Since the missile is coming from the launching aircraft, both of them will be on roughly the same bearing; certainly early on. Flying perpendicular to that bearing will thus (hopefully) result in both sets of radar electronics filtering you out. Should the two bearings diverge at some point, I'd recommend notching against the one armed with the explosive warhead with your name on it.
