Mobile, High-Speed & All-Weather Airport Runway Safety Technology
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.

What Is W-Band Radar in Airport FOD Detection?
Die 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:
- Centimeter-Level Detection Accuracy (≈1 cm FOD detection)
- Strong Metal Target Sensitivity (high RCS response)
- All-Weather Operation (fog, rain, snow, dust, night conditions)
This makes it one of the most effective technologies for runway inspection radar systems and airport surface safety monitoring.
Mobile SAR Technology for Runway Inspection
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.
