Abstract :
This paper presents a method to predict the uncertainty of a procedure for calibration of fully assembled array hydrophones in a shallow water environment. All error sources (due to measurement elements, instruments, background noise, calibration setup and environment) of the calibration procedure are defined and combine to predict the final calibration uncertainty theoretically. The methodology for predicting the calibration uncertainty is also validated using actual trial measurements in a shallow estuary.
