As vital civil aviation infrastructure, airports face severe safety risks from unauthorized drones, which commonly trigger flight delays, diversions and forced landings, and may even cause aircraft collisions and engine damage. To tackle such threats, reliable C-UAS defense is indispensable. The integrated linkage of passive sensors, radar and electro-optical spheres delivers accurate drone identification and timely interception, effectively safeguarding airport airspace and aviation operational safety.
Traditional radar and RF systems suffer from limited detection coverage. Blocked by surrounding buildings and wooded areas, they form extensive low-altitude blind zones, failing to stably capture small, slow-flying low-altitude drones and resulting in frequent target missed detection and airspace monitoring gaps.
Conventional active radar and RF devices continuously emit electromagnetic radiation, which may interfere with precise aircraft navigation and communication signals. Such equipment fails to meet strict airport electromagnetic compatibility standards and poses persistent potential safety hazards to aviation operations.
Existing airport radar and electro-optical devices operate independently with isolated data and no collaborative scheduling mechanism. Lacking functional complementation and redundant backup, single-device detection failure easily causes defense gaps and breaks the integrity of the overall airspace security system.
Independent radar or electro-optical detection has limited recognition capability. It cannot effectively distinguish drones from interference sources such as birds and environmental clutter, leading to frequent false and missed alarms. These invalid disturbances interfere with air traffic judgment and scheduling and fail to meet high-precision airport security management requirements.
Tailored specifically for airport C-UAS scenarios, the HEIMDALL multi-modal sensor cluster supports deep linkage with existing airport radar and electro-optical systems. It establishes a three-in-one collaborative detection architecture featuring radar wide-area early warning, passive sensor high-precision positioning, and electro-optical sphere visual verification. The solution comprehensively compensates for the defects of single-device detection and builds a covert, full-coverage, 24/7 low-altitude airspace early warning and defense capability for airports.
Complementing radar and electro-optical detection limitations, acoustic sensing effectively fills low-altitude blind zones occluded by buildings and vegetation. It stably captures tiny, slow-flying drones that traditional devices easily miss, eliminating monitoring gaps and achieving complete, gap-free coverage of airport low-altitude airspace.
Adopting fully passive detection mode with no RF signal radiation, the system will not interfere with aircraft navigation and communication equipment. It fully complies with strict airport electromagnetic compatibility specifications and fundamentally eliminates potential aviation safety risks caused by electromagnetic interference.
The system breaks data isolation between radar, electro-optical spheres and passive sensors through a unified collaborative scheduling mechanism. Complementary functions and mutual redundant backup effectively solve the problem of isolated device operation and prevent airspace defense faults caused by single-device failure.
Combining AI algorithms with multi-device cross-verification, the system breaks through the accuracy limitations of traditional single-mode detection. It accurately distinguishes real drone threats from birds and environmental interference, drastically reducing false and missed alarms and ensuring efficient and precise air traffic judgment and scheduling.
