Infrared multispectral target/background field measurements

Extensive measurements of targets and backgrounds were made in the field by an infrared Fourier transform spectrometer. These measurements were made to provide statistically valid estimates of target to background spectral contrast and background spatial and spectral statistics to support the use of multispectral sensing techniques for detecting military targets in clutter. The details of the spectrometer, the targets, the backgrounds, and the measurements are given.
