Shulou(Shulou.com)11/24 Report--

On September 9, Venezuelan President Maduro arrived in China by special plane to begin his state visit and watch a grand drone light show in Shenzhen. Maduro expressed great shock and sighed: when you come to China, you come to the future.

Dramatically, Maduro was attacked by several drones carrying C4 explosives in 2018, but fortunately he was not hurt in this incident.

It is worth noting that drone attacks are not uncommon.

On October 5, a military academy in Homs province in central Syria was attacked by a drone during a graduation ceremony, killing 89 people and injuring 277. On the 7th, the Syrian Defense Ministry issued a statement that the Syrian army shot down seven drones aimed at residential areas on the same day to avoid a greater disaster.

Disorderly unmanned flight has caused great harm to the life and property safety of the country and the people. Timely and effective detection can avoid the occurrence of disasters.

I. possible threats to unmanned aerial vehicles

Unmanned aerial vehicle (UAV), as a rapidly developing scientific and technological innovation product in recent years, has played an important role in inspecting traffic, surveying and mapping topography, irrigation and water conservancy and other fields. the following problems have become increasingly prominent: unidentified aircraft intruding into critical and sensitive areas, interfering with the normal flight of civil aviation aircraft, aerial photography leaking national defense secrets and other incidents are increasing. And it is worth noting that once the threat occurs, it will cause huge losses and injuries.

The possible threats to unmanned aerial vehicles mainly include the following aspects:

1. Threaten military security. Some simple aircraft, such as power parachutes and hot air balloons, have weak autonomous navigation and communication capabilities, and are prone to deviate from the intended route and airspace. Once they break into the air of an important target, it is likely to endanger the safety of the target, or even cause serious impact.

two。 Potential threat of violent terrorism. UAV itself has a certain load, a little modification can become an offensive weapon, if the supervision is not effective, it will pose a direct or potential threat to national air defense security, important target security, security security and so on.

3. Disturb the aviation order. UAV is mostly made of non-metallic materials, small size, low height and slow speed, so it is difficult for civil aircraft to find and avoid, and there is great interference to civil aviation routes.

4. Violating the safety of the ground. The flight of UAV is easily affected by complex electromagnetic environment, and it is very likely to lose control and fall during flight, resulting in safety accidents, and even seriously affect public safety.

Second, how to detect unmanned aerial vehicles quickly and accurately from a long distance?

Due to electromagnetic interference, easy confusion between UAV and birds or aircraft, and bad weather with low visibility, it is difficult for radar system to identify small UAV and ultra-long-distance flying UAV. There are some difficulties in UAV detection.

In view of the existing difficulties in UAV detection, Lithor infrared has made a breakthrough through continuous technical research. The search, detection and recognition of small UAV such as Dajiang elf 4 can reach more than 8KM, and ultra-long-distance fast and accurate detection has been realized.

The photoelectric search and detection system of Lide infrared UAV is mainly used to search, capture, track and measure the flying target, and output the high-precision position information of the target in real time. The system can search the target in 360 °omni-direction.After the target is captured, it is transferred to the automatic tracking mode, and the target is automatically tracked, identified and position measured by infrared, visible light and laser.

The excellent performance of Lide infrared UAV optoelectronic search and detection system is mainly proud of the multi-party characteristics of the products. it includes multi-band fusion intelligent detection, high measurement accuracy, accurate target detection and recognition under complex background, and strong anti-jamming ability and survivability.

Multi-band fusion intelligent detection: the system uses visible light, infrared, laser and microwave multi-bands, which greatly improves the target detection ability and solves the difficult problem of "low, small and slow" target detection under night vision and low visibility. All-weather, all-weather detection

High measurement accuracy: the angle measurement accuracy of the system is much higher than that of radar, which can not only provide early warning information, but also accurately guide the equipment to deal with the target.

Accurate target detection and recognition under complex background: the system solves the problem of target detection in complex background such as low altitude, ground and sea surface. Through artificial intelligence technology, the target can be identified quickly, and the disposal effect evaluation can also be realized.

Strong anti-jamming and survivability: the system can independently use photodetectors to detect targets using their own optical characteristics and infrared radiation characteristics, so it is not easy to be interfered by electronic. Because it is passive detection, it is not easy to find itself.

In addition to the outstanding advantages in UAV monitoring, Lithor infrared UAV photoelectric detection system is also widely used in border and coastal defense, key protection, UAV monitoring, oil depot security and other fields, and has been widely recognized.

Safety is more important than Mount Tai, and prevention is greater than before. Air threats can not be ignored, timely detection can avoid the occurrence of disasters.

As a national high-tech enterprise in the field of UAV detection and defense, Lide Infrared will continue technological innovation, focus on the research of UAV defense technology, detect UAV quickly and accurately with sophisticated products, and make a contribution to the protection of the lives and property of the country and the people.
