SYSTEM AND METHOD FOR ADAPTIVE BEAMFORMING FOR IMAGE RECONSTRUCTION AND/OR TARGET/SOURCE LOCALIZATION

摘要

Methods, systems and computer readable media for reconstruction of target locations (2) and amplitudes from signals received from one or more real targets in a space are provided, wherein the signals are at least one of signals received from the near-field and broad band signals. The space is modeled as a region of interest, and an array manifold matrix is calculated from signals received from hypothetical targets in the region of interest. One or more signal vectors received from the one or more real targets are reshaped into a data vector. A hypothetical target configuration is identified (70) that, when applied to a signal model comprising the array manifold matrix, matches the data vector, a reconstruction vector is calculated. The reconstruction vector is reshaped into a reconstructed representation (74) of the real targets in the space, and at least one of outputting the reconstructed representation for viewing by a user, and storing the reconstructed representation for later use are performed.
