  • Abstract
    Spherical near-field scanning is often used in electromagnetics. The acoustical analog is outlined. Data are taken, with an arbitrary probe, on a spherical surface surrounding an unknown transducer. The algorithm uses these data to characterize the fields of the transducer everywhere outside the measurement sphere. The results can be corrected for probe effects if the probe´s receiving pattern is known
