In theory, you could classify the devices here into the drone detection and drone disruption categories. The former is concerned with identification, while the latter is more concerned with deactivating detected drones.

UAV monitoring equipment
There is a lot in the surveillance equipment category. First, there are RF analyzers that use antennas and processors to receive and analyze radio waves using the spectrum. In most cases, this provides the brand and model identification. More advanced RF analyzers can even provide drone and controller triangulation.

Microphone arrays can also be used to detect drone sounds and provide direction calculations. Of course, the effect starts to drop in noisier environments.

Optical sensors come down to cameras and can use infrared or thermal imaging. Of course, while they can help identify drones and their payloads, false-positive detections and poor performance in low-visibility conditions are to be expected.

Radar cannot be ignored here, it is used to detect the position and orientation of the drone by sending out a signal and listening for reflections. As mentioned, these are almost exclusively used to track larger objects.

Drone jammer,this is a countermeasure that sends uncontrollable frequency-based energy behind the drone, preventing the controller signal from reaching the device. When this happens, the drone may land, return home, fall to the ground, or take off in a random direction.
The effect depends on the manufacturer. Note that this is a short-range countermeasure and cannot accurately measure the impact this technology will have on drones.

Anti-drone gun
The anti-drone gun is exactly what it sounds like. These are for shooting drones. In this case, the lenses could be physically destructive, or they could provide a burst of radio frequency signaling technology.
Jammer mart sells a wide range of drone jammers, a variety of power and different types of drone counter guns for you to choose from. Our drone jammers come with a high-definition telescope configuration to help you aim quickly. Welcome to consult and understand.

Consumer drones have become a growing threat to global military power, and drone jammer has received a lot of attention in recent years. In 2019, the Pentagon announced that the U.S. military now has the full legal right to shoot down commercial or private drones it sees as a threat.

Since then, many local communities have been told that any UAS (unmanned aircraft system) entering military airspace could be destroyed or seized.

How do terrorists use drones?
ISIS forces in Iraq and Syria have repeatedly used drones modified with grenades to provide makeshift booby traps or destroy armored vehicles from above.

Even unarmed, the surveillance capabilities of most commercial drones can pose a significant threat to military personnel or facilities.

It allows opponents to gain footage in hopes of planning future attacks. More worryingly, the technology is rapidly miniaturizing, meaning drones are getting smaller and more agile.

Let's talk more about how to safely locate and disable drones within your facility.

Locate the drone
Various technologies are used to identify drones entering restricted areas, and these devices come in various configurations. Blocking and disabling drones is done through similar techniques used in cellular GSM jamming.

Once the drone is located, the military can take action to safely disable the device to prevent harm to civilians. By knowing where the drone system is, the team can disperse the drone or shut it down.

Disable drones
Some weapons fire a net that traps and adds weight to the drone, then shoots it down with a parachute.

While the range is short, the benefit of this approach is that the aircraft can be seized for forensic testing in hopes of finding vital intelligence.

Assets and military installations are not always isolated, which can pose a threat to the public. In most cases, there is a significant risk of destroying drones when someone is nearby, especially if these drones are loaded with hazardous materials or explosives.

Drone jammers work by jamming the controller's RF directional signals and allowing military personnel to gain access to the drone system. Such technologies are often used to protect stadiums in the event of a major incident where terrorists could pose a potential threat.

Directed energy is also an option, but still experimental. It has its limitations and disadvantages, including limiting how far the lens can travel. "That's probably only going to be used in military vehicles for the next five to eight years," said Col. John Hayscock, director of the U.S. Army Fire Laboratory.

Jammer mart drone gun jammer can block all drone communication frequencies, including GPS and WIFI. It interferes with GPS communication systems such as UAV WIFI and GPS-L1 by transmitting radio frequency signals. The drone anti-gun with a high-definition telescope can help you quickly lock on the target.

 

When these signals are blocked, the unauthorized drone is neutralized and begins to descend to the ground, where it can be retrieved. The unit can jam all frequencies together for at least 6 operations of 10 minutes each.

Drones can pose risks to human health and safety. They are also frequently used to monitor and obtain vulnerable information from protected areas, such as military bases, and cause casualties through explosives. Therefore, the field of drone jammer is developing rapidly, especially in the military field.

