FlySpark 360° Acoustic Drone Detection System | 3-Array 64-Channel Passive UAV Sound Detection Platform with AI Voiceprint Recognition

Key facts

At a glance

The FlySpark 360° Acoustic Drone Detection System is a passive, non-emitting sensor that detects drones by their sound using three 64-channel microphone array discs on a triangular fixture, each covering 120°. It is intended for protected sites that need silent early warning, alone or alongside RF, radar and EO/IR sensors. Each array samples at 48 kHz / 24-bit and is listed for 8–12 simultaneous targets (up to 16 under suitable conditions).

Use cases

• Passive drone early warning at sites where RF emission is not wanted
• Airport, prison and critical-infrastructure perimeter monitoring (subject to security approvals)
• Acoustic layer in a multi-sensor C-UAS setup with RF detection, radar and EO/IR
• OEM/ODM acoustic detection development under agreement

Intelligence Brief

Mission overview

FlySpark 360° Acoustic Drone Detection System is a passive acoustic UAV detection platform designed for drone sound sensing, direction awareness, multi-target acoustic detection, security monitoring, counter-UAV early warning, and protected-site surveillance. The system uses three 120° acoustic array discs to create full 360° coverage around the protected area.

Each acoustic array disc is built around a 64-channel microphone array structure with a 460mm array aperture and multi-arm spiral microphone layout. The platform supports microphone frequency response from 20Hz to 20kHz, sound pressure level range from 25dBSPL to 128dBSPL, continuous synchronous sampling, 48kHz sampling rate, and 24-bit sampling width. The system is designed to detect drone acoustic signatures passively without emitting RF signals, making it suitable for sites where silent detection, passive observation, and non-emitting security sensing are required.

The system supports single-array multi-target detection of 8 to 12 drones simultaneously, with maximum support for up to 16 drones per array under suitable conditions. For 360° coverage, three acoustic array panels are installed on a triangular fixture, with each disc covering approximately 120°. The 3-array fixture is designed to place the panels around the center structure at 120° intervals, creating full circular acoustic coverage.

The platform can work with USB and DC 12V power input modes, and supports communication through USB for video and beam data, as well as UDP for raw data. The product also supports a camera interface with 1920×1080 / 1280×720p at 25Hz and 63° viewing angle, depending on the selected configuration. Visual gimbal is not included in the base 3-array sample package unless separately quoted.
