Thank you for the explanation and drawing. If this type of weapon was used it should be possible to find debris from the rods ring, even if very far from the crash location. It should have a peculiar look, that even without mentioning the guiding head. It is also possible that Iran authorities want and manage to keep such a finding secret, although from images one can't see significant military presence.
