In this letter, a spherical-wavefront-based parametric signal model is proposed by considering the architecture using a large-scale antenna array. A space-alternating generalized expectation-maximization (SAGE)-based localization algorithm is derived and adopted to localize the first- and last-hop scatterers along the propagation paths between the transmitter and the receiver. Simulations are conducted to evaluate the performance of the localization algorithm. An outdoor measurement campaign with a 1600-element virtual planar array is carried out to verify the localization performance in reality. Those results show the advantages of using a spherical-wavefront-based signal model and the SAGE-based algorithm in the scatterer localization.
