Aerial Threat Detection and C-UAS

Fencepost™ Acoustic Surveillance System uses advanced acoustic sensors and multi-sensor integration to provide passive, real-time detection of low-signature aerial threats at low altitudes, giving forces the early warning and situational awareness to counter drones that evade traditional air defense systems.

FENCEPOST™ | DETECT. TRACK. COUNTER.

Fencepost is an interoperable Counter Unmanned Aerial System (C-UAS) that autonomously delivers reliable situational awareness against UAS Groups 1-3, including threats with low radar, infrared, or radio frequency signatures. Fencepost uses advanced acoustic sensors to identify small, autonomous, short-range UAS that evade traditional ground-based air defenses to support real-time informed decision-making across challenging terrain and contested environments.

Long Range Maneuvering Projectile (LRMP)

Fencepost is lightweight, modular and rugged with a rapidly deployable base station for easy setup and quick small unit protection in challenging and contested environments. The system’s low price per unit provides a cost-effective solution to expanded coverage.

FEATURES

  • Passive situational awareness: Detect low-signature autonomous aerial threats without revealing location.
  • Directional tracking: Monitor targets and pinpoint direction-of-arrival while suppressing and canceling loud, stationary noise sources.
  • Smart filtering: Reduce false alarms and filter out non-threats, ensuring actionable alerts from continuous detection algorithms.
  • Advanced signal classification: Extract eigenvector‑based features in real‑time for accurate target classification with signal processing and prioritization.
  • Seamless command‑and‑control integration: Connect instantly with existing platforms to streamline operations and support tactical decision-making.
  • Scalable detection footprint: Customize perimeter ranges and meet mission-specific, multi-sensor coverage needs at a low price per unit for a cost-effective solution to expanded coverage.

COMPATIBILITY

Users benefit from comprehensive tracking and visualization features, including early warning alerts with target bearings, simultaneous multi-threat tracking, and 3D target visualization. Captured data integrates easily with existing C2 software, supporting intelligence, surveillance and reconnaissance (ISR) operations, and decision-making applications. Integration enables Fencepost to quickly deliver location sharing data directly from sensors to fire support systems, using specialized messaging formats designed to confirm data is valid.

Fencepost provides critical protection against the growing threat of UAS Groups 1, 2, and 3, which often evade traditional detection methods and pose significant risks to ground forces and vital assets. Validated to defend against both fixed- and rotary-wing, autonomous, and short-range UAS, Fencepost safeguards maneuvering forces, installations, and other high-value targets.

Its advanced detection and tracking capabilities fill a vital gap in air defense, ensuring reliable protection against emerging aerial threats that challenge conventional security measures.
