Loop technology (LOT) as an alternative surface surveillance system

This paper provides an overview and preliminary results for demonstration of a prototype distributed loop-based system called LOT. This paper contains only the understanding and views of the authors and is not intended to reflect the official position of the FAA. The FAA completed the first phase of a prototype system installation in 1997 at Long Beach Airport (LGB) in California. This prototype applies inductive loops, a mature technology, to the airport surface surveillance application. The project also involves a technology transfer of neural network signal processing technology from Department of Defense to form a non-cooperative surface movement sensor system. LOT has the potential to be used in a standalone mode or as a supplemental sensor input to an Airport Surface Detection Equipment (ASDE) radar surface surveillance system
