The threat spectrum is no longer predictable. Adversaries use frequency hopping and software-defined radio to operate in gaps that narrowband systems can't see. Here's what ultra-wideband drone detection changes.

Critical infrastructure has an airspace visibility gap. Drones can easily bypass ground-based security to survey, disrupt, and deliver payloads. Closing it requires passive RF detection, sensor fusion across RF, radar, and EO/IR, and pre-established drone defeat authority.

Modern drone threats have made the distinction between forward and rear operating areas obsolete. Persistent and passive ultra-wideband RF detection identifies drone presence from power-on, delivers line of bearing without a pre-loaded signal library, and provides the earliest actionable indicator in a layered C-UAS architecture. Periodic monitoring creates exploitable gaps. Persistent monitoring eliminates them.
