<p>The first thermal imagery from the Spatially Enhanced Broadband Array Spectrograph System (SEBASS) was analyzed for target detection purposes. Data were acquired during Exercise WESTERN RAINBOW in October of 1995 with Aerospace Corporation's new instrument. SEBASS is a thermal infrared spectral imaging system which collects data in 128 wavelength bands from 7.8 to 13.4 micrometers. The system has 128 spatial pixels and a ground sample distance of 2.5 feet under the operating conditions of the exercise. The data reduction process included thermal calibration using on-board calibration sources, atmospheric correction through the use of in-scene data, and derivation of thermal emissivity. Analysis of the data was performed using techniques adopted from hyperspectral imagery. The application of the principal components transformation, the spectral angle mapper, and a spectral matched filter showed substantial enhancement of target detection capabilities when compared to the analysis of standard infrared imagery.
