Abstract
Systems and methods relating to the use of one type of radar technology to accomplish the function of another type of radar technology. Secondary Surveillance Radar/Identification Friend or Foe (SSR/IFF) technology can be used as if it was Primary Surveillance Radar (PSR) to gain the advantages of both systems. Radar signals useful for SSR/IFF are used as PSR signals. Reflections of the SSR/IFF signal off of both airborne and ground based aircraft, and ground based vehicles and items are used to locate and identify these aircraft, vehicles and items. For SSR/IFF transponder equipped aircraft, the reflected SSR/IFF signals provide (prove dial) dual confirmation of the aircraft's presence while for non-transponder equipped aircraft, the reflected signals provide an indication of the aircraft's presence. The use of SSR/IFF signals reflected off of ground based vehicles and items provides an indication of ground based vehicles and items present around the installation receiving the reflected SSR/IFF signals.
