Hi,
I did a couple of tests/calculations the last days about the radar of the Su27...and I really got stuck with something...I hope somebody can help me out here and find my mistake.:helpsmilie:
Here is what I've tested.
I tried the same test at different distances like 20,50,70 away too - So far similar results...I'm still testing.
Here are some HUD pictures I've taken: http://imgur.com/a/JgsFe
Vertical scan:
- I put myself (Su-27) at 5000m, about 650kmh.
- I put 3 contacts ( Su-27) 10km in front of me with same speed an 1000m altitude separation. 1st at 6000m, 2nd contact at 5000m and 3rd 4000m respectively.
- I put my radar on with default expected range 10km and started to scan with 1+,0,-1 elevation. I tried all PRF settings.
At elevation +1 I only see contact 1. I had to dive about 700m to see contact 2 as well on the radar.
At elevation 0 I only see contact 1,2.
At elevation -1 I only see contact 2,3.
So can anyone tell me why I don't see all 3 contacts at elevation 0? Or why I do see contact 3...I should either see all three contacts or only contact 2 at elevation 0. AFAIK my scan zone 10km away from me is about 1750m in total (875m up, 875m down) - If this is right I should only see contact 2 then. Also I shouldn't see contact 2 at elevation -1.
Does anybody know how the radar cone is implemented/calculated in the game? It's a 10° degree beam going 5° up and 5° down from your nose in initial position, right? And manipulating the elevation will change the radar angle in relation to the expected range !?
Horizontal scan:
-Again I put myself (Su27) at 5000m,650kmh
-I put 1 contact (Su27) heading towards me 25km away and 12,5km to my right at same altitude.
If I scan in initial position without manipulating the radar I'll see the contact on the right limit of my HUD. If I increase my separation to him >12,5km he will disappear on my HUD. So why is the limit at 25km away 12,5km? That's not 30°, isn't it?
Thanks for any help! I'll keep testing in the meantime ;)
