Claim 9:
10. The method according to claim 9, wherein when the bidirectional microwave-over-fiber resonant system based on the circulator structure has a cavity length control system, frequency discrimination and phase discrimination are performed on the microwave frequency f1 in the counterclockwise direction assigned by the first microwave power divider (24) with an external clock reference source (45), and an output signal passes through a cavity length control unit (30) to control a cavity-length adjuster for counterclockwise resonant cavity length locking; and a cavity length change of the clockwise resonant cavity is a sum of a cavity length change of the clockwise resonant cavity before the cavity length locking and a cavity length change of the counterclockwise resonant cavity before the cavity length locking.
