Open-Loop Distributed Beamforming Using Scalable High Accuracy Localization [PDF]
arXiv, 2020 We present a distributed antenna array supporting open-loop distributed beamforming at 1.5 GHz. Based on a scalable, high-accuracy internode ranging technique, we demonstrate open-loop beamforming experiments using three transmitting nodes. To support distributed beamforming without feedback from the destination, the relative positions of the nodes in ...

AutoSAFT: Autofocusing for extended depth of imaging in scanning acoustic microscopy
Journal of Microscopy, Volume 298, Issue 3, Page 283-292, June 2025.Abstract In the scanning acoustic microscopy (SAM) imaging, it is essential to address the diminished lateral resolution in the out‐of‐focus region, as image quality correlates with the ultrasound propagation distance either above or below the focal plane.

Time Modulated Arrays Beamforming for Non-Terrestrial Network User Terminal
IEEE Open Journal of the Communications SocietyThough beamforming is the fundamental element of satellite communication, it incurs costs, complexity, and power consumption. In this paper, we study a Time-Modulated Array (TMA) beamforming design on the Non-Terrestrial Network (NTN) User Terminal (UT ...
