During this period of time, everyone knows that drone black-flying incidents happen frequently, 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. Legal documents have been issued one by one to strengthen the control and real-name registration of drones. Here we do not make any comment on politics, only UAV defense and UAV countermeasures technical means are analyzed.
There are several ways to control drones:
1. This method of shooting with a gun seems to be more enjoyable. It not only manages but also destroys it. The damage index is higher than five stars. But there is a problem that is more headache. It requires the shooter to be accurate, not the one who has participated in the Olympics 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 important to get off 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 points, here is the 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. Drone jammer 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 the handheld 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 can be;
In addition, I did a lot of searches on the Internet. 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 per 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 businesses, the smaller the market profit margin, so it is recommended that those already on the road should be prepared Don’t be hot on the road for a while, look at the market sensibly.
