Title: Low-Cost One-Bit MEMS Microphone Arrays for in-Air Acoustic Imaging Using FPGA's
Author: Robin Kerstens, Dennis Laurijssen, Jan Steckel

Abstract: In this paper we will propose an architecture for using these low-cost one-bit MEMS microphones to construct a microphone array and demonstrate their applicability in beamforming-based acoustic imaging algorithms targeted at 3D sonar sensors. We developed a small prototype array do demonstrate that these microphones are well suited for array applications, and the proposed system architecture, developed around an FPGA-SOC, is shown to be ideally suited to interface with a large number of these microphones.
