Signal Processing, Time-Frequency Analysis, Digital Communications Dr. Davidson joined the Laboratory in 2004 and his primary interests are applications of time-frequency analysis, machine learning applications in signal processing, and digital communications. He is currently investigating automatic detection and classification of sniper weaponry via gunshot acoustic signatures, and developing electromagnetic field signal processing techniques for detection, classification, and tracking of underwater targets. Previous research efforts include algorithm development for automatic identification and blind demodulation of communications signals, and classification of synthetic aperture radar (SAR) imagery via wavelet-based texture characterization. |
