The question is reasonable if you don't know much about missile guidance. I don't think Raviar is making any claims but only asking for clarification. IR missiles can't measure distance so it might not be clear how they determine lead. Proportional Navigation relies on line of sight, so range isn't needed. This allows IR missiles to lead their target without a radar or range finder. So it is possible for the mentioned the missiles to fly lead, although if they are completely accurate compared to the real missiles, I don't know myself. 4 Awaiting: DCS F-15C Win 10 i5-9600KF 4.6 GHz 64 GB RAM RTX2080Ti 11GB -- Win 7 64 i5-6600K 3.6 GHz 32 GB RAM GTX970 4GB -- A-10C, F-5E, Su-27, F-15C, F-14B, F-16C missions in User Files Link to comment Share on other sites More sharing options...

I got my answer by @Exorcet Thanks Its literally the same thing. the diagram i showed you is featured on the AIM-9 wiki page . @Exorcetdescribed proportional navigation, and i illustrated it see for yourself: https://en.wikipedia.org/wiki/AIM-9_Sidewinder https://en.wikipedia.org/wiki/Proportional_navigation Edited February 10, 2023 by ngreenaway 1 [sIGPIC][/sIGPIC] DCS: The most expensive free game you'll ever play Modules: All of them System: I9-9900k, ROG Maximus , 32gb ram, RTX2070 Founder's Edition, t16000,hotas, pedals & cougar MFD, HP Reverb 1.2, HTC VIVE Link to comment Share on other sites More sharing options...

I got my answer by @Exorcet Thanks It's relevant to all missiles using proportional navigation; typically that's what a homing missile will use. Radar or IR doesn't matter here. In this case, radar can add information (closure, target vector) to make the homing even more capable, but in both cases the missile will go into a collision course. Even beam-riders and SACLOS missiles can go for collision - you need the right instrumentation to compute intercept and point the missile in the right direction, but there's no need to assume that anything will be doing pure pursuit until you see that it does.
