Abstract
A method including receiving from multiple transducers respective signals comprising reflections of a transmitted signal from a target; processing the received signals to derive a beamformed signal, based, at least in part, on: (i) computing a specified value associated with each of the received signals, (ii) performing a convolution on all of the specified values, (iii) calculating a weighted sum of the results of the convolution, to derive the beamformed signal; and reconstructing an image of the target, based on the beamformed signal.
