Use an aircraft with 4AAM or 6AAM. When you activate DFM, go directly into afterburner. Be careful of the flames, especially under the Elite difficulty setting. Try to move to the right side of the missile. You will find an opening where you will not get damaged, but it will begin to close after the second missile. Try to pull away to the right when you start getting damaged. You will get missile lock in DFM, even when you are pulling away from it to dodge the missiles. About seven missiles are required before the mission ends.
