The soft Calibration Technology of Multi-hydrophones Underwater
It has been analyzed about the influence of sensor disagreement error to time delay, and a correction method was proposed for multi-hydrophones. The same dynamic signal is inputted to hydrophones, and then a single-input/multi-output system is established using hydrophones output signal. By the mathematics characteristic of the power spectrum and the correlation analysis, we can get the transfer function of the input-output system and the characteristic difference of the sensors in this system. The conclusion that the smaller the phase lag with working frequency in some range, higher is the time measuring precision was proved by simulation.
