This principle is demonstrated in small-scale geophysics using noise sources generated by human steps during a 10-min walk in the alignment of a 14-m-long accelerometer line array. The time-domain correlation of the records yields two surface wave modes extracted from the Green's function between each pair of accelerometers. A frequency–wave-number Fourier analysis yields each mode contribution and their dispersion curve. These dispersion curves are then inverted to provide the one-dimensional shear velocity of the near surface. %G English %L insu-00333892 %U https://insu.hal.science/insu-00333892 %~ INSU %~ UNIV-SAVOIE %~ UGA %~ CNRS %~ UNIV-GRENOBLE1 %~ INPG %~ IRSTEA %~ IFSTTAR %~ AGREENIUM %~ INRAE %~ USMB-COMUE %~ UNIV-EIFFEL %~ IFSTTAR-UNIVEIFFEL
