Target detection using HSI systems: an update of TRW results

Hyperspectral imaging (HSI) systems have the potential for tremendous military utility. The ability to use detailed spectral information to characterize objects that may be sub-pixel in size enables efficient surveillance and terrain characterization over wide areas. TRW is actively involved in all aspects of HSI systems form building hyperspectral sensors and real-time processors to the development of processing algorithms. This paper presents performance results on hyperspectral imagery data for target detection. Whereas a recent paper presented results for the detection of known targets, this paper focuses on anomaly detection algorithms for application in those situations involving a high degree of target uncertainty or poor knowledge of atmospheric effects.
