The German RF manufacturer Aaronia has developed a system for detecting drones and other RF signal sources in the frequency range of 9 kHz to 20 GHz at distances up to more than a kilometer. The system combines the Aaronia IsoLOG 3D tracking antenna with the remotely controllable Spectran V5 real-time spectrum analyzer and a new plugin for the RTSA Suite software package.
 
Each sector of the antenna generate a real-time view of detected RF sources in its field of view, derived from frequency and power measurements. All of this data is combined to created a full panoramic view, including an image or live video of the surroundings. This gives the user a full picture of all RF sources present in the vicinity of the detection system. The system can generate a visual or acoustic alarm when defined limits are exceeded.
 
The tumultuous growth in micro and mini unmanned air vehicles (UAVs) creates a constantly increasing security threat for companies, government organizations and military bodies. Drones are inexpensive, easy to operate and hard to detect, which makes them difficult to defend against. With the new Aaronia system, drones can be detected quickly and precisely, even if they are flying between buildings or trees.
