Abstract

In this paper, a new scheme for delay parameters measurement in time division multiplexing (TDM) fiber optic interferometric sensor (FOIS) network is proposed. This scheme provides a solution of delay parameters measurement through the variance vector of the reshaped original data. By calculating the correlation between the variance vector and the system's pulse template vector, the scheme is capable to resist much more noise in the original data. Even when the SNR of the original data decreases to 7 dB, the scheme can still work with a correct rate higher than 98%. What's more, the scheme is feasible to be carried out, and it is able to work real-time.
