A system for finding a transducer resonant frequency, comprising: an initialization unit (11), a phase determination unit (12), an interval hopping control unit (13), a hopping interval generation unit (15), a frequency output control unit (17), a phase collection unit (16), and a resonant frequency point acquisition unit (14). Each hop allows a search range to be reduced by at least half of that of the previous interval, thus allowing for reduced amount of searches. |
