A method and system for analyzing noisy terahertz spectroscopy data transforms the measured time-dependent data into frequency space, for example, using a discrete Fourier transform, and then transforms the frequency spectrum into wavelet frequency space. The twice-transformed data is analyzed to identify spectroscopic features of the signal, for example, to identify a resonance frequency. The method may be used, for example, in a stand-off detector to identify particular chemicals in a target. |
