Layered, networked sensor architecture for counter-UAS detection

The article describes an evolving counter-UAS approach emphasizing networked, layered sensing (radar bands plus EO/IR, acoustic, and EW sensors) and physically distributed/elevated sensor placement to reduce blind spots and improve reaction time against small, fast, low-altitude and swarming drones. It also references Leonardo DRS expeditionary radar kit concepts (e.g., 202 Expeditionary Skid / multi-mission hemispheric radar) as part of this integrated architecture.
