The important role of UAV jammers in future electronic warfare

The working frequency and signal strength of the UAV signal jammer are higher than the expected signal of the receiver. Therefore, if the jammer has sufficient power and a sufficiently wide signal spectrum, it may block all receivers in one base station. Another method is to jam the copy of the expected signal and trick the receiver into receiving the interfering signal instead of the expected signal.

The U.S. Army hopes that signal transmitters now installed on drones will dominate electronic warfare (EW) and is turning to a contracted transmitter that is poorly understood and not strictly regulated. According to four U.S. officials, the Russian military has been using GPS to intercept drone jammers to interfere with some U.S. military drones operating in the Syrian sky, which has seriously affected U.S. military operations.

A few weeks ago, the Russians began to interfere with some smaller American drones. Officials explained that the Russian military was worried that the US military would retaliate for the retaliation and began to block the GPS systems of drones operating in the area.

However, in another case, the wireless link is particularly vulnerable and is deliberately blocked. Here, someone deliberately uses a particularly effective attack against a specific link or link family to prevent the link’s communication capabilities. For malicious purposes, such as profit-making purposes, or to gain military advantage during wartime, you can try to block. The GPS agency of the US government is convinced that commercial aircraft “maintain alternative navigation methods” to prevent terrorist attacks. The agency said: “The government is currently sending new GPS signals, which are more resistant to interference.”

Drone jammers are becoming more advanced in electronic warfare

The Navy sent hundreds of electronic warfare experts to Iraq to lead the harsh sound in a harmonious manner with 14 types of jammers to allow the device to send its signal and then remain silent for a few milliseconds so that other devices can transmit; In this way, Warlock Red and Warlock Green can be packaged in a combined unit.

It is believed that North Koreans own old drone jammers purchased about ten years ago, as well as their own household equipment. These military jammers were placed on the hills of Kaesong province, near the border, to reach the maximum range, Rust said.

A new generation of military jamming equipment has also been introduced, which can cover a wide frequency range and perform specific “triggered” jamming, which means that “Duke did not mistake the receiver for a modified version of its own signal, a series of built-in Interference response is aimed at deceiving very specific equipment. “With the improvement of jammers, Iraqi insurgents basically abandoned the use of FDI, and the number of deaths from FDI declined.

The reason for the use of jamming equipment, a military switch called the radio-controlled improvised explosive device electronic warfare system (CREW), attempts to intercept or intercept the signal before it reaches its intended target to prevent an explosion. A common method is barrier interference, which can eliminate a wide range of radio signals. However, it also prevented the communications used by the US military. The United States, which exposes them to greater risks.

Interference involves pumping RF into the frequency range that they have enough to control their own signals. Therefore, you need a power supply and you need to know the frequency range. Because RF decreases with the square of the distance, unless you can aim very carefully, you must be close to or have a lot of power. They don’t really release the target you need to aim for, so they need a lot of features.

The tremendous role of drone jammers in electronic warfare

The first use of countermeasures against electronic interference can be traced back to the Second World War. Radar-controlled artillery shot down many enemy aircraft. These systems use radar signals to block and track air targets and command air defense firepower. When conducting critical joint operations, the Resistance placed the drone jammers near these weapons. The image in the news film shows how the shell randomly rotates and shoots randomly due to interference.

In electronic warfare, some officials said that the equipment used was developed by the Russian army and is very advanced, even for certain encrypted signals and anti-jamming receivers. So far, this drone is a small reconnaissance aircraft, unlike the large “predator” and “reaper”, they usually operate in a combat environment and can be armed.

Since the target may be moving, local Wi-Fi broadcasting is a more direct method. Here, when transmitting a signal in a specific frequency band, a higher power level than the initial signal can overwhelm the receiver and block communication. Four U.S. officials told NBC News that Moscow was worried that the United States would block the GPS systems of some small drones in order to retaliate against attacks on the eastern Guta area occupied by the rebels.

But sources told the National Broadcasting Corporation (NBC) that it turned out that the advanced UAV jamming equipment developed by the Russian army is effective even for certain encrypted signals and anti-jamming receivers.

UAV jammer equipment used in Nanshan Islands, China

China seems to be planning to use electronic attacks designed to damage or control U.S. drones. There are reports that China is attempting to interfere with U.S. drones. In recent years, the United States has at least once been willing to use drone jammers to prevent aircraft from taking off from the United States. The United States carries out surveillance missions in the Nansha Islands.

