I didn’t say it was locked on the chaff, the last return was from the chaff although ambiguous, it could no longer see the plane. Last known aircraft position is roughly in the location of the chaff so the IOG will default there. Additionally, pulse doppler radars can lock onto the chaff if the cloud is large enough. I believe @InterFleet may be able to explain better.
But the missiles do not continue on an IOG path, they manuever into the chaff cloud, instead of maintaining intercept vector with the notching aircrafts last known direction.
Reread what I said. It is clear you are not understanding.
I don’t think I am explaining myself well enough. Here is an illustration of what I mean. The missile doesn’t seem to continue toward the last predicted intercept point via IOG, instead it seems to maneuver into the chaff cloud.
Can you provide a video demonstrating the issue? Chances are the missile is indeed flying towards the chaff cloud, which is the last enemy position… not the previous point of impact. This is because as I said the missile is completely obstructed by the chaff cloud and can no longer see the target. It will fly for a certain amount of time towards the targets last known position and then drop the inertial guidance as it searches for the target again. Often times if this is in close quarters or final approach the target is already beyond the gimbal range of the missile and it will not find the track again.
