Dynamic range extension for heterodyne fibre‐optic hydrophone by using instantaneous frequency‐tracking method
Abstract This letter proposes a novel dynamic range extension method using an instantaneous frequency (IF)‐tracking method for heterodyne fibre optic hydrophones (FOHs). IFs are used to compensate for large signal amplitudes in the demodulator. Theoretical analysis and simulation prove the effective...
