Suboptimal suppression of directional noise by a sensor array before beam forming

Suboptimal suppression of directional noise before beam forming is possible by a random choice and attachment of partner elements for the respective estimation and elimination of the noise in each sensor channel of an array. Beam switching can take place independently of an adaptation against the directional noise. The adjustment of the weighting for the partner elements may be performed by stochastic approximation or analog control loops.
