An Accelerated Adjustment Method for Directivity Pattern of Microphone Array Based on KKT Condition

Abstract (in Japanese) (See Japanese page) 
(in English) For a high S/N sound capture, it is effective to form a directivity pattern of a microphone array.
However, it is necessary to adjust the directivity pattern with time for moving sound sources.
In this study, an accelerated redesign method using the designed directivity pattern is proposed for the moving sound sources.
In the redesign, null directions for interference sources and a beam direction for a target sound source are adjusted based on KKT (Karush-Kuhn-Tucker) condition.
Several redesign examples are shown to present the effectiveness of the proposed method.
