During this period of time, everyone knows that drone flight incidents frequently occur, small enough to be used for peeping, large enough to steal state secrets and military secrets, small enough to fall and injure a person, large enough to cause the airport to close. The delay of the aircraft and the stranded passengers have caused serious consequences; therefore, the national laws have also been continuously improved during this period, and legal documents have been issued one by one to strengthen the control of drones and real-name registration; here we do not make any comments on politics, only Analysis of UAV defense and UAV countermeasures technology;
There are several ways to control drones:
1. This method of shooting with a gun seems to be more enjoyable. It is not only controlled but also destroyed. The damage index is higher by five stars. However, there is a problem that requires the shooter to be accurate. It is not the one who has participated in the Olympic Games and won the championship. Forget it, so as not to be embarrassed. In addition, you need to find the right time. Once you fall, it is absolutely not allowed to hurt people. It is very important to disconnect the phone. In addition, you must remember where you are calling. If you fall, you need to find it. This is a headache. The question, how many people do you need? Who flew the last question is unknown!
2. Catching with a net is similar to shooting a gun, except that the gun shoots out a point, here is a net; it seems that this technology has improved, the destructive power is reduced, and the accuracy rate is improved, but the prerequisite for the problem is The drone needs to fly low, and the human station is high, so the practicability is low;
3. UAV interference is also the mainstream technology at present. The remote control signal of UAV is blocked by high-power transmission, so that the UAV loses control. Generally, UAVs can be shot down directly, and smart UAVs can also be unmanned. Aircraft interference interferes with GPS and Beidou signals to prevent drones from returning home;
There are two types of UAV interference:
1). Hand-held UAV jammers require humans to conduct investigations, and it is found that manual intervention by hand-held UAV jammers can achieve the control effect; the control distance can generally reach about 2 kilometers;
2), base station type UAV jammer The base station type UAV jammer is mainly aimed at the relatively large control area, prevents the drone from entering the control area, and greatly reduces the safety risk; it can be completed without a large number of personnel operation; control Distance: 6-8 kilometers are ok；drone jammer for sale.
