Protecting Critical Infrastructure from Drones

Power plants. Water facilities. Data centers. These are the backbone of modern life—and increasingly, they're targets for surveillance and disruption by drones. As threats grow in both volume and sophistication, traditional perimeter security systems are being outflanked from above. It’s time to rethink how we secure critical assets. 

This is the core message in Echodyne’s white paper, Protecting Critical Infrastructure from Drones. The document explores how drone detection for critical infrastructure requires a new approach—one that includes advanced radar to provide real-time, persistent awareness of low-altitude airspace. 

Many current security architectures rely on a mix of optical cameras, RF sensors, and acoustic detectors. These tools have value, but they often fail to deliver complete coverage or real-time precision—especially in complex environments with noise, obstacles, or RF interference. 

• Emerging drone threats: Surveillance, payload delivery, and denial-of-service risks 

• Gaps in traditional systems: Line-of-sight limitations, latency, and false positives 

• Radar-based solutions: How 4D radar provides accurate, all-weather airspace awareness 

• Layered defense strategies: Integrating radar with optical, acoustic, and C-UAS systems 

• Use case insights: Real-world scenarios in energy, data, and transportation sectors 

Echodyne’s approach—featuring compact, tactical-grade radar—enables critical infrastructure operators to monitor their airspace with the same fidelity and persistence as their fences and gates.
