Abstract
There is described a method of locating an area of interest in a conduit, comprising: measuring multiple acoustic signals at multiple locations along the conduit; for each acoustic signal, determining its autocorrelation; and applying a relationship to the determined autocorrelations to estimate a location of the area of interest, wherein the relationship is between autocorrelations of acoustic signals measured in a modelled conduit and modelled areas of interest in the modelled conduit, wherein it is assumed that acoustic signals propagating along the modelled conduit reflect from at least one point in the modelled conduit.
