Spot that drone!
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.
