Paper Title:
Configuration of Random Transducer Array in Irregular Region Based on Delaunay Triangulation
  Abstract

To realize the configuration of a cymbal transducer array in an irregular region, Delaunay triangulation is adopted to mesh the irregular region and the vertices of the Delaunay triangular mesh are regarded as the positions of the array elements. In this way, a random array of cymbal transducers is formed. Minimum Variance Distortionless Response (MVDR) beamformer is used to optimize the beam of the random array, and the directivity simulation is carried out in MATLAB. The results show that the directivity of the random array within the irregular region is better than that of the uniform linear array and that of the uniform plane array configured in the same region.
