SchumiF399 Posted December 28, 2022 Posted December 28, 2022 Hello guys, I've been having really weird behavior with my amraams going dumb as soon as they are going to hit a target. I don't expect a 100% kill ratio every time I fire one but lately after the latest open beta mini patch I am lucky if 2 out of the 6 amraams I am carrying hit their mark. Below are 2 short videos of what keeps happening to me. The 2nd one is a tacview replay. Sorry in advance for recording on my phone. Triple monitors do not play well with recording software.
Default774 Posted December 28, 2022 Posted December 28, 2022 This is due to the target jamming. I've replicated your shots the best I can from two short videos. Cant replicate the mach3 miss, might be due to the target stopping jamming but its impossible to know from your clips. 120hj1.acmi 120hj2.acmi 120hj3.acmi 120hj1.trk 120hj2.trk 120hj3.trk 1

I've noticed that when a hostile is jamming and I acquire a lock I don't get range info until I burn through it. The missiles were tracking fine at first. Is it as intended or is it borked? Thank you for your help!

Thank you for your help! Currently the 120s always enter HOJ mode if the target is jamming regardless of if your ownship radar has burnt through the targets jammer (as far as I know). Currently it seems the 120 either doesn't try to use its own seeker on jamming targets or doesn't ever burn through. In effect this means that if you're engaging jamming targets your missiles are always hilariously crippled guidance wise. How intentional this behaviour is I don't really know. The HOJ logic itself seems very flawed but to what extent certain missed shots are correct you really don't know until maestro responds to your tracks . 3
Default774 Posted December 28, 2022 Posted December 28, 2022 (edited) Slightly off topic, but related to my earlier comment on HOJ. Short track showing a BVR launch on a jamming target. I burn through the jammer at around ~28nm. The missile has valid ranging information, yet it doesn't loft. Does the 120 always fall back to HOJ guidance no matter if there is datalink updates with valid ranging? Also shows a 120 being lofted manually. The missile behaves very strangely off the rails, initially pitching down then back up to slightly less pitch than it was initially fired at. https://streamable.com/28vu7u Is it not reasonable to assume that the missile that the missile would guide normally in the midcourse stage until it goes active if the range of the target is known, then move to HOJ guidance as soon as the missile is supposed to go active, or is the 120 not supposed to behave this way? 120hb1.trk 120hb1.acmi Edited December 28, 2022 by Default774

Default774 Posted December 28, 2022 Posted December 28, 2022 The same weird off the rail behaviour occurs with the 120hf1-3 tracks after taking another look. Missile fired with the ASC centred (plane doesn't adjust ASC/ASEC for jamming targets?) performs a weird manoeuvre off the rails. https://streamable.com/cmde4n
Mad_Shell Posted December 28, 2022 Posted December 28, 2022 (edited) The whole jamming environment needs an overhaul in DCS. Burnthrough range is always the same for all aircraft and radars, no matter target RCS, radar power, jammer and radar technology... the AMRAAM never lofts even if the target in within burnthrough range, the AMRAAM seems to remain in hoj mode without trying to get a radar lock (or has no burnthrough range modelled)...

SchumiF399 Posted December 31, 2022 Author Posted December 31, 2022 Here is a tacview file of an engagement between myself and another random person on a different server(Blown Head Gasket F16[me] and a Mig-29 [Boofly]). I am extremely new to tacview so please bear with me. This guy was jamming and all three missiles go dumb. The last missile was below a mile so I didn't really expect that one to hit.
