Abstract

Distributed fiber vibration sensing system is widely used in the field of wide area security, communication cable of long distances and pipeline security. The principle of the system is that for a vibration signal applied at a particular position along the fiber, the response, in the frequency domain, presents a series of periodic maxima and minima (or nulls). These minima depend on the position of the vibration along a fiber. Power spectral estimation method is considered to denoise the power spectrum of the system and determine these minima precisely in the paper. The parametric modelling methods such as autoregressive-moving average (ARMA) model is used to improve the positional accuracy of the system. The experimental results show the high accuracy of the position using ARMA model.