Murmansk-BN is the world’s most powerful long-range electronic warfare (EW) system developed by KRET, a subsidiary of Rostec Holding. The EW system is designed to disrupt radio communications within a maximum range of more than 3,000 kilometers (1,864 miles). The jammer is specially designed to solve high-frequency communication systems (including global high-frequency communication systems).

Some jammers launched at the beginning of the war, such as GPS jammers in vehicles, reported later updates aimed at overcoming various threat signals. Ryan explained that, for example, the in-vehicle gps interference radiation currently present in thousands of cars in theaters represents a technological capacity increase.

Electronic warfare jammers need to analyze a wide bandwidth with low signal-to-noise ratio (SNR) to detect critical and time-sensitive threats. One way to achieve this is to channelize a wide bandwidth through a filter bank and fast Fourier transform (FFT) to separate the signal of interest from noise and interference sources.

 

Drone jammer plays an important role in electronic warfare

It now appears that North Korea, determined to expel US troops from the Korean Peninsula, may have successfully hit this fatal weakness. Although the Pentagon denied the news, South Korean military reports believe that the concealed drone jammers on the North Korean hill is likely to cause an “emergency landing” of the US spy plane.

Sources say that Russian companies are also unlikely to be involved in providing Iraq with the most effective Russian equipment, such as an electronic jamming system that could damage the US air-to-air missile attack in Baghdad. However, the same source said that some Russian technicians who once worked for the Russian army may decide to go to Baghdad in their own name out of sympathy for the Iraqis.

In addition, the military has other systems that can minimize the impact of GPS signal interception on the bomb. A Boeing spokesman said that the joint direct attack ammunition combines GPS guidance kits and gravity bombs, as well as a separate inertial navigation system, which is used as the primary means of finding targets.

Remote control high-power military jammers are widely used in prisons, protection, surveillance and other fields. If you are looking for a powerful and effective office interference device, you can stop here. Just put the device in the shopping cart, if you use this kind of interference in the office, you can easily block the mobile phone signal in the office. Because it locks the entire phone, your employees will not have the right to disclose more information.

Drone jammer is enthusiastic by the government

With the emergence of unmanned aircraft (UAV), we can explore more unknown worlds. However, in recent years, with the development of drones, it is not entirely a good thing to carry it. Officials of the Federal Bureau of Investigation (FBI) recently revealed that criminal gangs organized using drone incidents have made hostage rescue difficult, which highlights the need to regulate drones (UAVs). ).

Law enforcement personnel use unmanned aerial vehicles (UAV) to monitor criminals. Some criminal organizations have been using drones to monitor witnesses: they continue to monitor police stations and jurisdictions to understand who is inside and outside the police station and who can cooperate with the police. Unmanned aerial vehicles (UAV) also play an important role in theft and other aspects. In addition to documented thefts, criminal gangs using drones are also looking for larger target facilities, discovering security vulnerabilities and routine procedures, such as where to go for security personnel. The powerful drone jammers can interfere with the drone flight, thereby greatly reducing the occurrence of various crimes.

In Australia, criminal gangs have begun using drones and plan to implement complex smuggling activities. These teams will supervise port personnel. If workers or smuggling containers near illegal goods stores, criminal gangs issue fires, robbery or other false alarms, they will attract security personnel.

U.S. Customs and Border Protection In the United States, Andrew Scharnweber, deputy director, described how cybercrime uses unmanned aerial vehicles (UAVs) to monitor border patrols, determine their vulnerability in coverage areas and Used. “Border patrol, our scouts are fighting people crossing the border. They are camping near the top of the mountain, and law enforcement personnel and radio let their associates surround us. Now these activities are he added that the criminal gang will use unmanned in the border Machine for drug trafficking.

Countries use wireless jammers to prevent foreign broadcasts

The wireless signal jammer sends electromagnetic waves at a certain frequency, and then the waves will be broadcast throughout the area. Radios will receive this wave (if it is set to that frequency), and they will block another wave broadcast by the station.

The (usually intentional) transmission of wireless signals can interfere with communication by reducing the signal-to-noise ratio. The other type is unwanted interference, which occurs when the operator transmits on the occupied frequency without first checking whether the frequency is used, or if the station using the frequency cannot be heard . This can also happen when the device accidentally transmits a signal (for example, a cable TV device that accidentally transmits on the emergency frequency of an aircraft). This concept can be used in wireless data networks to disrupt information flow. Some countries will use wireless wifi jammer to prevent foreign radio stations in border areas from reaching the country.
