Analysis is presented for the enhancement of a plane-wave signal at an acoustic array relative to noise of which a part is also a plane wave from another direction. The process considered (described in the preceding paper) employs conventional beam forming to estimate the interfering plane-wave form, which is then removed at each element by subtraction. Removal of interference by more than one plane wave, and the relation to optimum beam forming, are briefly considered.
Anderson et al. (Sat,) studied this question.
