On the Design of Planar Differential Microphone Arrays with Specified Beamwidth or Sidelobe Level

This paper investigates the problem of designing differential beam-formers with planar microphone arrays to achieve not only the desired target directivity pattern but also control the beamwidth (BW) or sidelobe level (SLL). We first discuss the target directivity patterns and express the Dolph-Cheb…
