U.S. Startup Develops Technology to Locate FPV Drones Using Sound Detection
Talon Avionics Develops Innovative Counter-Drone System
A Boise, Idaho-based company, Talon Avionics, has introduced a counter-drone system that utilizes microphones instead of traditional radar for detection. The SECTR platform employs AI-powered acoustic sensing to identify, track, and neutralize hostile FPV drones before they are detected by conventional sensors, as reported by Militarnyi.
Overview of the SECTR System
The SECTR system is centered around the SECTR-IK-02 interceptor station, which features a modular launch platform arranged in a 10×10 grid, capable of holding up to 100 interceptor drones. A single operator can manage the entire system from one control station.
The platform can be mounted on a vehicle or deployed in a fixed position, making it suitable for various applications, including convoy escort, forward operating base defense, and protection of critical infrastructure.
Detection Capabilities
Detection begins with a proprietary acoustic array that can capture drone motor signatures from distances of up to approximately 330 feet. This range is significant considering that FPV drones are often small, fast, and difficult to detect with conventional radar at close range.
Once a potential threat is identified, integrated radar provides broader surveillance starting at around 660 feet, with plans to extend this range to about 3,280 feet by the second quarter of 2027.
Interceptor Drone Features
Each interceptor drone weighs about 1.5 pounds, including its launch tube, and measures approximately 4 x 4 x 10 inches. The entire process from detection to launch can be completed in under one second, which is faster than human reaction times.
Acoustic Technology
The innovation of the SECTR system lies within each interceptor drone, which is equipped with an array of 16 microphones. These microphones create a narrow acoustic beam to isolate the sound signature of a hostile drone. An onboard AI model distinguishes the target’s motor noise from the interceptor’s own engines and ambient sounds, which is crucial for effective targeting.
This capability provides a significant advantage against “sleeper drones,” which may remain inactive until they detect nearby vehicles or troops. The acoustic sensors can detect motor signatures immediately upon activation, allowing for a timely response before radar systems can register the threat.
Specifications and Future Plans
The SECTR-IK-02 station can support up to 100 launch tubes in its full configuration and can operate continuously for up to 24 hours on a single battery charge. It is designed to function in extreme temperatures, ranging from -40°F to 185°F.
Talon Avionics has established partnerships in the U.S., Poland, and Saudi Arabia, and recently opened a seed funding round to finalize production tooling and scale the platform. The system is manufactured entirely in the United States, with plans for localized production for allied partners.
However, the company has not disclosed unit pricing, production timelines, or confirmed customer contracts, as the system remains in active development.
Challenges and Considerations
While the SECTR system presents an innovative approach to counter-drone technology, several questions remain unanswered. The acoustic detection range of 330 feet may be limited in real-world scenarios, where ambient noise from vehicles and gunfire could further reduce effectiveness. Additionally, the current radar integration only extends to 660 feet, with the longer range still under development.
The claimed 95% kill probability also requires validation in battlefield conditions, as real-world performance can differ significantly from laboratory settings. Comparatively, existing interceptor programs have demonstrated lower kill rates in actual combat situations.
Furthermore, the absence of pricing information raises concerns about the system’s cost-effectiveness compared to traditional counter-drone solutions.
Conclusion
The SECTR system represents a promising advancement in counter-drone technology, leveraging passive acoustic detection to enhance operational effectiveness. However, the need for thorough battlefield testing, transparent pricing, and confirmed orders remains critical before the system can be fully endorsed. Talon Avionics, as a seed-stage startup, faces the challenge of transitioning from a compelling concept to a reliable defense solution.
