摘要
A method to derive, design and apply digital signal filters to compensate for variations in hydrophone sensitivity. The impedance or resonance of a hydrophone is measured and compared respectively to the impedance or resonance values from a library of hydrophone responses containing values for impedance, resonance, amplitude sensitivity, phase response, or other hydrophone characteristics. A corrective filter is determined based on library values, and this filter is applied to the data collected by the hydrophone.
