Passive RF Sensor
PASSIVE RF DETECTION & UAV SIGNAL INTELLIGENCE
The HADES Passive RF Sensor A passive electronic support sensor has been developed for RF detection, UAV signal intelligence and integrated Counter-UAS operations within complex operational environments.
The system continuously monitors the RF spectrum without emitting any signals itself, thus enabling completely passive and low-signature deployment within tactical, critical infrastructure, border surveillance, and airspace security environments.
Wideband Awareness in One Device
Detects all major RF and drone emitters across 0-6 GHz with instant precision.
Technical specifications
The sensor detects, classifies, and analyses command-and-control links, telemetry links, and video data links originating from both commercial and military UAV platforms.
The model shown supports wideband RF awareness within the 0–6 GHz frequency range (customisable up to 100 GHz), combining high sensitivity with real-time RF detection capabilities within a single compact operational platform.
By utilising emitter and protocol libraries, detected RF signatures can be correlated with known communication profiles, waveform behaviour and emitter characteristics to support rapid identification, threat analysis and operational decision-making.
Tactical added value
Simultaneous radar and RF detections can indicate actively controlled platforms, while radar tracks without RF activity may point to autonomous, pre-programmed, or emission-controlled threats. This provides operators with additional tactical context for threat analysis, prioritisation, and engagement assessment.
Operational architecture
The HADES Passive RF Sensor can operate fully autonomously with embedded local processing and detection capabilities, enabling standalone deployment as an independent operational sensor node.
As part of the HADES C4ISR Platform, the system contributes to distributed sensor fusion, RF-based situational awareness and an integrated Common Operational Picture (COP).
When integrated with radar, EO/IR, and external command and control systems, the sensor supports real-time correlation between RF detections, radar tracks, and optical observations.
Multiple sensors can be linked within a single operational architecture to significantly enhance RF coverage, situational awareness and geolocation accuracy over large areas.
Thanks to the software-defined architecture, expandable emitter libraries, and flexible backend environment, the sensor can be adapted to new UAV platforms, emerging communication protocols, and mission-specific operational requirements.
Stake configurations
The scalable deployment architecture supports:
- Fixed installations
- Mobile platforms
- Telecommunications mast infrastructure
- Distributed multi-node RF networks
- Border and coastal surveillance environments
Integration & interfaces
Via open interfaces and API-based architectures, the system can seamlessly integrate within existing third-party operational environments, including Counter-UAS architectures, sensor fusion platforms, command environments, and national or NATO operational networks.
The system supports real-time visualisation of detected emitters, RF events and correlated sensor tracks within a single integrated operational environment.
The sensor and specifications shown serve as examples from our standard portfolio. Each solution is fully custom configured by HADES based on your project and mission requirements.
