Do you know the principle of the anti-drone system?

With the development of science and technology, military competition in various countries around the world has become more intense. The development of the field of unmanned aerial vehicles has also promoted the development of science and technology, and at the same time it has also brought security risks to society. Therefore, the anti-DRONE technology has been developed.Nuoanyue Technology anti-drone launched a low-altitude slow-speed small target defense system AUAV.

Most consumer drones rely on GPS and radio links for navigation, and interference or hacking is an elegant solution.Their communication protocol is relatively simple and there is no encryption.Cut off the link, the drone will automatically initiate the landing procedure as a security measure.

This is the operating principle of the so-called “anti-drone”: point the gun at the drone and send a powerful signal at common frequencies such as 2.4GHz and 5.8GHz.In the case of being blinded by a gun, the drone will think that it has lost the connection of the pilot and begin to return to its home.Add a GPS jammer to the mix and the drone will lose its position, drift or land immediately according to its emergency protocol.Simply put, the anti-drone gun is just a (overpriced) multi-band radio transmitter equipped with a high-gain directional antenna.

Drones are made of low reflectance materials.The challenge of radar drone detection lies in selectivity and sensitivity.Reduce the sensitivity of the radar.Fortunately, computer algorithms can distinguish threats by analyzing the patterns of flight trajectories.

Nuoanyue Technology's low-altitude slow-speed small target defense system is divided into: AUAV-portable, AUAV-fixed, and AUAV-vehicle-mounted.These three types of systems are simple to operate, can be quickly deployed, can be operated by a single person, and the equipment has a built-in large-capacity battery.The acting distance is more than 1.2 kilometers.Once the equipment is turned on, the remote control of the drone can fail, the captured images and videos cannot be returned, the GNSS navigation system loses the signal, and the contact between the drone and the remote control and even the ground end is completely cut off, so as to ensure that some important information is not leaked and avoid DRONE intrusion accidents in important facilities.
