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…
Deep Reinforcement Learning Control for Radar Detection and Tracking in Congested Spectral Environments
Charles E. Thornton, Mark A. Kozy, R. Michael Buehrer +2
In this paper, dynamic non-cooperative coexistence between a cognitive pulsed radar and a nearby communications system is addressed by applying nonlinear value function approximati…
