As drones have become more popular among so many different user groups, they have become more affordable and the barriers to access have become lower. The nation's advances in sensors and weapons payloads have also been transferred to these user groups, technologies that are not as sophisticated but, when paired with the right weapons, can have lethal effects on a massive scale

　　Drones are now considered to be versatile, secretive and cheap airborne weapons that terrorists, criminals, fanatics and other dangerous people have never possessed, which poses a great threat to security and defense around the world, then in this situation, drone countermeasures are particularly important, the following Clairyeye Aviation to explain.

　　Drone countermeasures are divided into two main areas: first, detection and tracking systems, and then interception. The former includes radar, radio frequency (RF), electro-optical (EO), infrared (IR), acoustic and combined sensors. The latter includes radio frequency (RF) and GNSS(Global Navigation satellite Systems, including GPS and GLONASS) jamming, spoofing, lasers, physical network wrapping around targets, projectiles, electromagnetic pulses, and combinations of the above.

　　But it must be admitted that there is no perfect detection method for drone countermeasures. Many affordable electro-optic sensors are limited to daylight operation and direct line of sight to the target, and this is also true for infrared (IR) and many radio frequency (RF) systems. Rf and acoustic sensors use databases of known sounds and frequencies to detect drones, but the rapid development of new unmanned platforms prevents these databases from being fully updated. The sensitivity of the sensor is also an issue: too much sensitivity can produce many false positives, while reduced sensitivity can lead to missed positives.

　　A system that uses combined data from multiple sensors must also be able to distinguish between legitimate and malicious drones (IFF), which, unfortunately, is not something any known system can do at the moment. This is where a human operator needs to intervene as necessary, which is often a minute-by-minute assessment. On the other hand, the interception method also has its potential negative results, and electronic warfare countermeasures can easily affect civilians.

　　Where to buy drones and drone countermeasure equipment? Nanjing Clairyland Aviation, which is located in the ancient capital of the six dynasties Nanjing City, a manufacturer focusing on industrial drones and drone control system development for many years, can provide customers with including, inspection, aerial survey, environmental protection, plant protection, police, drone detection, drone countermeasures, and other industries to use the UAV, you can directly contact Nanjing Clairyland customer service.
