Low Cost, LPI, All Weather, Automated Optical Microwave Technology for IFF of Unmanned Aerial Vechicles (UAV)

RGI proposes to demonstrate through analysis the feasibility of using modified versions of the proven OMAR (Optical Microwave Approach and Ranging) technology to enhance the reliability and survivability of UAV's by using the OMAR technology for UAV, IFF, tracking and flight commands for evasive action when necessary. OMAR, currently under development as a low cost, stand alone, precision, all weather landing system for VTOL aircraft lends itself uniquely to these UAV requirements. Modifications to the exiting OMAR design will be required for this specialized UAV use but basic concepts of Luneberg lens beam shaping with angel/range processing will remain valid. Basic OMAR characteristics, including the ability to operate in a passive (covert) mode, makes it attractive as a portable 3-dimensional military IFF, positioning, tracking and command system with many commercial applications. For UAV applications, its response to authentication coded interrogation, structured in directional low-power reflective needle beams, provides a low probability of intercept and a positive identification of friend or foe (IFF) for unsophisticated, lethal and unmanned aerial vehicles. It's small, all, weather, unique operational characteristics makes it possible for OMAR to monitor more than 50 IFF targets and provide its 3-dimensional positioning information in digital form into intel networks such as the NOMAD and SAMURAI systems and/or Patriot Missile System in real time.
