With the rapid development of UAV technology, UAV is increasingly widely used in various fields, including commercial shooting, agricultural monitoring, emergency rescue and so on. However, the popularity of drone technology has also brought a series of safety hazards and potential threats, especially in low-altitude areas. Therefore, counter-drone technology has become a key force to protect low-altitude safety. Low-flying drones can counter interference in a number of ways.
Jamming drone signals: By jamming a drone's radio frequency signal, to prevent it from communicating with ground control, is a common countermeasure. This method will not destroy or damage the UAV, but can effectively drive away or force down the UAV, to ensure the safety of the airspace in the area.
Using the drone counter gun: the drone counter gun interrupts the flight control system and signal transmission system of the drone, to drive away or make a forced landing. This technique is relatively mild, can be quickly and accurately achieve the effect.
Laser air defense system: using laser good directionality, high intensity of illumination of the properties, to transmit high power laser distance, projected onto the target, by ablation surface material of unmanned aerial vehicle (uav), features, to undermine its dynamic characteristics, , to energy system, flight control system, etc., making targets had been destroyed or incapacitated.
Full-band jamming equipment: full-band jamming equipment has flexible frequency band selection and switching functions, to adapt to different UAS working frequency bands. generates interference signals through the generation of analog or digital signals, blocks the communication and navigation links of the UAV, and makes it lose stable flight ability.
Acoustic interference: interferes with the gyroscope used to maintain the flight stability of the UAV through sound waves, affects the stable flight of the UAV.
Electronic countermeasure technology: By using electronic countermeasure technology, by receiving, sorting and analyzing UAV remote control signals and image transmission signals, accurately identify the intruding UAV, and block the communication link of UAV by repressive electromagnetic interference.
These technical means can be applied in a wide range of to meet the requirements of different occasions, is especially suitable for the need for rapid deployment, such as large venues, infantry troops and so on.
