How is RCS modeled in BMS?
-
Are those aircraft with RCS reduction measure such as f-22 and f-18e/f more difficult to find on radar? Is superhornet much harder to detect than legacy f-18s in game? Since a lot of these RCS infor is classified, wonder how BMS tackles with this issue?
-
Is difficult, we have to manage between different source, and there are never one single source. Each info can tel something different because it depend of a lot of factor.
I personally change some RCS for the current 4.33 according to some interesting source, I think is well better than 4.32, particulary for mig-29 (a little bit smaller), SU27 (waaayyy bigger) and Mig21 (way bigger too, the small target size in the past Falcon version was stupid). -
Well, The longer, edgy inlets of the F-18 E/F should contribute to a much closer range at which NCTR is possible. The radar can’t look as easy for the fan blades, on which NCTR is based. The angle at which it would work should also be a bit smaller.

Cockpit layout, avionics, FM, whatnot. So the only in game difference between the two is their RCS, right?

And fuel capacity, loadout, IIRC radar performance as well, need to check…

Aha, I forgot about those.
-
I didn’t do the superhornet RCS I think.
-
-
I left it at the same value than before, so if before it was based on the F/A-18C, then yes.
I have no information about this aircraft, then I prefers to not touch it. -
Does RCS increase with external stores ?
Is the RCS value in the editor expressed in m² ?

Yes, but we usually talk about base RCS. Otherwise it’s hard to compare.

Yes, I know, my question was concerning BMS !

No RCS increase with external stores. Some ideas, like linking it to the drag index, but nothing coded yet. Similarly, no RCS changes with aspect angle.
The RCS value in BMS is actually a detection range factor compared to an F-16. Ex : a BMS RCS of 1.5 means you will detect the AC at 1.5 times the range you detect an F-16.
Hence the following formula to convert real RCS of aircraft XXX to BMS RCS :
RCS_BMS_XXX = (RCS_REAL_XXX/RCS_REAL_F16)^(1/4)
-
No, it does not, as far as I noticed.
It would be nice though….imagine RCS depending on azimuth, wavelength of the radar emission, etc. We would need an extra GPU to calculate that.EDIT: Crusader was faster.

Interesting. I didn’t know there is no aspect effect. What about doppler effect? In DCS, sometimes you can break AIM120 lock by going low and perpendicular to the missile. But in bms, it seems AIM120 can always get you. That’s why high altitude lofting tactic so effective in bms. But at the same time, radar on 120 is different from aircraft FCR. CW radar may be better at combating ground cluter than pulse radar.
-
yep, beam work. But agains’t a AIM-120 this is stupid.
-
Doppler notch effect is simulated in Falcon since SP3, but AF did not.

I kinda feel like its a little hard to successfully notch in BMS. Not sure whether that speaks to a lack of skill on my part, poor modelling of radar mechanics on BMS’ part, or excellent design work on Raytheon’s part.
@pandacat:Why 120 so immune to beaming?
Its actually a different type of radar to the fighter, and its design makes it pretty resistant to beaming. If its close enough, anyway. It uses a monopulse radar instead of a pulse doppler radar. Its smaller than the fighter radar though, so its short ranged for a radar, and unless you are coming head on its range is shorter again.

…if I understand the way sims work, I’m not sure any of this stuff is particularly “modeled” at all…other than by probability. Just roll with it, folks.
