Sentinel C-UAS Solution
The Sentinel is an advanced counter-UAS (C-UAS) solution that combines a swarm of networked, European-made UAVs with active radar technology to deliver superior detection and interception capabilities. Unlike traditional ground-based systems, Sentinel provides an unobstructed line of sight, significantly enhancing situational awareness and threat engagement.
A single operator can rapidly deploy multiple mesh-networked UAVs, each equipped with active radar and optional EO/IR sensors. By leveraging a swarm architecture, Sentinel creates a 360-degree detection bubble, with each UAV covering its own sector while collectively ensuring full coverage. This approach provides early warning against airborne and ground-based threats, enabling interception at a stand-off distance. The system can seamlessly integrate with command and control (C2) networks, as well as kinetic and non-kinetic effectors, ensuring interoperability with existing defense systems.
Sentinel’s resilient architecture allows it to operate effectively in GNSS- and communications-denied environments, making it highly reliable in contested battlefields. Unlike traditional radar solutions, Sentinel’s active radar does not disclose the operator’s location, maintaining operational security.
Onboard edge AI processing enables real-time sensor correlation across the swarm, ensuring accurate target discrimination while minimizing bandwidth usage. Sentinel can effectively distinguish UAS and ground-based targets from background clutter such as birds, debris, and structures. It tracks multiple threats simultaneously, with target limits defined by spacing, radar cross-section, and kinematic distinguishability. Configurable thresholds prevent system saturation in high-density threat environments.
Additionally, Sentinel’s adaptive AI dynamically prioritizes high-confidence targets, reallocating sensor resources as needed to maintain operational integrity. Target trajectory analysis enables hostile intent prediction and effective intercept point calculation, significantly enhancing threat response.
Applications
- Mobile Convoy Protection: Deployable in just 20 minutes, Sentinel safeguards convoy routes in challenging environments such as urban and mountainous regions.
- Fixed-Site Defense: With endurance of up to 72 hours via battery swaps, Sentinel provides continuous overwatch for military bases, camps, and forward operating posts.
- Critical Infrastructure Security: Ideal for urban and complex environments, Sentinel protects vital assets such as power plants, airports, harbors, and utilities from potential threats.
- Border Patrol: With long-range and long-endurance capabilities, Sentinel monitors extensive borders to prevent smuggling and other security risks.
By leveraging advanced radar, AI-driven processing, and an adaptive swarm-based approach, Sentinel redefines counter-UAS operations, delivering an impressive defense solution against emerging aerial and ground-based threats.
