Abstract :
Data processing of Terahertz signals for reliable explosives detection via Terahertz time-domain spectroscopy is investigated. Wavelet denoising, wavelet power spectrum estimation, and wavelength selection show promising results. Experiment results for Composition B-3 and Pentolite are presented.
