摘要：
Acoustic sensing technology in air is a promising method for acquiring the shape and/or position of a target. Universal and smart technology, however, cannot be sufficiently established because of various acoustic environmental noises, attenuation effect, and so forth. To overcome this problem, in this study, we propose acoustic sensing that combines a super-directivity speaker and super-resolution signal processing. Our experimental results suggest that the proposed method enables long-range high-resolution acoustic imaging. (C) 2017 The Japan Society of Applied Physics
