The change is for that little box that you briefly get when trying to lock a target you spotted on the radar screen by pressing the “Lock Radar/IRST on target” (the radar searches that area of the sky to find and lock itself onto the target).
The change also has nothing to do with TWS, it is just a small typo in the datamine post.
The 2.5° and 2° come from the barHeight parameter, which describes the distance between the bar centers
The 3° comes from the angleHalfSense parameter (usually at the top of the file in the transceivers section), which describes the beam width of the radar
The 10° comes from the width parameter multiplied by 2 (might be wrong on this one, could be just 5°), which describes the length of each bar from the center of the bar (so half of its length)
Lastly, the number of bars comes from the barsCount parameter
AFAIK, almost all radars use box scans that are the height of the tallest scan mode or even higher, because the game does not fully support locking targets on the bars they were detected at, so the lock box is just positioned by azimuth and not elevation. Only some TWS aircraft have shorter lock boxes (F-14B for ex). With those you can’t even trigger the lock box with target cycling off if the radar cursor is not on target.
Ah that’s a shame. Was really hoping they were finally working on the F-15 radar again (well maybe they are and this is the first of many changes to come).
The F-15 A could find fighter targets at about 60 nm, it took a while, at 40 nm the targets were found almost instantly. As players already know, the original APG-63 radar could not attack and track another target at the same time.
With a radar mode called Velocity search, you could find the target at a greater distance, but it was also bad if the pilot forgot to switch the radar to another search mode if the target was closer. I know about the paper assumptions of the APG-63 radar. I’m not refuting or confirming them. But in 1982 the actual range on a fighter target was about 60 nm, at least at Holloman AFB.
Gajin add F-15C MSIP II (1996) from USAF with AN/ALE-56 BOL but currently won’t change countermeasures on F-15A (USAF), F-15A Baz (IAF, IDF) and F-15J (JASDF)
Its not just paper data. APG-66 information is known through
The data discussed were obtained from an extensive
flight test program undertaken during the period from
June 1977 to October 1980 and from follow-up computer
simulation studies.
.
Then we have normalized data(same RCS ) comparing APG-66, 65, 63 radars. For an (~2m^2) sized target the APG-66 detects it at 22 nautical miles, APG-65 at 45 nm and the APG-63(PSP) at 77nautical miles.
From an F-18 pilot who flew in the Tornado ADV with the exchange program
we could get quite long range contacts in the tornado like probably better than most the teenage Fighters other than maybe the F14 or the F15 but certainly better than the 16 or the 18
Now where do you get
But in 1982 the actual range on a fighter target was about 60 nm, at least at Holloman AFB
In no way do I want to argue or refute what is written from other studies. But 60 nm, yes. The targets didn’t light up immediately at that distance setting, but after a few seconds, whereas at 40 nm they went visible almost immediately.
The APG-63 radar was better than the AWG-9 in target tracking capability but had less range. By the time the F-15 pilot community learned how to fool the AWG-9 radar, the Tomcat started having a hard time in BVR.
I am attaching one picture with 90 km, which is 49 nm.
I’m not saying anything, just that reality is complicated.
You know what you are saying its nonsense. If you read that document, which you only skimmed through, there is no classified or any kind of sources quoted for the apg 63 in terms of range. You see several errors regarding radar details in it, look at beamwidth, 3°. Wrong, the BW is 2.5° on the apg 63.
12.9 kW peak power. I might believe it if its for whole radar set to account for cooling power etc but not the waveform.
Its a good document do have an idea of what is done inside and learn the differences with HPRF/MPRF but in no way it gives radar performance details.
Reality is not as simple as just skimming around a google result
And again, you haven’t quoted anything for those figures other than the picture that came up when you lltried to get radar info( we see the highlighted " F-15")
I would suggest to research more about it…
Specifically what I said on last post which is based on guess what? Measures data, document for the DoD by the IDA, and the radar equation
Hey, where did you get the BW value? I have been looking around to find the BW for the larger aircraft (F-15, Su-27), as in the game they are 3° and I believe it should be narrower, but I only found some tangential evidence for the Flanker.
