Download or read book Thermal Infrared Characterization of Ground Targets and Backgrounds written by Pieter A. Jacobs and published by SPIE Press. This book was released on 2006 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition updates the technologies that deal with the characterization of the thermal infrared radiation contrast between ground targets and backgrounds. Samples have been updated to comply with the current status of technology in sensor systems and countermeasures. New topics on mine detection and polarization have been included, and the section covering multispectral camouflage of personnel has been extended. The basic principles and meteorological parameters are presented, followed by calibration procedures, signature measurements, and data analyses.
Download or read book Absolute Identification of Color for Targets Presented Against White and Colored Backgrounds written by Harold P. Bishop and published by . This book was released on 1961 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The number of stimulus colors which can be absolutely identified by normal subjects when viewed against various colored backgrounds was investigated. Additive mixtures of light passed through narrow-band and Illuminant-C filters were projected onto a viewing screen by a device wich permitted independent control of target and background characteristics. The stimulus parameters of hue, luminance, purity, target size, and target shape were varied, and the effects of such factors as training and the presence of a distracting task were studied. With target luminance above background luminance, about nine hues plus white, three luminance levels, and two purity levels, are estimated to be useful for operational coding, if no more than about 30 of the possible combinations are included in the set. Under optimal working conditions and with protracted training, the maximum size of an identifiable set is estimated to be about 60. Reduction of target luminance below the luminance of a colored background was found to make identification very difficult. No significant effect of target shape was found. (Author).

This book was released on 1971 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study investigated the hypothesis that sequential changes of background color on a simulated radar display enhances target detectability. Two experiments were conducted wherein target detectability was assessed in terms of the accuracy in which subjects determined the presence of a randomly appearing target symbol imbedded in visual noise. The first experiment tested 30 subjects to determine the relative detectability of targets among display backgrounds of homogeneous color and backgrounds presenting abrupt changes of color. The second experiment tested 24 subjects to determine if the speed and/or sequence of background color change affected target detectability. Results of the study showed that homogeneous green or blue backgrounds significantly enhanced target detectability when compared to the sequentially changing colored background, and that speed and sequence of background color change have little effect. The study also showed colored backgrounds to enhance target detectability when compared to the conventional method of radar display. (Author).
