1. A method for reconstructing signals distorted by multipath propagation, wavefronts assignable to signal components being received by a centrosymmetric sensor group having sensor elements, having two measures to be carried out separately, comprising the steps of:

  • in a first measure, determining incidence direction of wavefronts associated with respective dominant signal components ignoring lower-power signal components and interference components by utilizing phase differences occurring between the sensor elements with respect to a wavefront, and reconstructing the dominant signal components; and

    in a second measure that is carried out separately from the first measure and utilizing the dominant signal components reconstructed according to the first measure, assigning the determined dominant signal components to associated spatially separate signal sources and reconstructing the signals by combination of signal components associated with a signal source.
