Teledyne FLIR has upgraded its Ranger counter-UAS (unmanned aircraft system) software to include a new Fast-Scan technology feature designed to improve detection and tracking performance against increasingly agile drone threats. The enhancement aims to boost situational awareness and responsiveness in layered airspace defence systems.
The Ranger software suite serves as a central processing and management tool that correlates data from multiple sensors such as radar, electro-optical/infrared (EO/IR) cameras and radio frequency (RF) detectors. With the addition of Fast-Scan, the system can process sensor data more rapidly and update target tracks with greater frequency, enabling faster recognition of fast-moving or low-observable unmanned aerial systems.
Fast-Scan technology works by increasing the refresh rate of sensor feeds and algorithmic processing loops, allowing operators to see changes in the airspace picture almost in real time. This is particularly valuable in environments where drones may manoeuvre unpredictably or operate at varying speeds and altitudes. By rapidly refreshing tracks and threat assessments, the upgraded software assists operators in making quicker engagement decisions.
The enhancement also improves the integration between sensor types. When radar detects an airborne contact, the software’s increased processing speed enables quicker handoff to EO/IR cameras or RF systems for classification and identification. This tight integration supports faster cueing of selected effectors or mitigation tools, improving overall effectiveness in counter-UAS operations.
Teledyne FLIR says the upgrade is compatible with existing Ranger installations, allowing users to benefit from the new capability without significant changes to hardware infrastructure. The updated software can be deployed via field updates, providing Defence, homeland security and critical infrastructure customers with an immediate performance uplift.
The introduction of Fast-Scan comes amid growing demand for more agile and responsive counter-drone systems, as small unmanned aircraft become more accessible and manoeuvrable. Defence and security organisations are under increasing pressure to detect and respond to diverse threat profiles, ranging from commercial off-the-shelf drones to sophisticated custom UAVs.
By enhancing the Ranger platform with faster data processing and improved sensor fusion, Teledyne FLIR aims to help users maintain airspace awareness and rapid reaction capability. The upgrade supports layered defence strategies where accurate detection, tracking and identification are foundational for effective counter-UAS engagements across military and civilian operational contexts.
