Velocity Information Geometry of Coherent Intra-CPI Waveform Agility
Charles E Thornton
Spectrum sharing forces radars to vary carrier frequency and bandwidth on a pulse-to-pulse basis within a coherent processing interval (CPI). While the resulting range-Doppler dist…
Linear Jamming Bandits: Learning to Jam 5G-based Coded Communications Systems
Zachary Schutz, Daniel J. Jakubisin, Charles E. Thornton +1
We study jamming of an OFDM-modulated signal which employs forward error correction coding. We extend this to leverage reinforcement learning with a contextual bandit to jam a 5G-b…
On the Value of Online Learning for Radar Waveform Selection
Charles E. Thornton, R. Michael Buehrer
This paper attempts to characterize the kinds of physical scenarios in which an online learning-based cognitive radar is expected to reliably outperform a fixed rule-based waveform…
Online Learning-based Waveform Selection for Improved Vehicle Recognition in Automotive Radar
Charles E. Thornton, William W. Howard, R. Michael Buehrer
This paper describes important considerations and challenges associated with online reinforcement-learning based waveform selection for target identification in frequency modulated…
When is Cognitive Radar Beneficial?
Charles E. Thornton, R. Michael Buehrer
When should an online reinforcement learning-based frequency agile cognitive radar be expected to outperform a rule-based adaptive waveform selection strategy? We seek insight rega…
Timely Target Tracking in Cognitive Radar Networks
William W. Howard, Charles E. Thornton, R. Michael Buehrer
We consider a scenario where a fusion center must decide which updates to receive during each update period in a communication-limited cognitive radar network. When each radar node…
