In modern aviation, a single unauthorized drone sighting can paralyze an entire airport in minutes. Unauthorized UAV intrusions lead to grounded flights, diverted passengers, and millions of dollars in operational losses, not to mention the catastrophic safety risks to aircraft during takeoff and landing. However, airports face a unique technical dilemma: many traditional active radar systems can interfere with sensitive flight navigation and communication frequencies. To solve this, Terjin TDOA FTD1 is a specialized silent detector designed to identify drones without emitting a single radio wave.
The Power of Passive RF Sensing
The FTD1 is not a jammer or a traditional radar; it is a high-precision Passive RF Sensing device. Think of it as a highly trained security guard who listens intently rather than shouting signals into the environment.
- Zero Interference: Because the system only “listens” to radio signals across a wide 100 MHz to 6 GHz range, it provides 0% interference with critical airport ILS (Instrument Landing Systems) or VHF communications.
- Stealth Monitoring: Since the FTD1 does not transmit any signals itself, it remains invisible to attackers. An unauthorized pilot cannot detect the presence of the monitoring station, preventing them from evading security.
- Urban Clarity: Airport terminals are crowded with WiFi, Bluetooth, and cellular noise. The FTD1 features a strong anti-interference capability, allowing it to surgically separate a tiny drone signal from thousands of smartphones and routers.
Precision Tracking and Swarm Readiness
Aviation security requires more than just knowing a drone is “nearby”; it requires exact coordinates and rapid response times. The TDOA FTD1 is engineered to meet these stringent requirements:
- 6km Early Warning: With a detection radius of 2–6 km, the system identifies drones long before they enter restricted flight paths, giving security teams ample time to respond.
- Instant Updates: The system boasts a high refresh rate of less than one second, providing real-time movement tracking on a map.
- TDOA Positioning: By networking multiple FTD1 units together, the system uses Time Difference of Arrival (TDOA) technology to calculate the exact 3D location of the drone in the sky.
- Swarm Defense: Modern threats are evolving. The FTD1 can simultaneously track 10+ drones, ensuring the airport is protected even against coordinated multi-drone incidents.
- The Whitelist Advantage: The system includes a smart “Whitelist” function. This allows airport authorities to use their own authorized drones for runway inspections or perimeter patrols while only triggering alarms for unknown “intruder” UAVs.
Redefining Aviation Hub Security
Safety in the sky begins with total visibility on the ground. The TDOA FTD1 offers an integrated, all-in-one design that is easy to install on existing airport towers and simple to maintain. With a database that stays updated as new drone models enter the market, your airspace remains future-proof against the next generation of unmanned threats.
