Abstract
Initial data and target data are frequency-analyzed to obtain an initial Rayleigh-scattering spectrum (RSS) and a target RSS, respectively. A distance correction is performed for the target RSS by comparing the target RSS with the initial RSS, and a Rayleigh spectrum shift is determined on the basis of a correlation coefficient between the initial RSS and the target RSS after distance-corrected.
