What are the methods of drone detection?

Anti-drone system development so far, the detection system is also gradually formed mature, just understand the anti-drone friends may question, anti-drone used to counteract drones, that can not detect drones? The answer is that it can be detected. The detection system in the anti-drone detection and defence system is mainly divided into radar detection system, photoelectric detection system and radio detection system.

The radar detection system is roughly divided into electric scanning radar, machine scanning radar, phased array radar. Electricity sweep radar in terms of price is considered more expensive, one side may be tens of millions of dollars, budget less friends can not consider; machine sweep radar is left and right sweep, 6s a circle, the radar needs to be scanned to the object 3 times to determine, that is, 6 × 3 = 18s to determine the object in the detection of the detection of some unmanned aerial vehicles may have a chance to take advantage of; phased array radar has 4 to 5 faces, face to face angle of 90 °, 1.5 Seconds to determine a point, equivalent to 1.5 × 3 = 4.5s to determine the object, so that the drone does not have any opportunity to take advantage of, is currently on the market all the anti-drone radar used the most.

Photoelectric detection system is a set of tracking system, when the radio and radar found the drone after the tracking lock, to jamming strikes to provide positioning. Optical detection systems are mainly visible light surveillance, infrared thermal sensors, and infrared laser surveillance technologies. Visible light surveillance (colour, black and white): used for daytime or daylight target detection, verification and tracking. Infrared thermal sensors: can be applied to detect infrared rays emitted to a target and identify UAV targets in the complete absence of light or in low light conditions. Infrared Laser Surveillance Technology: Used in nighttime glare conditions to improve target surveillance resolution.

Radio detection system is a more advanced and well-used approach. At present, the UAV radio bands are 1.5G, 2.4G and 5.8G bands, and the radio detection system detects the lateral sub-system for automatic search, discovery, identification and lateralisation of illegal invasion of UAVs. The radio detection system detects the presence or absence of UAVs through the frequency bands, so even if it encounters complicated terrains and obstacles blocking the UAV, as long as the UAV sends out the corresponding frequency bands, it can be be detected.

SOBO Group has rich experience and technology accumulation in the field of drone detection, mainly adopting the technology of radio detection to detect drones, which has been well verified and trusted by customers through years of use.
