Flying drones can be fun. For RC and photography enthusiasts, a drone is a source of entertainment, and with a camera attached, provides breathtaking birds-eye views. For commercial and first responder purposes, a drone can be a valuable asset for information and increase productivity. However, when a drone is operating where it shouldn’t, the potential ramifications can be catastrophic and costly. For these situations, organizations need real-time, accurate, simple to operate and cost-effective solutions for detecting drones flying in or near restricted airspace. In this application note, we’ll discuss the basics for detecting a drone with a Real-Time Spectrum Analyzer and how networking multiple Spectrum Analyzers together can create an automated drone detection system with 24/7 monitoring capabilities.
