Abstract
A system and method for beamforming signals received in sparse, irregular sensor arrays has a network of sensors organized into sensor clusters, a signal processing node for each sensor cluster for beamforming the signals received by the sensors in each sensor cluster and an aggregation node for combining the beamformed responses from each sensor cluster to form a composite response characterized by minimized side lobes and grating lobes.
