Security & Disaster Management

Drone Applications and Airspace Security

A key area of activity at Fraunhofer FHR is the radar-based detection, tracking, and classification of unmanned aerial vehicles (UAVs). The developed systems enable the reliable detection of even small drones over long distances and under challenging conditions, such as low visibility, adverse weather, or complex urban environments. Using high-resolution radar techniques and specialized signal processing, these systems not only determine position and trajectory but also analyze characteristic motion patterns. This enables the differentiation between various types of aerial objects and significantly reduces false alarms.

A particular focus is placed on integration into existing security architectures and on the fusion of multiple sensor data sources to generate a robust and comprehensive airspace situation picture. In addition to surveillance and counter-UAV applications, Fraunhofer FHR also investigates the potential of drones as sensor platforms—for example, for airborne reconnaissance, rapid situational assessment, and deployment in hard-to-access areas during disaster response scenarios.

Protection of Critical Infrastructure

Radar systems enable continuous, weather-independent monitoring of sensitive areas. Movements are precisely detected, objects are classified, and anomalies are identified at an early stage. This supports both perimeter protection and the monitoring of ground-based and aerial domains.

Support in Disaster Response

In disaster management scenarios, sensor systems demonstrate their strengths particularly under conditions of limited visibility or unstable structures. High-resolution localization techniques enable the detection of individuals, for example beneath debris or in smoke-filled environments. The combination of multiple sensing technologies enhances situational awareness and supports emergency responders in making faster and more informed decisions.

Development and Feasibility Assessment

At Fraunhofer FHR, the emphasis lies on application-oriented development—from initial concepts and feasibility studies to near-operational demonstrators. The primary objective is to design and validate sensor systems tailored to specific use cases. System design, sensor technology, and data processing are developed jointly and iteratively adapted to real operational conditions. Aspects such as mass production are not the primary focus; instead, efforts concentrate on developing robust, functional solutions for specific applications.

Collaboration for Application-Specific Solutions

In close collaboration with authorities, organizations, and research partners, customized solutions for safety-critical scenarios are developed. In addition to system development, rapid feasibility studies play a key role in evaluating the potential of radar-based sensing technologies at an early stage.
