Secure Wireless Communication Using Coherent Distributed Transmission and Spatial Signal Decomposition
Anton Schlegel, Jason M/ Merlo, Samuel Wagner +2
We present a new approach to secure wireless communications using coherent distributed transmission of signals that are spatially decomposed between a two-element distributed anten…
Passive Microwave Tag Classification Using RF Fingerprinting and Machine Learning
Cory Hilton, Mohammad Rashid, Faiz Sherman +2
We present an approach to identifying wireless microwave tags using radio frequency (RF) fingerprinting and machine learning. The tags are designed for low cost and simplicity, con…
Three-Dimensional Millimeter-Wave Imaging Using Active Incoherent Fourier Processing and Pulse Compression
Jorge R. Colon-Berrios, Jason M. Merlo, Jeffrey A. Nanzer
We present a novel three-dimensional (3D) imaging approach that combines two-dimensional spatial Fourier-domain imaging techniques with traditional radar pulse compression to recov…
Collaborative Beamforming for Communication Applications Using a Two-Element Fully-Wireless Open-Loop Coherent Distributed Array
Jason M. Merlo, Jeffrey A. Nanzer
In this work we demonstrate a proof of concept of a fully-wireless two-node open-loop coherent distributed communication system and evaluate its performance by transmitting QPSK ,…
