document: Tactical airborne reconnaissance goes dual-band and beyond 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
