Towards In-Air Ultrasonic QR Codes: Deep Learning for Classification of Passive Reflector Constellations
Wouter Jansen, Jan Steckel
In environments where visual sensors falter, in-air sonar provides a reliable alternative for autonomous systems. While previous research has successfully classified individual aco…
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…
Dynamically Tunable Helical Antenna
Ethan Chien, Jan Steckel
Unmanned aerial FPV systems demand ultra-low latency, high-reliability communication links. At high speeds and in cluttered environments, Doppler shifts and rapid multipath changes…
Phase-Center-Constrained Beamforming for Minimizing Phase-Center Displacement
Jan Steckel, Noori BniLam
Accurate knowledge and control of the phase center in antenna arrays is essential for high-precision applications such as Global Navigation Satellite Systems (GNSS), where even sma…
