Delay-Multiply-And-Sum Beamforming for Real-Time In-Air Acoustic Imaging
Wouter Jansen, Walter Daems, Jan Steckel
In-air acoustic imaging systems demand beamforming techniques that offer a high dynamic range and spatial resolution while also remaining robust. Conventional Delay-and-Sum (DAS) b…
nRTIS: Low-Cost Real-Time 3D Sonar Imaging Circular Array Supporting Beamforming for Industrial Applications
Rens Baeyens, Dennis Laurijssen, Jan Steckel +1
Conventional ultrasonic inspection systems rely on phased arrays and high-performance computing hardware, making them costly, bulky, and unsuitable for portable or embedded use. In…
High-Density MIMO Localization Using a 32x64 Ultrasonic Transducer-Microphone Array with Real-Time Data Streaming
Rens Baeyens, Dennis Laurijssen, Jan Steckel +1
In this work, we present a novel ultrasonic array system designed for high-precision localization using a large-scale MIMO (Multiple-Input Multiple-Output) architecture. The system…
A Wireless Self-Calibrating Ultrasound Microphone Array with Sub-Microsecond Synchronization
Dennis Laurijssen, Rens Baeyens, Walter Daems +1
We present a novel system architecture for a distributed wireless, self-calibrating ultrasound microphone network for synchronized in-air acoustic sensing. Once deployed the embedd…
