There was this supplement in AFM a few years back on the EF.. and it had a fairly good explanation on why you cant use the towed decoy with an air to air missile.. cant recall what it was though.
Simple: The AAM can approach from any angle, not just the rear.

The only way a plain towed decoy would work would be if the decoy was MUCH larger in RCS than the airplane. ..................
No just the size of the RCS. It is possible to add smart differentiation of RCS against the adversary expected.
The only way a plain towed decoy would work would be if the decoy was MUCH larger in RCS than the airplane. That's easier said than done. But if you add electronics to the decoy, then yes, I can see that.
People still think missiles chase airplanes around the sky. It absolutely does not work that way. A missile's algorithm predicts where the target will be at intercept, finds that imaginary point in the sky, and flies to it. If, along the way, the target alters course, a new intercept point is computed. This update is fast and continuous.
Let's say the target is a mile ahead of you, and enters a break turn. You fire a missile. The missile will immediately cut across the circle. It looks like it's not going to work, but like magic, the missile meets the airplane on the turn circle way off to one side or the other.
The only realistic defenses are electronic, thermal (flares), chaff, and a towed decoy.
Armor is too heavy. A system like Trophy, also too heavy, and too complicated. The best defense is stealth, and to kill him before he kills you.
Oh yes, the graphic that has the Su defeating the Hornet using an IRST launch is pure fantasy. AMRAAM hugely outranges IRST, and IRST fails in clouds or dust.
........... With advanced digital processing these days, I suspect that a search radar will be able to differentiate. That is why I think a decoy must be smart and have it's own EW system which can augment or spoof.

Sir, I appreciate the innovative idea, but modern BVRAAM can travel mach 4-5.
much faster then a bullet, hitting a target moving that fast, lining up a shot when your target s at that speed, chances of success are slim at best, another problem is after a successful hit, you will see you plane fly though fireball, not ideal.
