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 ,…
Distributed Beamforming Using Decentralized Time Synchronization in a Six-Element Array
Naim Shandi, Jason M. Merlo, Jeffrey A. Nanzer
We demonstrate a distributed beamforming and beamsteering from a six-node distributed phased array using fully wireless coordination with decentralized time synchronization. In wir…
Wireless Picosecond Time Synchronization for Distributed Antenna Arrays with Dynamic Connectivity
Naim Shandi, Jason M. Merlo, Jeffrey A. Nanzer
Phase, time, and frequency coordination are crucial for the coherent operation of distributed antenna arrays. This paper demonstrates a high accuracy decentralized time synchroniza…
