High-tech radar maps defeat camouflage: "To the untrained eye, U.S. Army radar-generated maps may look like a bird's-eye view of a city at night; however, these images contain useful intelligence, surveillance and reconnaissance information that reveal concealed objects by penetrating foliage, buildings and some terrain while overcoming camouflage, concealment and deception techniques.
These maps, which highlight boundaries not visible to traditional electronic sensors, are made possible by the U.S. Army's Tactical Reconnaissance and Counter Concealment Enabled Radar, or TRACER. Developed by the Research, Development and Engineering Command's communications and electronics center, TRACER is a mid-range, long wavelength synthetic aperture radar system that provides all-weather persistent surveillance."
