In recent years, a series of unsafe accidents have occurred in airports at home and abroad, such as deliberate knocking and impact, climbing over, shearing and destroying the physical enclosure of the flight area, breaking into the apron or diving into the cabin, which has caused great harm to airport security. Therefore, for the airport, the use of more secure, reliable, flexible management of the airport security system technology is very necessary.
In recent years, a series of unsafe accidents have occurred in airports at home and abroad, such as deliberate knocking and impact, climbing over, shearing and destroying the physical enclosure of the flight area, breaking into the apron or diving into the cabin, which has caused great harm to airport security. Therefore, for the airport, the use of more secure, reliable, flexible management of the airport security system technology is very necessary.
Airport Security Difficulties
The mainstream perimeter security technology that everyone sees now is susceptible to weather, especially in strong winds and hail weather, and the false alarm rate is relatively high; video surveillance is also greatly affected by the weather, without early warning and alarm functions, and requires manual remote interpretation; In this case, the improvement of airport security is particularly urgent. At present, the airport security system is developing in the direction of network, digital, intelligent and multi-technical means.
Current Technical Means and Problems
At present, the airport security mainly uses electronic fence, vibration cable and other physical perimeter-based sensor technology, this scheme has the following disadvantages.
NO.1No automatic tracking detection capability
Traditional linear detection systems, such as vibrating optical fibers and vibrating cables, can only cover the perimeter fence area and do not have the ability of automatic target detection and tracking. Once the intruder leaves the fence area, the airport monitoring system will immediately lose the target.

NO.2High false alarm rate, single monitoring means
The traditional detection scheme is easily affected by the weather, which may produce a large number of false alarms, and the false alarm rate is relatively high, which interferes with the management of the scene.

NO.3High construction cost and difficult operation
Traditional linear sensors, the coverage length of each sensor is limited, which causes the establishment of the security system to lay a large number of sensors, which means a large number of pipelines and on-site construction, which poses challenges to the normal and uninterrupted operation of the airport. Correspondingly, in the later operation and maintenance process, a large number of equipment will also cause an increase in maintenance workload and an increase in system failures.
Analysis of scheme
The above picture shows the interface of the system.
With the help of radar technology, airport perimeter security solutions have the following characteristics:
NO.1large area multi-target detection capability
The radar perimeter uses a wide-area surface coverage detection, which covers not only the perimeter, but also a continuous area inside and outside the perimeter, so the radar coverage should be able to detect multiple intrusion targets at the same time. If the perimeter area of the airport is large, multi-radar systems can also be used to cross-cover and increase the security of the system.
NO.2Low false alarm rate and diverse monitoring methods
Compared with the traditional perimeter security scheme, the thunderball linkage scheme can continue to distinguish and track suspicious targets with low false alarm rate. Moreover, radar technology does not depend on video images, so it will not be unable to detect due to bad weather conditions. It also does not use vibration sensing technology, so it will not be affected by strong winds, heavy rain, etc., thus greatly increasing the accuracy of detection.
NO.3Low construction cost and simple operation
Through the linkage of radar and video, this scheme gives full play to the characteristics of radar all-weather, wide protection range and continuous tracking of intrusion targets. The radar is responsible for the discovery and tracking of intruding targets, automatically guiding the camera to capture continuous shots. Through multiple radar networks, there is no dead angle to cover the perimeter of the entire airport and some key areas. The monitoring range of the radar can reach about eight kilometers, which has the outstanding advantages of high reliability and all-weather work.
