Automated Drone Detection System

OBSIDIAN, our counter drone technology, is specifically designed to detect, identify and track small/micro drones.

The growth of the civil drone market has resulted in criminal entities increasingly utilizing low cost Unmanned Aerial Vehicles (UAVs) to threaten Critical National Infrastructure, prisons and other sensitive sites where traditional security measures are easily defeated. These small and extremely agile platforms can be used to deliver contraband, capture intelligence, and potentially deploy explosives without detection.

The use of drone technology has resulted in an increasing demand for reliable counter-UAV systems to detect, identify and defeat them.

Low-cost 3D radar is a long-term solution. Radio Frequency (RF) techniques are already being overcome by pre-programed flight plans; acoustic sensors may not provide sufficient range or may experience audio interference, and cameras need to be cued on to a target. The single most reliable signature that a small UAV possesses is its physical presence and the rotors, which are used for flight, which are exploitable by radar systems.

OBSIDIAN provides a 180° Azimuth by 85° Elevation staring antenna array that overcomes the limitations of competing systems, which typically have less than half this coverage and use mechanical or electrical scanning, often resulting in missed targets. OBSIDIAN also uses novel techniques to recognize drone features to avoid misclassification of birds and wildlife.

OBSIDIAN has been developed from the highly capable Military Alarm radar, used by the British Army to provide warning of short-range aerial target attacks with >99% probability of detection and less than one false alarm per week.

Intuitive threat warning interface

Our Palisade® Surveillance Management System provides a cost-effective control-room solution that requires minimal manning due to its automated threat alarm and supporting integration with existing security systems, giving a seamless and coherent operation.

Palisade® assesses threat tracks from the OBSIDIAN radar in real-time, classifies detected drones, and automatically cross-cues the camera in 3D to accurately zoom onto the target of interest. Video clips are automatically tagged to tracks on the Palisade GUI, automatically generating alerts. This functionality is designed to be easily integrated into an existing security system.

Palisade® employs advanced, patented tracking and fusion algorithms which turn raw sensor outputs into robust tracks and alerts. Intuitive, uncluttered displays enable operators to react to alerts with minimal effort.

Key benefits

  • Fully automated – operators can respond directly to alerts or they can set the system to automatically cue an effector. It provides minimal false alarms.
  • Low cost – due to its PCB-based design.
  • Portable – a small and lightweight solution that can be mounted on a tripod, a vehicle, a mast or directly onto the side of a building.
  • Speed and accuracy – can detect drones as soon as they enter a monitored area, distinguishing them from other flying objects, and track slow moving and stationary drones.
  • Extensible – virtually any sensor and/or effector can be controlled by Palisade™ and provided as a total counter-drone solution.
