My understanding is that if the chaff is released when it is completely COLD, it should cut the LOS with the missile, but this does not happen in the game.
I am also aware that the chaff can shift the tracking center backward.
If my understanding is wrong, I would like to know.
So with radar evasion a few things to take into account :
RCS of the vehicle (buggy at most in WT)
Time to Target - AT what range the missile has been fired & at what point does the missile go pitbull
Radar type
Guidance type
Chaff Type (this also matters for IR weapons & flares)
Basically, plane VS tech VS design doctrine.
There are a few things to consider here
Most radar missiles have some form of IOG, meaning if they lose sight of the enemy, they will go towards their last known intersection point and try to require the target. that means that if chaffs for some reason prevent the missiles from seeing you for a fraction of a second, the missile will still require the target.
And you can’t have the missile being you at all times
That’s why to use chaff I would recommend to notch, not go cold… If you go side way in a good notch (so missile seeker is in its worse viewing angle), chaffing helps the lock center to go backwards, and with some luck the sight of the missile loses the plane completely and goes for the chaffs. That’s how notching chaff is the most effective way of making a missile lose you (along with multipath, or defeating it kinetically)
yeah i know notching… I mean split second of chaff has almost same speed as aircraft. this means you can defeat PD without notching but about very narrow time to shift the tracking center backward…?
I don’t think this is possible due to the missile inertial navigation system. If you go cold you should rely on cranking to kinematically defeat the missile. Below 20-15km, going cold will not work, you need to rely on notching or multi path in this instance
which reminds me in real life they have ECM to use Velocity gate pull-off (VGPO) so chaff is very deadly for missiles,
so I think I have to wait ECM features to work chaff without notching i guess?
one more thing I care about is In reality, chaff is used to blind the radar, but in war thunder it is a problem because it disappears within few seconds.
I’ve noticed this as well and it’s rather annoying. I wish to see some further explaination on it
