Using Chaff

[Cintra]

Hi all.

 

Has anyone had luck with chaff actually doing its job? I feel like it does absolutely nothing at all. It doesn't deter my missiles from enemies or missiles from myself.

 

The other day I launched an AIM120 at a hornet which ALMOST hit him because it was flying about 5 meters RIGHT BEHIND HIM WHILE HE WAS SPAMMING CHAFF. The missiles was unfortunately too slowly to finish him off, although the heat from the engines should have set it off because of how close it was but nonetheless, it didn't lose its lock AT ALL while the person was dumping all the chaff he could the entire way.

 

So either Chaff is useless in real life or ED needs to maybe look at them when they have some time to do so.

 

Can anyone comment on this?

Really intensive chaff programs does have an effect and are able to defeat missiles. You should try with something like 20 chaff 0.25 seconds apart combined with some notching. In that case you have a very high probability of trashing a shot. On the other hand chaffs while cold are not very effective because im DCS missiles are "decoyed" for only a small fraction of time after which they reengage (or try to if you are still in his FoV), if you are cold you are moving in the same direction with respct to the FOV of the missile hence making really easy a re-engagement.

I see, I think then that I have over estimated the effectiveness of Chaffs... Still a bit tiring to get hit 9-10 times but if this is realistic then I can't say much.

 

Thanks for the reply.

Chaff is not a magical press to defeat missile thing!

 

It has to be combined with the proper geometry, manuevers to make it effective.

 

If you are flying straight at a a missile no amount of chaff will save you, same with a missile directly on your tail...

Yes, chaff does it’s job when you are notching perfectly, especially the slower you are

If you're using AIM-120C missiles as opposed to the older AIM-7 and R-27 jobs, assuming they're modelled in DCS with any degree of realism, it'll be a lot harder to spoof them with chaff.

 

Modern missiles aren't as dumb as older ones and are better at rejecting the chaff cloud and only tracking the actual target aircraft. Their radar units are designed to be able to tell the difference, instead of just blindly chasing after the biggest & juiciest radar return they can 'see'.

Chaff in DCS is nothing more than flares for radar-guided missiles, as far as I can tell. The main difference is that the missile will still receive guidance from the launching aircraft, so it might recover after it's spoofed once by chaff, if its receiver is able to pick up the reflected radar energy off of you. Have you ever seen radar returns from chaff on any radar in DCS?

 

IRL, chaff can form clouds that mess up not only missile guidance, but radar operation in general and it can stay up for quite a while, it doesn't disappear after a few seconds.
