Layered Defense Architecture
No single device defends anything. Systems do. This is the anatomy of one — the same pattern behind every solution page on this site.
The rings
-
01
Ring 1 — wide-area detection (outer)
Radar and spectrum monitoring sweep the entire approach volume, out to 5–10 km depending on terrain. Everything that flies, floats or crawls enters the air picture with kinematics and emitter classification.
-
02
Ring 2 — identification (middle)
Cued EO/IR acquires the contact: AI classifies drone versus bird versus aircraft, the laser rangefinder fixes 3D coordinates to fire-control grade, and the video becomes evidence.
-
03
Ring 3 — mitigation (inner)
Only now do effectors enter: standoff jamming, net capture, or — in military-class architectures only — directed energy. Every action is authorized, logged and reversible where possible.
-
04
The command layer (all rings)
GIS-based air picture, threat grading, remote device control, alert stages, evidence archive and debrief replay. Standard interfaces (Ethernet/UDP/RTSP) keep it integrable with whatever security stack already exists.
The cueing chain, in one breath
Radar finds at 6–10 km; spectrum classifies the emission and starts localizing the pilot; EO confirms visually and starts the evidence chain; the operator — or the standing rule set — decides; the effector acts for seconds; assessment records the outcome. Total decision time can be under a minute from first detection, because each link was ready before the target arrived.
Design the rings to fail soft: if radar is jammed, EO and spectrum carry detection degraded; if EO is blinded by weather, radar and RF hold the track. Redundancy across principles is the entire point of layering.
