This paper proposes a microphone array with a speaker to recognize the shape of the surface of the target object by using the standing wave between the transmitted and the reflected acoustic signals. Because the profile of the distance spectrum encodes both the distance to the target and the distance to the edges of the target's surface, this paper proposes to fuse distance spectra using a microph...
