3-D temporal-spatial-based near-field source localization considering amplitude attenuation

•A three-dimensional (3-D) temporal-spatial-based localization algorithm of multiple near-field (NF) sources considering amplitude attenuation is proposed.•The symmetry of the array and the delay autocorrelation of NF signals are exploited to construct virtual received data.•Two one-dimensional (1-D) peak search estimators are constructed to obtain the one angle and range parameters, and the procedure of pseudo peak identification is proposed.•The remaining angle parameter is solved by phase-taking operation, and the 3-D parameters can be automatically matched.
