MICROPHONE ARRAY FOR DIRECTIONAL ACOUSTIC ANTENNA IMPLEMENTATION
Annotation
A new method of signal processing in microphone array is proposed. The array consisting of two identical omni-directional microphones is considered; the array receives signals from two broadband acoustic sources located in different angular positions relative to the array. The proposed method provides directional reception of signal from one source and attenuation of the other source signal. Mathematical expressions for microphone array weight coefficients are presented.
