Is the shooting down of a drone by electromagnetic waves to transmit energy

Hello, glad to answer for you. Unmanned aerial vehicle (UAV) (unmannedaerialvehicle or drone), UAV is a type of unmanned aerial vehicle that is controlled by a radio remote control device or its own programmed control device. From a technical point of view, the definition can be divided into:

Unmanned, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airships, unmanned paragliders. UAVs are widely used, low cost, and have a good cost-effectiveness ratio; No risk to personnel**; It has strong survivability, good maneuverability, and easy to use, and plays an extremely important role in modern warfare, and has broad prospects in the civilian field. UAVs are divided into reconnaissance aircraft and target aircraft.

In the military field: reconnaissance aircraft: can be used to complete battlefield reconnaissance and surveillance, positioning and calibration, damage assessment, electronic warfare, etc.; Target Machine:

It can be used as a target for artillery and missiles. In the military field, Western countries, led by the United States, have played a very good role in the use of UAVs. In the civilian sphere:

It can be used for map mapping, geological survey, disaster monitoring, meteorological detection, air traffic control, border patrol monitoring, communication relay, pesticide spraying, etc. Like Kunming Jinying UAV, it does a better job in aerial survey, aerial photography, flight services, remote sensing, etc. Hope mine can help you.

This possibility must exist, and it depends on the importance of electromagnetic interference and its suppression ability when designing the drone.

There are many flight control methods for UAVs, and the main ones currently used are wire control, wired electric remote control, radio remote control, program control, etc.

Wire control wire control is to use a hand-held steel wire to control the power of the drone, this method is mostly used in competitive model aircraft.

Wired remote control.

Wired remote control is a relatively simple and low-cost way to operate. The ground station personnel transmit various control signals to the drone through cables or optical cables to control its flight and work, and the drone sends the detected information back to the ground station through the cable. Its disadvantage is that due to the limitation of cable length and weight, the range and ceiling of the aircraft are not large, and the activity area and observation range are small.

Radio remote control.

When the radio remote control mode is adopted, the activity radius and flight freedom of the UAV are mainly limited by the transmission power of the airborne and ground remote control equipment, the transmission distance of radio waves, and the performance of the aircraft itself. Affected by factors such as the curvature of the earth and the transmission power of remote control equipment, the ground station generally has a short operating distance and can only be used for flight control at a relatively short distance (within 250 km). If a relay platform or satellite communication is used, it can also be operated over long distances or even at intercontinental ranges (tens of thousands of kilometers), but the cost will be greatly increased, and the use will be more complicated.

In addition, the use of radio remote control is susceptible to electromagnetic interference, in which case it is not only difficult to complete the mission, but may even cause the drone to not return.

Program-controlledThe so-called program-controlled means that the UAV relies on the airborne flight control system and the equipment on board to achieve flight control along the predetermined route according to the program. The airborne flight control system is mainly composed of an autopilot, a computer, a navigation system and various flight parameter sensors. During the flight, the system uses various sensors to obtain the direction, position, altitude, speed, overload, acceleration, angular displacement, angular velocity, angular acceleration and engine speed of the UAV in real time.

Compared with the radio remote control method, the range of activity of the drone with program control is larger. Its radius of activity is mainly affected by the performance of the aircraft itself. Some new UAVs are even capable of flying across oceans and can perform reconnaissance, surveillance and other tasks more than 5,000 kilometers away.

Its disadvantage is that in the cruising state, it generally flies according to a pre-selected trajectory, and even if it is discovered by the enemy, it cannot maneuver autonomously, and once its whereabouts are exposed, it is easy to be intercepted by the opponent. In order to overcome this shortcoming, some UAVs are controlled by a combination of pre-storage programs and remote control, or by sending commands to them to change the program through satellites.

Electromagnetic waves, different drones are equipped with different wireless devices, and the traffic supported by different frequencies is also different.

Optical transmission of information requires carriers, like fiber optic cables.

The electromagnetic radiation of the TT&C system adopts the electromagnetic radiation technology with low spectral density.

The uplink and downlink signals of the TT&C system are directly sequenced and spread-spectrum transmission, and some systems adopt a spread-spectrum hopping hybrid system, while the new chaotic spread-spectrum TT&C system has its unique performance in terms of information concealment, signal concealment, and anti-interference ability.

Through the ground-to-space line-of-sight data link, aircraft relay data link or aircraft-satellite-to-ground satellite relay data link, comprehensive functions such as mission planning, command and control, remote control, telemetry, tracking and positioning, and payload data transmission of various types of UAVs of different types and purposes can be realized.

Infrared infrared is electromagnetic waves with wavelengths between microwaves and visible light, with wavelengths between 1 mm and 760 nanometers (nm), which is longer than red light. Anything above absolute zero can produce infrared. Modern physics calls this a heat ray.

Medical infrared can be divided into two categories: near-infrared and far-infrared. Containing thermal energy, the heat of the sun is mainly transmitted to the earth through infrared rays.

From Sogou Encyclopedia.

How can it be so mysterious... A drone is a small plane... And because it is a remote pilot, its maneuverability and evasion ability are far less than that of ordinary aircraft...

Anti-aircraft artillery, missiles, can shoot down UAVs.

The jamming system with the Russian car plant led to the American GPS satellite navigation mistake and fell.

I haven't seen the Matrix, only one thing, electromagnetic waves. Anything that relies on electricity can get him out of trouble, and it's very simple and effective. If the antenna is broken, the aircraft will ** for a certain period of time, and it is enough to make good use of this time.

How many kilometers can the drone fly and how is it controlled? Today is a long time to see.

Generally a digital signal. The data transmitted is encrypted. It is said that many U.S. drones are unencrypted and can easily hack in.

The drone mentioned by the questioner refers to the drone used for aerial photography, and the answerer seriously answered the question.

Radio waves, first through satellites, are transmitted to radar stations.
