Enhanced passive coherent location techniques to track and identify UAVS, UCAVS, MAVS, and other objects

摘要

A system and technique is described which has the capability to track and identify, in real time, various aircraft (100) and objects including Unmanned Aerial Vehicles (UAVs), Unmanned Combat Aerial Vehicles (UCAVs), and Micro Aerial Vehicles (MAVs). The system uses a combination of techniques including conventional automatic dependent surveillance broadcast (ADS-B) (110, 150, 200), transponder multilateration, broadband emitter multilateration, primary and secondary radar, and passive coherent location (400, 450, 500). A series of enhancement to conventional passive coherent location are described.
