WebDynamic Time Warping (DTW) [7] is a technique which allows us to do this. It stretches (warps) the signals non-linearly by re-peating samples in each time series allowing us to ‘line up’ the early reflections. A warp vector is created for each time series which describes how the signals are stretched.
