In this article, we present a distributed and decentralized synchronization algorithm for
wireless sensor networks (WSNs). The proposed method achieves subnanosecond …

This article presents a design for implementing an ultrawideband (UWB) software-defined
radar (SDRadar) using a bandwidth reconstruction technique, called frequency stacking, for a …

We present results from a field campaign to measure seasonal snow depth at Cameron
Pass, Colorado, using a synthetic ultrawideband software-defined radar (SDRadar) …

Adaptive and targeted allocation of mobile sensing agents, in the form of unmanned aerial
vehicles (UAVs) with software defined radar (UAV-SDRadar) payloads, enable mapping of …

… This thesis is dedicated to my late father, Henry John Prager, who throughout my life
encouraged my interest in mathematics and physics, who I could always confide in and seek …

In this paper we demonstrate the capability of an ultra-wideband software defined radar (SDRadar)
implemented in commercial USRP SDR hardware to produce high-resolution images …

The ongoing Distributed Aperture Radar Tomographic Sensors (DARTS) project at NASA Jet
Propulsion Laboratory aims to mature and demonstrate multi-static SAR measurements for …

Recent innovations in small satellite, ultra-wideband direct RF sampling, and synchronization
technologies have made multistatic and MIMO coherent SAR constellations a feasible …

Recent results have highlighted the potential ability of bistatic and multistatic synthetic
aperture radar (SAR) tomographers to measure vegetation structure and surface topography. …
