Abstract
A practical challenge that designers of hyperspectral (HS) target detection algorithms must confront is the variety of spectral sampling properties exhibited by various HS imaging sensors. Examples of these variations include different spectral resolutions and the possibility of regular or irregular sampling. To confront this problem, we propose construction of a spectral synthetic discriminant signature (SSDS). The SSDS is constructed from q spectral training signatures which are obtained by sampling the original target signature. Since the SSDS is formulated offline, it does not impose any burden on the processing speed of the recognition process. Results on our HS scenery show that use of the SSDS in conjunction with the spectral fringe-adjusted joint transform correlation (SFJTC) algorithm provides spectrallyinvariant target detection, yielding area under ROC curve (AUROC) values above 0.993.
