Abstract

A series of infrared hyperspectral field measurements was made at Wright Patterson Air Force Base and the U.S. Army White Sands Missile Range by the Joint Multispectral Program (JMSP) between November 1993 and June 1994. In these experiments, a highly sensitive Fourier transform spectrometer (FTS) was used to collect data from test panels, military and civilian vehicles, and various types of natural backgrounds. Post-collection data analyses are being conducted by the JMSP to assess the potential of thermal multispectral processing for detecting and classifying low-contrast ground targets in natural clutter environments. One target material of special interest is CARC paint, which is currently applied to U.S. Army vehicles in various colors to create woodland and desert camouflage patterns. CARC-painted test panels were observed in a wide variety of backgrounds and weather conditions during all of the JMSP experiments. It is shown here that certain fine-scale spectral features of this paint can support reliable two-color discrimination of CARC-coated test panels in different natural backgrounds, even under low contrast and high clutter conditions. The paper also examines environmental variations in two key parameters that determine spectral detectability; specifically, the observed target-background spectral contrast signature (which provides the required coloring), and the background spectral correlation (which provides for multiband clutter suppression).