Nets
The military often uses this drone detection solution to capture drones. When the net hits the drone, it stops it and makes it fall to the ground. Thanks to this, it is easy to prevent the drone from returning to the sender and prevent vulnerable information from leaving the military station, or worse, prevent physical damage from explosives carried by the drone.
Pros: When the drone is physically captured, there is very little risk of returning to the sender or causing casualties in the event of an explosion. Additionally, using the web can help find and prosecute senders. Ground-launched net cannons are highly accurate.
Disadvantages: The reloading time of the drone network is long, so if there is more than one drone, or if it is not caught at the first time, the threat still exists.

Radar
Radar uses radio energy to locate objects. With the help of radar, the orientation and position of the drone can be measured. Most radars send radio signals and "listen" for the echoes. However, they rarely choose small goals. Radar is designed to track larger objects such as airliners. However, the military also uses radar to locate small drones that may be in the area.

Four Major Anti-UAV Technologies - Radar Advantages: Radar helps to cover wide terrain. They provide accurate positions and can locate multiple targets simultaneously. Because the defense has to be as strict as possible

Radar is a great solution regardless of the weather, even in poor visibility conditions like fog, night, etc.

Cons: Most radars cannot distinguish between small drones and small flying animals like bats or birds. Therefore, radars may not be efficient enough for the military, as they may miss small drones.

High Power Microwave (HPM)
High-power microwave equipment can damage other electronic equipment, such as drones. HPM may interfere with the radio link for manipulating the drone. Due to the high voltage and current of the HPM, the HPM usually destroys the drone. Thanks to this, dangerous situations can be avoided, for example, when a suspicious drone enters a nearby area.

Pros: Effectively deter drones within HPM range.

Cons: While this technology can protect military bases and high-security areas, it can compromise other electronic devices and even destroy them accidentally and unintentionally. In addition, HPM can interfere with communication signals

GPS Spoofer
Thanks to this technology, a signal is sent to the suspiciously detected drone and misleads its whereabouts. Since GPS coordinates are dynamically alerted, a spoofer can take control of the drone. In this way, equipment can be moved from the area to a "safe zone", reducing the risk posed by the presence of drones.

Pros: GPS spoofers are one of the most affordable technologies. As an effect, they can be purchased in bulk by the military and used in various places.
Cons: Unfortunately, there is a risk of interfering with other radio communication signals.
The drone jammer can detect the presence of drones at a distance of about 3 kilometers and MUAVs at a distance of 20 kilometers, depending on the environmental conditions and the flying altitude of the drone. This provides accurate situational awareness and time to react to threats.

- Passive RF sensors scan the area for electromagnetic signals that can be identified as drone communications. When a threat is identified as a drone, the direction of arrival is clearly shown to the system operator to take action. By installing several RF sensors, the detection range can be extended, and through triangulation, the location of the drone can be precisely determined.

If the hum of an overhead drone still freaks you out, get used to it! The use of drones has expanded into all walks of life (entertainment, science, agriculture, journalism, medicine, military, logistics, etc.) and inevitably to the darker side as well. Criminal and terrorist groups have discovered the versatility of drones, and they now routinely deploy them as a sort of small air force for surveillance, delivery of illicit cargo, or full-scale attacks. Rogue drones, individually or in groups, pose a threat that every law enforcement, security advisor and defense agency must consider. One of the first countermeasures developed against drones was the drone jammer, which targeted the communication channel between the drone and its operator. Fixed area solutions as well as mobile handheld transmitters are readily available to protect valuable assets from drone threats that can cause all kinds of damage. While this is a relatively low-cost solution, its simplicity may limit its usefulness.

Limitations of Interference
A drone is small, a small point in the vast airspace surrounding any target, be it a person or facility, stationary or mobile. For example, in order to protect an airport from drone threats by interfering with its radio frequency communications, it is necessary to detect the presence of drones, identify the communication frequency and jam it within a certain distance to eliminate the threat. These variables enable targeted Jamming becomes an unreliable solution because it takes some time to lock and analyze the signal, and frequency switching is common. On the other hand, broad defenses such as total jamming can lead to many unforeseen situations, since RF signals have a very wide range of civilian uses (the most important of which is air traffic control).

Additionally, since RF signals are susceptible to random interference, the drone industry is evolving to address this vulnerability by securing communication channels (necessary for securing even the most casual day-to-day operations, such as delivering packages to the correct address) . While alternative guidance methods, such as GPS positioning, can create a "dark" drone that can accomplish its mission independently of any further instruction/communication with the operator.

While drone signal jammers are undoubtedly the most common method of jamming and defending against rogue drones, it is clear that as drones become more widely used and their technology more sophisticated, countermeasures against them Will need to keep up.
