Advanced Radar Sensor Technology
Abstract
(U) The Advanced Radar Sensor Technology thrust develops radar systems to provide significant improvements in our ability to detect, identify, and track surface targets and threats over very wide areas in all climatic conditions. Program efforts focus on exploiting emergent and novel RF sensing technology and phenomenology. Key elements are advancements in ultra-wide band, bistatics, UHF/VHF, emitter location and direction-finding, polarimetric change detection, tomographic imaging, space-time adaptive processing and other advanced signal processing, advanced Ground Moving Target Indicator (GMTI) techniques, and foliage, building, and ground-penetrating radar phenomenology. Program developments are integrated with current and emerging military platforms, including small and micro UAVs, with emphasis on the most stressing military radar sensor challenges. Examples are operations featuring complex cluttered ground environments; those against small and slow moving surface targets; urban operations, and situations where camouflage, decoys and countermeasures must be overcome. Programs in this thrust include: • The Next Generation RF Antenna System program will develop and demonstrate a light-weight wide-band RF antenna that enables high gain over a broad frequency range and signal detection at extended ranges. This program is planned for transition to the U.S. Air Force. • The Airborne Passive Direction Finding with a Tactical Vector Sensor (ATVS) program will develop and demonstrate a compact, lightweight, airborne, real-time, tactical emitter detection and location system suitable for tactical UAVs. This program is planned for transition to the U.S. Army. • The Efficient Digitization of Element Signals program will exploit new and emerging techniques in signal coding and compressive sensing to allow large, element-count, radio frequency (RF) arrays to be digitally sampled using small numbers of receivers. Technologies are planned for transition to the Navy, Army and Air Force.
