A drone defense system is a security technology used to detect, track and block unauthorized or malicious use of drones. Such systems typically use radar, optical sensors, and other sensors to detect drones, software to track their flight paths, and techniques such as radio interference, electromagnetic interference, and laser positioning to block the drone's flight or track its controller. Drone defense systems are widely used to protect important places such as military bases, government buildings, important facilities, and event venues.

　　The UAV countermeasure system scheme can be combined with various technical means according to actual needs. Several common schemes are listed below:

　　1. Radar jamming technology: The use of radar countermeasures to send powerful electromagnetic signals to the UAV to interfere with its radar system, so as to achieve the effect of impacting its communication, navigation and control systems.

　　2. Photoelectric interference technology: The countermeasure device based on photoelectric technology can interfere with the visual perception of the UAV by generating a large amount of photoelectric smoke, thus affecting its attitude control and flight stability.

　　3. Infrared countermeasures technology: The use of infrared jammers to interfere with the infrared detection and navigation equipment of the UAV, so that it loses the infrared information basis, and cannot normally navigate and control.

　　4. Electromagnetic interference technology: Electromagnetic interference devices based on electromagnetic wave technology can interfere with the complex electromagnetic control system of the UAV by generating a large number of noise signals, cutting off its wireless communication signals to prevent it from receiving and sending instructions.

　　5. Ballistic strike technology: The use of ballistic missiles or projectiles to strike drones, so as to effectively strike drones of different volume levels to achieve the effect of damage or damage.

　　It should be noted that the scheme of UAV countermeasure technology is not a single technical method, and it is necessary to use a combination of various technical means and schemes according to the actual situation to fully implement the task of UAV countermeasure.
