Patent ID: 7430407

Claim:
A circuit operable to perform a method of improving an angular resolution in a receive system, said method comprising: aggregating signal-plus-noise data output from an antenna into a plurality of groups, each group containing data having a similar phase, wherein the phase corresponding to each group is a multiple of the phase corresponding to the other groups, said multiple being determined by a spacing between right and left elements of each group from the center of the antenna array and wherein further, said groups are formed by combining data from respective right and left antenna elements and said right and left antenna elements are equidistant from a central common reference located at a center of the array of elements and corresponding to a phase angle, phi, of zero phase; and iteratively processing the data in said group to reduce a noise portion of a signal plus noise average to determine a relatively noise-free representation of the angle, phi, associated with an arrival direction of the signal from said group by aggregating modified quadrature data (Q) and aggregating in-phase data (I) and dividing the overall digital net values of plus and minus quadrature data by the net in-phase value to determine an angle from the arctangent of each Q/I quotient.
