«Pyramid» Acoustic UAV Detection System

Networked Acoustic Early UAV Detection System.

«Pyramid» is an outdoor acoustic module designed for the early detection of unmanned aerial vehicles based on acoustic signatures. The device analyzes the local acoustic environment, determines the direction of the signal source, and transmits compact event data to the monitoring system without sending raw audio.
The system can operate not only in open areas but also on complex terrain: individual modules can be combined into a single distributed network and use repeaters to transmit data between remote points. This makes it possible to deploy an acoustic perimeter at sites with elevation differences, natural obstacles, and limited direct radio visibility.
The protected enclosure is designed for outdoor operation and installation on masts, walls, and field structures. The modular architecture allows the system to be used in a basic acoustic configuration and expanded with a concentrator, radio communication, and an upper vision module for visual confirmation.

UAVs have become inexpensive, widespread, and quiet.
Standard security systems cannot detect them.

Specialized sensors are required that can:

detect small targets;
operate in complex environments;
provide data for automated response.

We can integrate third-party detection systems, including:

Radar

Primary detection

Acoustics

Direction refinement

Video

Visual confirmation

All data is aggregated within a unified platform

Electronic warfare (EW) initiates target suppression

Before it becomes too late

Modular drone detection systems include:

Radar
Acoustics
Video detection

These solutions can operate independently or in combination, complementing each other.

Coordinated Operation

Systems can:

Operate autonomously;
Operate in pairs;
Operate in a full multisensor configuration.

All elements are connected by their own secure radio network, ensuring stable and reliable operation of the system.

Proprietary Radio Communication

All modules are unified through their own secure radio network.
