Abstract
A system and method to receive correlated input signals from targets from antennas in a linear or planar antenna array, receive coarse estimations of azimuth and/or elevation angles for the targets, apply a semi-randomized signal permutation and reference selection algorithm to the correlated input signals to construct a virtual array information matrix (VAIM) by shifting a reference point of each of the correlated input signals in a different manner from one another to separate the correlated input signals from one another in a signal space in the VAIM, and filter the VAIM to independently extract information of the coarse estimations from the VAIM for each specific azimuth angle or elevation angle to transform the VAIM to provide filtered output signals corresponding, respectively, to filtered versions of each of the coarse estimations of the at least one of azimuth angles and elevation angles for each of the targets.
