Orbital Plane Geometry and Information Conditioning for Doppler-Only LEO Positioning
Charles E Thornton
We study an idealized information model for Doppler-only positioning with low earth orbit (LEO) signals of opportunity from a stationary receiver. Motivated by the observation that…
Hierarchical Federated Learning for Unsupervised Waveform Classification over Tactical MANETs
Charles E. Thornton, Daniel J. Jakubisin
Distributed radio frequency sensing in contested tactical environments demands collaborative learning across mobile nodes. In ad-hoc networks, learning must occur without persisten…
Temporal Convolutional Autoencoder for Interference Mitigation in FMCW Radar Altimeters
Charles E. Thornton, Jamie Sloop, Samuel Brown +3
Reliable altitude estimation with frequency-modulated continuous wave (FMCW) radar altimeters is increasingly a challenge due to in-band interference from modern communication syst…
Aircraft Radar Altimeter Interference Mitigation Through a CNN-Layer Only Denoising Autoencoder Architecture
Samuel B. Brown, Stephen Young, Adam Wagenknecht +4
Denoising autoencoders for signal processing applications have been shown to experience significant difficulty in learning to reconstruct radio frequency communication signals, par…
On the Role of 5G and Beyond Sidelink Communication in Multi-Hop Tactical Networks
Charles E. Thornton, Evan Allen, Evar Jones +3
This work investigates the potential of 5G and beyond sidelink (SL) communication to support multi-hop tactical networks. We first provide a technical and historical overview of 3G…
