Droneshield

Counter-drone technology is based on detecting and subsequently neutralizing drones through hard and soft kill options. Short-range radar, electro-optical (EO), infrared (IR), and acoustic detection systems can detect small, low-speed, low-flying UAVs. Radars can provide non-cooperative detection capabilities without active support from the target UAV. Radiofrequency (RF) systems provide relatively short-range detection but are only effective when drones transmit RF signals. EO and IR systems are passive detection systems that provide visual detection day and night, respectively but have a shorter range than RF and radar systems. EO/IR sensors assist in re-verifying threats (secondary verification), followed by endpoint tracking and initiation of remediation. Finally, acoustic systems detect small drones at close range using acoustic signatures. Still, they are effective when no colliding noise is nearby and rogue aircraft noise profiles are recorded in the detection system library. Un...

  RF jammers are moderately expensive, provide non-destructive neutralization, have a short range, can affect or block other radio communications, teleport drones to targets, etc., and can cause unpredictable drone behaviour. They can cause significant unwanted effects, such as interference with television broadcasts, telecommunications, and air traffic control systems. GPS spoiler The controller uses GPS satellites to direct the drone. Fake GPS signals are used to mask communications with satellites, preventing the drone from moving as the controller intended. Drones can be "tricked" into thinking they are somewhere else, lose control of the auto-home function, and be hijacked and redirected to their intended area. Drone hijacking is an ideal approach and an easy-to-follow investigation. Geo-fencing A geofence is a dynamically generated virtual boundary of a natural geographic area that can lie within a radius around the location of a predefined point or set of boundaries. G...
