The most popular view of drone swarm warfare from

  • Detail

On September 14, two important oil facilities of Saudi Aramco were attacked, resulting in the shutdown of half of Saudi Arabia's oil production, affecting 5% of the world's daily crude oil production. Yemeni husai armed forces later claimed responsibility for this and claimed that they used 10 drones to attack the above facilities. Due to the large number of UAVs that may participate in this attack, some analysts have linked this attack with "drone swarm warfare". Is this attack a real drone swarm attack? How big is the threat of such an attack? How to deal with such attacks

either a large number or a "swarm"

in this attack, husai armed forces claimed to use 10 UAVs to attack, so some people linked it with "drone swarm attack". However, experts say that it is not really a drone swarm attack

experts said that UAV swarm attack should at least have the ability of collaborative interaction between platforms. Many UAVs can organize themselves and cooperate. Su Ming made a special report on new energy industry policy research through high-precision flight, keeping the posture and synchronization, and improving the organization, mobility and coordination of the unmanned system. At present, the research in this field in the United States is quite active. In 2016, the U.S. strategic capability office cooperated with the U.S. Naval Aviation Systems Command to test the drone swarm Technology: three f/a-18 fighter planes launched more than 100 "grey Partridge" micro UAVs at the "China Lake" naval aviation weapon station in California. The "grey Partridge" swarm UAVs were not pre programmed during collaboration, but formed an organic whole through distributed brain decisions, and could adapt to each other like bees

in November 2017, stratoenergetics, a UAV company, released the concept of a micro UAV weapon "stinger". According to the assumption, it is a miniature intelligent four intelligent UAV with a diameter of less than 10 cm and a warhead. It can automatically carry out face recognition through the equipped camera. Once the target is confirmed, the warhead is used to make the polishing damage layer shallow to "blow the head" of the target. During operation, the drones are released in large numbers to carry out swarm attack

in contrast, this attack is very different from the concept of swarm. I'm afraid these UAVs are just "swarming" to enhance the strike effect. It should be noted that the bee swarm UAV technology is still in the demonstration and verification stage. For example, the flight distance and speed of "stinger" are very limited, so it must be put near the target first, which is dangerous. Secondly, precise navigation is also a problem when there is no GPS signal when it is used to measure and record the signal voltage change indoors. Finally, the chip for face recognition may still need to be miniaturized. Of course, face recognition is not so easy

the increasingly prominent threat of drones

this drone attack has had a significant impact on Saudi Arabia's oil production. The Saudi government said that the country's crude oil supply has been reduced by 5.7 million barrels a day, accounting for about 50% of its oil production, which has aroused widespread concern. In recent years, similar drone attacks and drone intrusions into sensitive areas have emerged one after another, making the threat of small UAVs increasingly prominent

on August 4, 2018, Venezuelan President Maduro was attacked by a drone bomb while attending an army commemoration. In june2017, a falling UAV was found in a mountain forest in Gangwon Road, South Korea, near the military demarcation line between the two Koreas. At that time, the UAV had taken hundreds of photos. On january26,2015, a civilian UAV mistakenly landed at the White House. At that time, the four axis UAV about 60 cm took off from about 10 blocks away in the east of the White House, flew over the presidential residence and crashed on the lawn in the southeast of the White House. If these drones carried bombs at that time, I'm afraid it would cause a greater sensation. In addition, on the Syrian battlefield, Syrian opposition forces also frequently use small UAVs to sneak attacks on Syrian government forces and Russian bases. However, most of the attacks against Russian bases were thwarted by Russian air defense systems

experts said that most of the above UAVs have low technical content. They are either based on the modification of consumer grade rotary wing UAVs or adopt "aircraft model" technology, which is easy to manufacture or obtain. Although previous attacks have caused little damage, they can often have a significant political impact. This obviously also brings new topics to the safety protection of large-scale infrastructure and important activities in the country

experts believe that there are three main reasons why these small UAVs frequently make significant international impact: first, these small UAVs are not easy to detect at ordinary times. Because of their small size, low altitude and slow speed, they are difficult to detect by traditional radar. Complete the tensile, compression and bending tests of the samples. In particular, most countries cannot achieve full coverage of such small ultra-low altitude targets. Once they launch a sneak attack from within or cross the boundary line, they will be easy to succeed. Second, the countries concerned lack effective interception means and are somewhat relaxed in terms of protection. Third, such attacks often occur on important occasions and occasions. Even if the losses are small, the impact is not small

there are different ways to detect, intercept and drive away

experts said that the success of UAV attacks in recent years should be said to be "surprise", and the success of this attack was also due to surprise. In fact, countries have developed perfect UAV detection, tracking, interception and countermeasures systems. If a relatively complete defense system is deployed in advance, at least it will not cause so much loss

the primary problem in dealing with this kind of UAV is to solve the problem of difficult discovery. In addition to continuously improving radar performance and adding temporary deployment points, it can also assist detection through a variety of means. The first is the infrared search and tracking system. At present, this kind of system has been very mature and is widely used for air and ground detection. Because of its small size, it does not radiate electromagnetic waves, so it is very suitable to be arranged near important urban areas to detect small targets

in addition, UAVs can be detected through radio environmental monitoring. Once the UAV control signal is found, it can give an early warning, and can also locate its control source and the UAV that sends the radio signal. This combination of active detection and passive monitoring can detect small civil UAVs around key targets with high probability

after passing the detection pass, you have to pass the interception pass. The most direct way is "hard kill". Some anti-aircraft guns and missiles can intercept at greater distances. The Russian military base in Syria has been attacked by small unmanned aerial vehicles for many times, and most of the unmanned aerial vehicles have been shot down by the Russian "armor" missile artillery integrated air defense system. Of course, in downtown areas, the collateral damage caused by anti-aircraft guns and missiles may be greater than that caused by small unmanned aerial vehicles, which gives birth to a new hard killing means - lasers. At present, anti UAV lasers are almost blooming

even if there is no effective physical kill, or even if no UAV is found, small UAVs can be driven away or forced to land by means of "soft kill". At present, civil consumer UAVs mainly implement positioning and navigation through GPS and other satellite navigation and positioning systems. If their navigation channels are blocked, these UAVs may become "headless flies". In the vicinity of important targets, the UAV is forced to be unable to receive navigation signals through GPS interference, which may drive or crash land the civil UAV. GPS deception technology is even used around the Kremlin in Russia to replace the GPS signal near the Kremlin with the signal from another area, making the civil UAV "dizzy" and unable to find the real target even if it enters the relevant area

in addition to suppressing the GPS signal, it can also interfere with the control link of the UAV, make the UAV out of control, or obtain its control right, and then make a forced landing and drive the UAV away
