Rejection of a Coherent Arrival at an Array
Victor C. Anderson, Philip Rudnick · The Journal of the Acoustical Society of America · 1969
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.
