Two-way Time-transfer Digital Design for Distributed Array Operations

In the Flat Field: Did Russian Army Electronic Warfare underperform in Ukraine? Since the Russian government began to overhaul its military early last decade, fears in NATO and allied nations have deepened over the efficacy of its army's electronic warfare systems.

New capabilities have been deployed and supported previous Russian military adventures in Georgia, Ukraine and Syria with seemingly great effect. The world's media has shared photographs of fearsome looking equipment deployed in rural farmland.

This time, however, things seem different. The army's EW capabilities appear conspicuous by their absence since Russia invaded Ukraine on 24th February. While the force has performed electronic warfare it does not seem to have been anywhere near as ferocious as anticipated. Moreover, the Russian Army has failed to win and sustain electromagnetic supremacy.

This webinar will look at the Russian Army's war in the electromagnetic spectrum. It will draw tentative conclusions as to why the force's EW capabilities may have underperformed. It examines the resulting implications for NATO and allied nations."

Speaker and Presenter Information

Jonathan D. Chisum received the Ph.D. in Electrical Engineering from the University of Colorado at Boulder in Boulder, Colorado USA, in 2011. From 2012 to 2015 he was a Member of Technical Staff at the Massachusetts Institute of Technology Lincoln Laboratory in the Wideband Communications and Spectrum Operations groups. His work at Lincoln Laboratory focused on millimeter-wave phased arrays, antennas, and transceiver design for electronic warfare applications. In 2015 he joined the faculty of the University of Notre Dame where he is currently an Assistant Professor of Electrical Engineering. His research interests include millimeter-wave communications and spectrum sensing using novel and engineered materials and devices to dramatically lower the power and cost and enable pervasive deployments. His group focuses on gradient index (GRIN) lenses for low-power millimeter-wave beam-steering antennas, nonlinear (1-bit) radio architectures for highly efficient communications and sensing up through millimeter-waves, phase-change materials for reconfigurable RF circuits for wideband distributed circuits and antennas, and microwave/spin-wave structures for low-power and chip-scale analog signal processing for spectrum sensing and protection. Dr. Chisum is a senior member of the IEEE, a member of the American Physical Society, and an elected Member of the U.S. National Committee (USNC) of the International Union or Radio Science's (URSI) Commission D (electronics and photonics). He is the current Chair for USNC URSI Commission D: Electronics and Photonics and is an Associate Editor for IET Electronics Letters.
