Abstract

En 中文

• A method is proposed to enhance acoustic imaging low-frequency source localization. • Kriging interpolation is used to virtually increase the microphone count. • Acoustic holography is used to virtually enlarge the microphone array. • A parametric study determines how to optimally set virtual array parameters. • The method localizes 150 Hz sources using a 30-mic array of 9.75 cm radius.
