ABSTRACT:
A sensor includes a piezoelectric hydrophone and at least one accelerometer. In calibration mode, the hydrophone is connected to a source of a known electrical signal and outputs a mechanical/acoustic signal that the accelerometer detects. Comparison of the known electrical signal to the output of the accelerometer allows calibration of the accelerometer. In operation mode, both the hydrophone and the accelerometer are connected to a data acquisition unit.
