Drone jammer is an electronic jamming method specifically designed for communication and navigation systems of unmanned aerial vehicles (UAVs). It aims to block or deceive drone remote control signals, GPS navigation signals, and other wireless communication links by transmitting signals of specific frequencies.With the development of drone interference technology, control interference, navigation failure, or forced landing of drones have now been achieved.

This technology typically includes the following key components:

1. Signal source: Generate interference signals of the same or similar frequency as the drone communication system.
2. Power amplifier: Enhance the power of interference signals to ensure they can cover the receiving range of drones.
3. Directional antenna: Concentrate the interference signal to a specific direction of the drone to improve interference efficiency.
4. Control system: used to adjust the parameters of interference signals to adapt to different interference scenarios and drone models.

Drone interference technology can be divided into several types:

1. Remote control interference: Directly blocking the communication link between the drone and the remote control. Make it impossible for pilots to control drones.
2. GPS interference: Sending false GPS signals, rendering the navigation system ineffective and causing it to lose its direction.
3. Multimodal interference: Simultaneously interfering with multiple communication systems of unmanned aerial vehicles to improve the success rate of interference.

Drone interference technology has been applied in both military and civilian fields. In the military field, it can serve as an anti drone (C-UAS) measure to prevent enemy drones from carrying out reconnaissance, strike and other tasks. In the civilian field, it can be used to protect sensitive areas and prevent drones from illegally entering.

However, the use of drone jammers has also raised a series of legal and ethical issues, especially in the civilian field. Due to interference, it may affect legal wireless communication in the surrounding area and even pose a threat to the personal safety of drone operators. Therefore, please comply with relevant regulations before use and ensure that it is used within the legal scope.
