Described is a system for library-based spectral demixing. The system simultaneously separates and identifies spectral elements in a set of noisy, cluttered spectral elements using Sparse Representation-based Classification (SRC) by modeling the set of noisy, cluttered spectral elements. The spectral library models each spectral element in the set of noisy, cluttered spectral elements, each spectral element having a corresponding wavenumber measurement. Wavenumber measurements are classified, resulting in salient wavenumber measurements. Target spectral elements representing a target of interest are identified in the set of noisy, cluttered spectral elements using the salient wavenumber measurements.
