Abstract:

Absolute spectral radiance signatures of a number of natural backgrounds have been measured in the following wavelength regions Near - UV 0.30 - 0.44 micron, MID - IR 1.5 - 5.4 and 2.0 - 5.4 micron, LWIR 2 - 13 micron. The infrared data were obtained using an interferometer with high spectral and spatial resolution while the near-UV data were acquired using a dispersive-prism spectrometer. In addition to the individual background spectra, spectral contrast plots are presented for spatially adjacent background areas. These contrast plots can be used in conjunction with target spectra to derive optimized spectral regions of operation for target detection systems. Also included are photographs illustrating the spatial appearance of the various background areas in appropriate wavelength bands. Author
