There are many kinds of UAV counter-defense systems, each of which has its own advantages and disadvantages, and it needs to be scientifically selected and integrated for different situations in order to better realize the control and defense of UAS. Uav counter-defense system, through detection, tracking, jamming, interception and other ways to defend and destroy drones.
1. active jamming system: by transmitting electronic signals to interfere with the signal of the UAV, thereby affecting its navigation, communication and other functions. Generally, it includes three parts: electronic interference module, computer control module and signal transmission module. According to the situation, the signal frequency and modulation mode of the enemy UAV can be judged by the detection equipment and information processing system, and the corresponding electronic interference signal can be issued according to this, and the signal of the UAV can be interfered with, suppressed or even paralyzed.
2. Infrared interference system: Based on infrared light, it interferes with the guidance head, rangefinder, sight finder and other equipment of the UAV, thus affecting the navigation and aiming function of the UAV, and then making the UAV unable to complete the task. It generally includes three parts: optical component, electronic sensor and transmitter. For example, for the infrared signal transmitted by the enemy UAV, the infrared jamming system can affect the UAV detection and interception by transmitting the jamming beam or transmitting the jamming signal.
3. photoelectric detection system: through photoelectric sensing technology, the UAV flight path tracking, detection and identification of a device. It mainly includes photoelectric sensor, image processor and computer display three parts. The photoelectric detection system has the characteristics of high precision, high sensitivity, high speed and remote sensing. For example, the photoelectric detection system can detect the flight path of the drone and send the information of the drone to the operator, thus realizing the inspection and control of the drone
4. energy weapon system: by shooting powerful electromagnetic waves or laser beams to destroy or crash enemy drones equipment. It generally includes energy source, fire control unit and radiation unit. For example, by shining a laser beam, an energy weapon system can cause damage to the electronic equipment on a drone, so that it can no longer fly.
