ANTI-UAV

Civil unmanned aerial vehicle (UAV) is growing rapidly in a wide range of consumer communications and networks with their autonomy, flexibility, and a broad range of application domains. UAV applications offer possible civil and public domain applications in which single or multiple UAVs may be used. Nevertheless, we should also be aware of the potential threat to our lives caused by UAV intrusion, since UAVs can also be used to conduct physical attacks (e.g., via explosives) and cyber-attacks (e.g., hacking a critical infrastructure). Moreover, unauthorized UAVs are a danger to civilian aircraft. There have been multiple instances of drone sightings halted air traffic at airports, leading to significant economic losses for airlines... Historically, radar is certainly a very powerful technology for detecting traditional incoming airborne threats. However, these comparatively small drones are difficult for radar to accurately detect, because they have very small radar cross-sections..
