ABSTRACT:
In this paper, the author analyzes characteristics and
extracting method of interference signal of the distributed optical fiber
sensing. In the distributed optical fiber sensing, realizing alarm and
positioning function only through the cross-correlation
operation will increase the load of the system, can make misinformation rate of
the system be improved greatly. Therefore, before the localization algorithm, adding
a interference signal feature recognition is very necessary, can reduce
unnecessary operation loss and reduce the load of the system, also reducing the
number of the false positives.
