Anti-drone

1.

Detection technology

Active detection: radar (CORVS system) and laser scanning;

Passive detection: RF signal analysis, acoustic sensors, infrared for identification;

Hybrid detection: multisensor data fusion (such as dedronetracker).

2.

Reverse technology

Soft kill: GPS spoofing (such as AUDS), communications interception and network attack.

Hard to kill: laser weapons (helws), microwave weapons (thor's hammer) and physical interceptors (skywall);

Cooperative defense: a group of drones against (drone'intermediate').
