A400 series radar is the radar half of the AUDS system (Anti-UAV Defence System) — UK consortium kit deployed by US forces, monitoring the Korean DMZ and on the US southern border. AUDS detect-track-identify-defeat in ~15 seconds at up to 10 km. Also the B202 Mk 2 man-portable battery radar in transport backpacks for rapid deployment.
