| Zusammenfassung | Two methods for the amplitude and phase calibration of hydrophones based on time-delay spectrometry are presented. A time gating technique and heterodyne frequency conversion allows the phase-locked, i. e. coherent detection of hydrophone signals. Amplitude and phase of the hydrophone sensitivity are obtained in the frequency range 1 - 20 MHz. In addition, to show the broad-band capabilities of the methods, amplitude values are measured between 4 and 50 MHz. |
