Optimized Design of Wideband Beamformer Using Interpolation Technique for a Vertical Acoustic Array
This paper is mainly an optimized design process about vertical acoustic array which is used in the far-field condition.It is difficult to design Acoustic arrays for a wideband signal covering several octaves,we needs spatial resolution which causes some signals to be received.One solution to this problem is to use relevant nesting and array interpolation in some precise sensors,excellent character is demonstrated.The robust interpolation matrix design is derived and solved using the second-order cone programming (SOCP).An interpolated wideband constant beamwidth beamformer (WCBB),which applied for the frequency domain have a good performance.
