14:26 Foreign Object Debris (FOD) remains one of the most serious safety risks in civil aviation. A small metal fragment as tiny as 1 cm can cause severe aircraft damage during takeoff or landing, leading to costly delays, runway closures, and safety hazards.
Traditional manual inspection methods are slow, labor-intensive, and cannot operate efficiently in poor weather or at night.
The W-Band Synthetic Aperture Radar (SAR) Airport FOD Detection System provides a breakthrough solution for modern airports, enabling high-speed, high-accuracy, and all-weather runway inspection without interrupting airport operations.
Vehicle-Mounted Mobile FOD Detection System Concept Illustration
Le W-Band radar (75–110 GHz) is an advanced millimeter-wave sensing technology designed for ultra-high-resolution detection.
Our system operates in the 92–94 GHz atmospheric low-loss window, making it ideal for airport surface monitoring.
Key Advantages of W-Band Airport Radar:
This makes it one of the most effective technologies for runway inspection radar systems and airport surface safety monitoring.
Synthetic Aperture Radar (SAR) uses platform motion to generate high-resolution imaging, allowing continuous runway scanning while moving.
Our Mobile Airport FOD Detection System is mounted on a standard inspection vehicle and does not require runway closure.
Working Process:
1. High-Speed Runway Scanning
The system operates at 40–80 km/h without interrupting airport traffic.
2. Real-Time SAR Imaging
Side-looking SAR generates high-resolution runway surface maps in real time.
3. AI-Based FOD Detection
Artificial intelligence automatically detects foreign objects and calculates precise coordinates (≤1 m accuracy).
4. Intelligent Maintenance Guidance
The system provides optimized removal paths for maintenance teams.
👉 A full 3 km runway can be inspected in approximately 5 minutes.
