    Patent number: 7558673
    Abstract: The present invention provides a new approach for processing hyper-spectral radiance data. It uses a transformation matrix to convert an instrument radiance spectrum into a pseudo-monochromatic radiance spectrum. The pseudo-monochromatic radiance spectrum is produced by an empirical transform of the instrument channel spectrum to a monochromatic equivalent spectrum (i.e., a pseudo-monochromatic spectrum). Eigenvector regression is used to produce the empirical transformation. Although the transformation does not produce the monochromatic radiance spectrum without error, the transformation error is generally well below nominal instrument noise levels for most spectral channels. The reduction in instrument noise results from a noise filtering effect of the eigenvector transformation.
