Unmanned aerial vehicles frequently occur. They are small enough to be used for voyeurism, large enough to steal state and military secrets, small enough to fall and injure a person, large enough to cause airport closures, aircraft delays, and passengers stranded. , Causing serious consequences;

Therefore, national laws are constantly improving, and legal documents are issued one by one to strengthen the control and real-name registration of drones;

Here we do not make any comments on politics, only analyze drone defense and drone countermeasures;

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 than five stars. However, there is a problem that is more headache. Forget it, so as not to be embarrassed. In addition, you need to find the right time. Once it falls, it is absolutely not allowed to hurt people. It is important to get off the phone. In addition, you must remember where you are calling. If it falls, you need to find it. This is a headache. How many people do you need? 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 UAVs need to fly lower and people stand higher, which is less practical;

3. UAV interference is also the mainstream technology at present. The remote control signal of UAV is blocked by high-power transmission, so that UAV loses control. Generally, UAV can be shot down directly, and smart UAV can also be unmanned. Aircraft interference interferes with GPS and Beidou signals to prevent drones from returning home.

1). Hand-held drone jammer require people to conduct investigations, and it is found that manual intervention by the handheld UAV jammers can achieve the control effect; the control distance can generally reach about 2 kilometers.

2) Distributed UAV jammers Distributed UAV jammers are mainly aimed at a relatively large control area, preventing drones from entering the control area, greatly reducing safety risks; it can be completed without a large number of personnel. ; Control distance: 6-8 kilometers can be;

3) Radar-based deployment jammers are a bit too tall. In order to build a drone, even radar is used. The cost can be imagined. The actual effect is actually no different from deployment-based drone jammers. But it is flying into the detection range of the radar, and then interfere. I don't know what the civilian radar technology is. Anyway, there is one more device and one more failure point. The main cost is really toothache;

In addition, I did a lot of searches on the Internet, and the Chinese characteristics are vividly reflected. As long as there is a need for thousands of troops to invest in this market, the market capacity and market opportunities are as big as everyone's guess;

One set to two sets for one unit, let’s calculate that the quantity is really limited and belongs to a niche market; in addition, the technical content is not particularly high, the threshold is low, the more participating merchants, the smaller the market profit margin, so it is recommended that those already on the road should be prepared Don’t get on the road for a while, look at the market sensibly.
