AIM-9 loses growl depending on relative bank angle vs target

[SgtPappy]

I have noticed that the AIM-9s tend to have intermittent growling during maneuvers. It appears that this happens if you roll the F-4 relative to the target. In the first track, you will notice that despite the AIM-9J being uncaged, it will still lose lock when the F-4 is maneuvered. The other track shows the AIM-9J losing lock if the target is flying straight and the F-4 rolls side to side, implying the lock stability is a function of bank angle relative to the target.

I believe this is the case for the AIM-9B and AIM-9M, but I have yet to test them. I will attach tracks for other AIM-9 versions when I find time.

Please let me know if there are other tests I should perform.

Thanks!

Likely an ED topic. The tone is based on the signal strength reported through the DCS SDK. This part of the Sidewinder logic is controlled by ED.

(I personally dont know enough about the weapon to comment on this being correct behavior or not)

Ah good point, I keep forgetting to post weapon issues to the ED general forum as well.

Thanks for the reminder. I'll report to there too.
