For “Air-to-Air Radar Modes for the CP-140 Maritime Patrol Aircraft”, the number is not wrong, but the units are wrong. They used kilometers when they should have used miles, this is why we had the problem.
In the paper, it mentions that the F-4 size target has a 90 km detecting range. However, assuming this is a mile and converting to kilometers, it becomes 144km. (90*1.609=144.841)
This is completely consistent with the graph in the “F-15 AN/APG-63 Radar Case Study Report”.
This graph shows a detecting range of nearly 80 nautical miles.
But, this does not match the graph in the “F-15 Design and Approach Presentation”, so there may be some confusion about this. In that graph, we see that the T-33 is almost always detected at 65 nautical miles.
However, in the “F-15 AN/APG-63 Radar Case Study Report”, they mention a 20% increase in detecting range due to the upgrade of AMP module.
For a 20% increase from 65 nautical miles, it is 78 nautical miles, which is also matched by the graph in the “F-15 AN/APG-63 Radar Case Study Report”.
Notes: “F-15 AN/APG-63 Radar Case Study Report” was written in 1983 and “F-15 Design and Approach Presentation” was written before that, so this is not conflicting.
Therefore, converting 78 nautical miles to kilometers gives 144 km. (78*1.852=144.456) This number matches the range in the paper if we assume the range in the paper is in miles.
Nice to see. But why their insistence on using that document? There’s no reference to that information anywhere and

What will be the RCS figure used because the F4’s RCS is larger than the T-38 (1.3m^2) and T-33(2m^2)? And the “Medium Target” in the case study is 2m^2.
Even the beamwidth mentioned is wrong. 3° to 2.5° as specified in the -34 and close to the value you get by using optical waves, 42 linear elements at half-wavelength
But principle shouldnt be different because Sparrows requires hard lock, so unless V3 can hard lock multiple targets simultaneously it shouldnt be possible.
Then again why would you use Sparrows with V3? By the time V3 gets added we will probably recieve Aim-120C-7’s.
Technically even the 63v1/ APG-70 has a dual lock mode, which allows for guidance of 2 sparrows at 2 targets at once. Unreliable and basically never used but possible. With AESA it is more than possible as you have multiple beams which can be focused in different directions. Unnecessary since you won’t be carrying SARHs, but possible.
F15s tested proper HMDs in the between 1986-1987. I knew HMS were tested during aimval/aceval but never proper HMDs.
And it was lighter(2.6 lbs) than the HGU-55P at 3.2 pounds.
Spoiler
Vertical Scan, Boresight and Supersearch were removed in favor of HMD Supersearch and HMD Boresight. It also removed the slaving between the radar and AIM9 seeker when in use, so you could fire an aim9 while the sparrow was doing its job on something else.

These were the results during 4 weeks, more kills and better exchange ratio

They actually do train Free For All lmao
The perfect recipe for a disaster but never happens
They also train 2v8s OCA and DCA. Shows how dire the situations they trained for. Outnumbered against waves of enemy fighters. Truly shows their skills and intensity they expected on western central europe.
This was in a simulator unfortunately if I recall correctly. MACS is the name of a simulator setup, though it doe show just how early they were put into testing
