D4n Posted March 15, 2020 Posted March 15, 2020 Latest OpenBeta. As can be seen in the attached Tacview-files (+attached a trackfile + .miz file of AIM-120B working as intended), while the AIM-120B behaves realistic (seeker losing target due to big chaff radar returns when target is obscured by chaff), JF-17's SD-10 in 3/3 times (easily reproducible in singleplayer) totally seems to ignore target-obscuring chaff clouds and keeps tracking+hitting target anyways.Tacview.zip120B-realisticChaffBehaviour.trk120B-realisticChaffBehaviour.miz DCS Wishlist: 2K11 Krug SA-4 Ganef SAM, VR-TrackIR icons next to player names in score-chart PvP: 100+ manual player-kills with Stingers on a well known dynamic campaign server - 100+ VTOL FARP landings & 125+ hours AV-8B, F-14 crew, royal dutch airforce F-16C - PvP campaigns since 2013 DCS server-admins: please adhere to a common sense gaming industry policy as most server admins throughout the industry do.

Oceandar Posted March 15, 2020 Posted March 15, 2020 I have not viewed your tracks tbh but I actually found it was the opposite. The SD-10 seems quite easily spoofed by chaffs as long as you drop quite amount of it and make correct notching manouver. I've done it few times and also saw some people done it succesfully.

foxwxl Posted March 15, 2020 Posted March 15, 2020 The ACMI is quite interesting. The normal ARH seeker model(from FC2 or even earlier) only accept chaff when target is very close to notch(and the allowable angle error is very small). If U drop chaff at any other angle, it's basically ignored by the ARH missile. SD-10 follows the same rule. The chaff resistance value on ARH usually resulting difference in the allowable angle error.(ie.AIM120C is around ±3degs, R77 is around ±6 degs).Since the angle is so small,it means U have to be VERY PRECISE to execute the notch and launch chaff at THAT time. U can successfully(basically 100%) spoof the ARH with chaff if you are in CORRECT notch angle and force the enemy radar into LOOKDOWN mode.(CHAFF should be dropped before U entering the notch and cover the exactly notch period) (Notch+lookdown+chaff, 3 conditions) U can also do this to SD-10, and U will success. Also,the SD-10 has poorer chaff resistance value in the config files compared with AIM-120, so basically it's easier to chaff the SD-10 than the AIM-120. This ACMI shows a very different condition that AIM120 do get chaffed while not in the notch. I can not tell how it happened.But AIM-120 do have some hardcoded features that does not fully obey the lua files, maybe this is a new seeker model feature. Deka Ironwork Tester Team
