Great, but the F-35 and F3R use AESA radars.
That simulation is rudimentary at best. If it was so easy to deduce RCS values from creating a blender model and running simulations on it, companies wouldn't spend billions of dollars creating these very complex designs. The Rafale might not be a stealth design, read my post I didn't say that, but it incorporates a lot of features to reduce it's RCS.
Clearly you have no understanding of this topic if you think that it works exactly the same across various EW suites spanning from the 80-2000's, what we see in DCS is very simplistic not realistic.
