SpectraGuard™
Invisible Defense: Detect Drones Passively and Precisely
SpectraGuard™ is an advanced counter-UAS system designed for passive detection, tracking, and identification of drones through a modular, scalable architecture. By remaining passive, distributed, and intelligent, SpectraGuard™ (Spectral Passive Edge Reconnaissance and Threat Assessment Guard) creates a detection layer that is difficult to locate, difficult to overwhelm, and economically viable to deploy at scale.​
​
The Rapidly Evolving UAS Challenge
The aerial threat environment has fundamentally changed. Low-cost, autonomous drones are now deployed in saturation swarms.
Many operate without RF emissions, without GPS, and without human control.
​
As the threat evolves, traditional C-UAS architectures become a liability.
Systems, built around active sensors and centralized architectures, are increasingly expensive, detectable, and fragile. Cost and logistics prevent large-area coverage. SpectraGuard™ was designed for this reality.
"As the UAS mice proliferate, our design philosophy is not to build bigger traps, instead we built an AI-powered CAT.”
SpectraGuard is not a single sensor or platform. It is a System-of-Systems architecture that uses intelligence, distribution, and passivity to reverse the asymmetry created by cheap drones.
​
Instead of concentrating capability, SpectraGuard spreads it. And we always stay a step ahead with a continuously learning AI powered system.

System Overview
SpectraGuard is an advanced counter-UAS system designed for passive detection, tracking, and identification of drones through a modular, scalable architecture. It comprises three core components: BASE node for foundational sensing, TAG nodes for distributed expansion, and the Fusion engine for intelligent data integration. This setup enables robust performance in challenging environments, leveraging multi-sensor fusion without active emissions or kinetic interventions.

SpectraGuard Base
SpectraGuard Tag Sensors
SpectraGuard Fusion Layer
BASE nodes provide broad-spectrum awareness and serve as high-fidelity anchors within the system.
Wideband Passive Sensing Node
-
Continuous passive RF monitoring
-
Coverage from 433 MHz to 5.8 GHz
-
No RF emissions
-
Designed for fixed or semi-fixed installations​
TAGs form a cooperative sensing mesh that functions as a distributed radar, increasing detection range, resilience, and survivability.
​
Distributed Low-Cost Sensing Node
-
Ultra-low-cost passive sensing
-
Designed for dense, scalable deployment
-
Focused ISM band detection (2.4 GHz)
-
Enables spatial correlation across large areas​
SpectraGuard Fusion uses AI to correlate signals across space, time, and frequency:
​​
-
Multi-node signal fusion
-
Pattern recognition and classification
-
Early warning and tracking
-
Robust performance in cluttered RF environments
-
Detection improves as more nodes are added, rather than degrading under load.
