The parametric, or difference frequency, radiator appears to offer advantages over conventional facilities used for hydrophone calibration wide bandwidth from a single transducer, narrow beamwidths, and short pulse lengths. The combination of these characteristics promises simplification of calibration procedures and elimination or reduction of boundary-reflection problems. Experiments described measured the parametric-radiator performance for calibration purposes and highlighted its inherent problems. Author
