.

Hello, I would want to have if the radar always has bugs yes or no ?

Thx

What is the question?

 

Can you ask again in french?

[zaelu]

He wants to be sure if radar still has bugs or not... confirmed ones.

 

terence44 best way to check is to look here:

If you see a radar bug as solved then you need to wait if it was applied with a patch. Unfortunately Cobra is sick again and can't post last change log. I saw some modifications were made to MIG21 last patch but I was dumb/tired enough to close the "FolderSpy" application without saving the log. How ever, if some changes are made within dll files... we can only assume what it was... not know for sure.

Inverted radar bug is fixed. There are fixes in 1.5.4U3, but not for the Radar.

Yes, I am really sure. :) It says angle of aircraft not antenna and follows how this pitch range is used to show "above", "under" targets in reference to a/c nose angle.

 

In the normal and low altitude pictures there is "Psi-OH" in both. Are these angles equal in both pictures?

 

There is no direct explaination given for the symbols, unfortunately. It says further in text that with activating low altitude switch, limits the lower zone to 1,5 - 2degrees above horizon. So no, from this text, one can conclude that FOV shrinks in vertical.

 

Zones are defined in text as in search mode to be 60deg azimuth, 20deg elevation. However when it talks in detail, it mentions +17 and -1.5 elevation regarding the horizon.

Thanks Cobra. Can you shine some light on what was going on, for those of us that are keen to learn more about the internal workings of the plane, the code, etc? Is there maybe a raycasting function that only looks to the bottom of the aircraft to help determine whether ground clutter drowns out the target reflection?

Are you posting that CL anytime soon?

I'm very curious as well. Was this bug affecting anything related to ground clutter? Did fixing being able to flip the plane upside down for more radar coverage change how radar detection normally works for better/worse?

And another question: Will this update be this coming friday or will it be the one after? I ask this since the Alpha got an update finally.

 

If we have to wait 2 weeks, would it be possible to get a hotfix in the interim?
