Paper Abstract

We need high-pass filtering in interferometric fiber-optic hydrophone system. In this paper, two methods of zero-phase high-pass filtering are introduced. The two methods are based on infinite impulse response (IIR) filter and frequency filtering alternatively. They can both shorten the data processing time compared to finite impulse response (FIR) filter on the expense of memory cost, which is also discussed in this paper.
