A system and method for increasing the effective angular resolution of a multi-function phased array radar system is provided. The system is operative to simultaneously transmit a plurality of overlapping sub-beams covering a representative central beam. A de-convolution process is applied to received return signals. The process includes determining the reflectivity within sub-beamwidth resolution cells defined by the overlapping sub-beams. Generated sub-beamwidth data provides the radar system with an effective angular resolution beyond that of any single transmitted beam.

Enhanced-resolution phased array radar

A method of beam forming an array, by computer processing a cross covariance, of the reference sub array seismic signal data signal, by having an unknown shape comprising receiving acoustic signals, via the array, and computing the data and segmenting the array into an initial segment of a known shape and at least a second segment, and beam forming the initial segment to provide a beam formed output, and using the beam formed output to obtain weights, for the second segment of the array.
