I'm well familiar with Doppler notching and missile evasion. However in the accounts I was speaking about it was cases where they turned around and departed the area. Follow up conversations with some of these crews (which included Iraqi pilots, Libyan pilots to name a few) said that once they had seen the transition from being hit from search radar to acquisition radar they didn't want to provoke any further and chose to exit the engagement. Remember that during the 1980s the Phoenix AIM-54 had a scary reputation for it's range as well as the later AIM-120.
