ASD's FieldSpec 4 line of spectroradiometers is a critical tool for measurement and signature intelligence (MASINT). Accurate MASINT provides a strategic advantage in the planning of military operations and deployments. The successful exploitation of hyperspectral and multispectral imaging sensors depends on the availability of accurate and complete spectral signature libraries. Coupled with the appropriate spectral signature library, images collected with these imaging sensors provide the means to survey large areas identifying and characterizing materials, detecting a wide range of camouflaged targets, and detecting disturbed surfaces. Applications include remote evaluation of trafficability; shallow water bathymetry; and, camouflage characterization and detection.
