1980's.
TANS (Tactical Air Navigation System) used Dopplar cross refer TANS to a radio beacon and update 'FIX' (DME/TACAN) in the overhead, followed by a set pattern to parallel the runway outbound at 1.5nm offset to begin a turn in at 7nm from the threshold. Pretty much an SRE talkdown but internally from the crewman.
Not forgetting the good old Decca let down (without the moving map). I never really understood how it was done, but thankfully most of the crewmen did!
