Cranking tactics and AESA

Professor John Roulston who was in charge of Eurofighter Typhoon’s CAPTOR radar claimed that “extreme gimbal angles (of a mechanically steered radar such as CAPTOR) are helpful in the launch-and-turn manoeuvre used by Typhoon in a long-range missile engagement” and “even the best AESA, with a fixed array, does not quite match the angular coverage of a gimballed radar” in a September 2004 paper according to Jane’s IDR September 2005.

As far as I know it’s true that a fixed AESA radar has a narrower angular coverage than a mechanically steered radar. But how true is his claim that a fighter with a mechanically steered radar has advantages over the one with an AESA in cranking tactics, which forces enemy missiles to manoeuvre with rapidly increasing line-of-sight rates?
