 | Multicolor infrared imaging missile-warning systems require real-time detection techniques that can process the wide instantaneous field of regard of focal plane array sensors with a low false alarm rate. Current technology applies classical statistical methods to this problem and ignores neural network techniques. Thus the research reported here is novel in that it investigates the use of radial basis function (RBF) neural networks to detect sub-pixel missile signatures. An RBF ... |

| The band offset of Si(1-x-y)Ge(x)C(y)/Si in pseudomorphic structures grown on Si(100) substrates has been experimentally measured by using both electrical (capacitance-voltage) measurements and by making heterojunction internal photoemission (HIP) infrared detector. By measuring the cutoff wavelength of the IR detectors, one makes a direct measurement of the valence band offset. The two methods are in good agreement with each other, and find that as carbon is added to these structures, ... |

| The purpose of this work is to develop a basis for irradiance calibration of space-based infrared sensors. It is an extension of previous work that fully defines the context of the calibration, and the concepts of spectral composites and templates. We discuss four major accomplishments during the past year and our plans for the future. The accomplishments are: 1) Data from the MSX/SPIRIT III CBO6 celestial background calibration experiments have ... |
