title: Tactical airborne reconnaissance goes dual-band and beyond
abstract: Multispectral imaging technologies are satisfying the need for a "persistent" look at the battlefield. We highlight the need to persistently monitor a battlefield to determine exactly who and what is there. For example, infrared imaging can be used to expose the fuel status of an aircraft on the runway. A daytime, visible-spectrum image of the same aircraft would offer information about external details, such as the plane's markings and paint scheme. A dual-band camera enables precision image registration by fusion and frequently yields more information than is possible by evaluating the images separately
