U.S. Startup Hunts FPV Drones Using Sound Alone
AI Analysis
Talon Avionics, a U.S. startup, has developed the SECTR platform, a counter-drone system using AI-powered acoustic sensing to detect and intercept FPV drones. The system employs a modular interceptor station with drones equipped with microphones to isolate and target drone motor signatures, providing an advantage over conventional radar systems.
Key Takeaways
- SECTR platform uses AI-powered acoustic sensing for drone detection.
- System includes a modular interceptor station with up to 100 drones.
- Acoustic detection range is up to 330 feet, with radar extending to 3,280 feet by 2027.
- Interceptors are lightweight, equipped with 16 microphones for sound isolation.
- Designed for convoy escort, base defense, and infrastructure protection.
Why It Matters
The SECTR platform represents a significant advancement in counter-UAS technology by leveraging acoustic sensing, which can detect drones that are often invisible to radar. This capability is crucial for defending against small, fast-moving FPV drones, enhancing protection for military convoys and critical infrastructure against emerging drone threats.

A Boise, Idaho company called Talon Avionics has built a counter-drone system that doesn’t start with radar. It starts with microphones. The SECTR platform uses AI-powered acoustic sensing to detect, track, and physically destroy hostile FPV drones before traditional sensors even register the threat, as Militarnyi reports.
How SECTR Works
The system is built around the SECTR-IK-02 interceptor station, a modular launch platform arranged in a 10×10 grid that holds up to 100 interceptor drones. A single operator runs the whole thing from one control station.

The platform mounts on a vehicle or deploys as a fixed position, which makes it viable for convoy escort, forward operating base defense, and critical infrastructure protection.
Detection starts with a proprietary acoustic array that picks up drone motor signatures at distances up to about 330 feet. That doesn’t sound like much until you consider the context. FPV drones are small, fast, and often invisible to conventional radar at close range.

The acoustic layer catches them first, giving the system a head start. Integrated radar then provides wider surveillance starting around 660 feet, with plans to extend that range to roughly 3,280 feet by Q2 2027.
Each interceptor weighs just about 1.5 lbs including its launch tube, and measures roughly 4 x 4 x 10 inches. When the system identifies a threat, the entire sequence from detection to launch completes in under one second. That’s not a typo. Talon Avionics claims the full detect-classify-launch cycle happens faster than a human could react.
The Acoustic Edge
The real innovation sits inside each interceptor drone. Every unit carries an array of 16 microphones that scan the airspace in all directions, forming a narrow acoustic beam to isolate the sound signature of a hostile drone. An onboard AI model then separates the target’s motor noise from the interceptor’s own engines and ambient wind. That distinction is critical. Without it, the interceptor would chase its own sound.

This approach gives SECTR a specific advantage against what Talon Avionics calls “sleeper drones,” threats pre-positioned near roads or terrain that power up only when vehicles or troops get close. Because the acoustic sensors pick up motor signatures the instant they start, the system generates a warning before radar even registers the threat. Seconds matter in that scenario, and SECTR is designed to convert those seconds into a kill.
