U.S. and China's anti-drone measures

  • For several years, the U.S. military has been developing various anti-UAV measures, including signal jamming or blocking, radar detection, and conventional counterattacks against aircraft.

    What is a drone jammer gun?
    The device has certain configurations and is a fully integrated rifle countermeasure that can be used with a variety of UAV models. Although it looks like the most powerful electron gun you have ever seen, it is actually a high-power jammer device that can interrupt multiple frequency bands at the same time.

    Geoffrey Kavada, deputy director of the Information Warfare Integration Department at the Marine Corps Headquarters, said: "If you just stay motionless on a part of the spectrum, they will certainly attack you and get into trouble." He said, Marine Corps Capability Development Commander unit. "But if you can manipulate the spectrum and feel and can manipulate the clean part of the spectrum, that's all we are doing...to be able to have dynamic spectrum access...we know we will be in trouble because we are dealing with them this way."

    drone signal jammer

    China, October 29, 2017-Unmanned aerial vehicles (UAV) or drones can generate various types of threats and interfere with personal privacy. This is why many people often seek effective drone jamming solutions to live a peaceful and safe life. Perfectjammer Technology Company, headquartered in China, has innovative interference with drones and wireless communications, which can protect people from these aerial equipment. Recently, they have developed long-range drone jammer, which can be used to hit devices from effective distances up to 1,000 meters.

    That is how the matter. First, the radar identifies and tracks the flying drone. Then, once the drone enters the camera range, the photoelectric camera will follow the drone to keep it focused. In the end, the jamming device attacked it: three antennas sent radio frequency signals to the target drone in an attempt to disconnect it from the original controller. Within a few seconds, the stuck drone stopped in mid-air and then fell to the ground.

    The vulnerabilities of GPS to blocking and phishing have been known since the beginning of technologies. While the reports on the threat from adversaries implementing GPS jamming technology have mainly focused on Russia, one of many countries developing GPS jamming and anti-spoofing technology.

    The GPS jammer works by sending its own signal on the same frequency as the GPS unit, a noisy signal that prevents it from receiving or transmitting useful information, either in bursts of sound or in a continuous wave.
