Abstract
The Hyperspectral Imaging Method and Apparatus provides the means of locating materials of economic and military value and accurately determining their spatial location and extent. The identification of a material is made by comparing its surface spectral reflectance properties in a scene with a set of reference template spectra. If there is enough spectral difference between materials of interest such as, for example, camouflage and vegetation or healthy and blighted corn, a detection will be made. The determination of spatial location and extent is may by the rapid collection of spectral measurements (nominally tens of thousands per second) in the form of an image and the reference of this image with GPS position to very high accuracy. Target identification and geolocation is computed in near realtime or realtime.
