A Design of Uni-Directional Array-Microphone using Directional Microphone Units and Two-Dimensional FIR Filter

Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a method for designing uni-directional broadside array-microphone of all digital constitution using directional microphone units and two-dimentional(2-D) FIR filter.
As the directional microphone, a pressure-gradient microphone unit is employed to perform the uni-directivity. 2-D FIR filter is designed by mapping the frequency response of the unit into the 2-D frequency area. An example demonstrates the good uni-directivity and the wider responces.
