There has been significant research devoted to the development of distributed microwave
wireless systems in recent years. The progression from large, single-platform wireless …

Cohesive Distributed Satellite Systems (CDSSs) is a key enabling technology for the future
of remote sensing and communication missions. However, they have to meet strict …

We present an open-loop microwave distributed beamforming system using a self-mixing
circuit for wireless frequency synchronization between two transmitting nodes in relative …

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 …

A decentralized approach for joint frequency and phase synchronization in distributed
antenna arrays is presented. The nodes in the array locally broadcast their frequencies and …

We present an adaptive approach for synchronizing both the phase and frequency of radio
frequency transceivers over 90 m wireless links to support distributed antenna array …

Radar tomography of glaciers promises to improve imaging and estimates of subsurface ice-
sheet structures and properties, including temperature distributions, basal materials, ice …

This article presents a wideband phase-locked loop (PLL) with a novel frequency acquisition
loop for a wide locking range and wide bandwidth in 130 nm SiGe BiCMOS technology. The …

We demonstrate a new approach to implementing directional modulation that leverages
distributed array dynamics to change the antenna array pattern over time. With appreciable …

Traditional single-antenna systems have inherent limitations in terms of antenna gain, anti-
interference capability, and flexibility. To overcome these challenges, satellite-mounted …
