During the hosting of the Boao Forum for Asia in Hainan, UAV countermeasure support has become a crucial link in ensuring the smooth progress of the forum. To effectively address potential safety risks posed by UAVs, the relevant support team has meticulously prepared, scientifically deployed, and utilized advanced technologies and strict measures to fully safeguard the airspace safety of the forum.

As early as the forum preparation stage, the UAV countermeasure support team conducted detailed surveys of the terrain, distribution of event venues, and surrounding airspace conditions in the Boao area. Based on this, they established a comprehensive and multi - layered UAV monitoring system. With radio detection as the core, 24 - hour real - time monitoring is carried out on common UAV communication frequency bands, such as 420MHz - 450MHz and 2400MHz - 2450MHz, to promptly capture the signal traces of UAVs. Meanwhile, high - performance radar detection equipment is deployed, which actively emits modulated radio signals and can accurately obtain key information such as the distance, azimuth, and speed of UAVs. It can effectively detect targets even in complex weather and at night. In addition, optical detection equipment also plays an important role. High - resolution cameras cooperate with radar and radio detection systems to accurately identify suspected UAV targets and avoid misjudgment.

To ensure the ability to quickly and effectively respond to UAV emergencies during actual support, the support team has carried out multiple practical drills. Various scenarios of illegal UAV intrusions are simulated, and each link from target discovery, information confirmation, to the activation of interference and countermeasure measures is repeatedly deduced and optimized. Team members have mastered the operation skills of countermeasure equipment such as electromagnetic interference guns and laser interception systems proficiently, and can flexibly select appropriate countermeasure methods according to the type, distance, and threat level of UAVs. For example, for civilian UAVs that are relatively close and pose less threat, electromagnetic interference guns are preferentially used to block their communication links, forcing them to automatically return or make an emergency landing; for UAVs that may carry dangerous items and pose a higher threat, the laser interception system is decisively activated to quickly destroy the targets, ensuring the absolute safety of the core area of the forum.

UAV countermeasure support involves multiple departments and professional fields. To achieve efficient collaboration, the support team has established a complete linkage mechanism. It closely cooperates with the local police and security departments to realize real - time information sharing. Once a suspicious UAV is detected, the surrounding police are immediately notified to conduct ground investigations to prevent the operators from escaping. At the same time, it cooperates with the communication department to ensure the unobstructed communication of countermeasure equipment and guarantee the timeliness and accuracy of command and dispatch. In addition, the various groups within the team have clear divisions of labor and close cooperation. The monitoring group promptly provides accurate UAV information, the countermeasure group takes quick actions, and the logistics support group provides solid material support for equipment operation and personnel work, forming a closely cooperating organic whole.

During the hosting of the forum, members of the UAV countermeasure support team stuck to their posts and carried out 24 - hour uninterrupted duty. They constantly monitored the operation status of the monitoring system and did not let go of any suspicious signal. Whether in the scorching daytime or the silent night, they remained highly vigilant and were always ready to respond to emergencies. It is precisely this rigorous and responsible work attitude and persistent efforts that have created a safe and stable air environment for the smooth holding of the Boao Forum for Asia, effectively preventing the occurrence of UAV interference incidents, and demonstrating China’s professional capabilities and high - level support strength in the security of large - scale international events to the world.
