In recent years, global airports have frequently experienced security incidents involving deliberate sabotage of physical perimeters, illegal intrusions into aprons, and even unauthorized access to aircraft cabins, posing serious threats to aviation safety. Such events not only expose vulnerabilities in existing security systems but also highlight the urgent need for smarter and more reliable airport security technologies.
Currently, mainstream airport perimeter security technologies, such as electronic fences and video surveillance, suffer from high false alarm rates and susceptibility to adverse weather conditions. Under extreme conditions like strong winds, rain, snow, or hail, system performance significantly declines. Video surveillance still relies on manual identification and lacks proactive warning capabilities. Therefore, upgrading security systems toward networking, digitization, intelligence, and multi-technology integration has become an industry consensus.
Major Issues with Current Airport Security Technologies
Commonly adopted security measures at airports include perimeter protection solutions based on physical sensors, such as electronic fences and vibration-sensitive cables. These technologies face the following significant challenges in practical applications:
1. Lack of Automatic Tracking and Continuous Detection Capabilities
Traditional linear detection systems (e.g., vibration optical fibers, vibration cables) can only monitor localized areas around the perimeter fence and are unable to achieve automatic identification and continuous tracking of intruders. Once an intruder crosses the fence, the system loses track of the target, creating security blind spots.
2. High False Alarm Rate and Limited Monitoring Methods
Existing systems are prone to weather-related interference, leading to frequent false alarms, which severely impact the efficiency of security personnel in responding to real threats.
3. High Construction and Operational Costs
Traditional sensors have limited coverage, requiring dense deployment of equipment and cabling. This complicates construction and may disrupt airport operations. Additionally, post-deployment maintenance is labor-intensive, and system failure rates are relatively high.
Intelligent Airport Security Solutions
In response to the above challenges, next-generation intelligent security systems featuring radar and video integration demonstrate significant advantages:
1. Wide-Area Multi-Target Detection Capability
Radar perimeter systems enable area-wide coverage, monitoring not only the perimeter line but also extending to continuous internal and external zones. They support simultaneous detection and tracking of multiple targets. For large airports, multi-radar networking can achieve cross-coverage, significantly enhancing security levels.
2. Low False Alarm Rate and Multi-Method Coordination
The radar-and-camera integrated system can continuously discriminate and track suspicious targets after detection, greatly reducing false alarms. Radar technology does not rely on optical imagery, is unaffected by weather conditions, and does not require vibration sensing, effectively avoiding interference from wind and rain while ensuring detection accuracy and reliability.
3. Low-Cost Construction and Convenient Operation
This system leverages the all-weather, wide-coverage, and continuous tracking capabilities of radar to automatically guide cameras for capturing images and recording. Through multi-radar networking, it achieves seamless monitoring of airport perimeters and critical areas. With a monitoring radius of up to eight kilometers, the system offers high reliability and strong environmental adaptability, significantly reducing construction and operational costs.
