Simultaneous two-sphere two-transducer calibration
Original version
This report is not to be cited without prior reference to the authorAbstract
When directional transducers are mounted nearby, the central lobes of
their beam patterns may partly overlap at ranges typical for standard-target
suspension in calibration exercises, e.g., 20 m. According to the proposed
technique, two transducers may be calibrated simultaneously by a two-sphere
suspension. This will be most workable for split-beam transducers.
