Ranger R3D

Long-Range Perimeter Surveillance Doppler Radar

View Datasheet > Ranger R3D


The Ranger R3D is a dual mode, ground surveillance radar designed to provide efficient, 24/7 persistent surveillance, both within and beyond the fence. Operating in the Ka-band, the Ranger R3D leverages the resolution and accuracy of advanced FMCW technology and the extended range and terrain adaptability of Doppler in a single, compact, and lightweight package. Ruggedized for permanent, all-weather installations and mobile, stop-and-scan operations, its low minimum detection velocity (MDV) detects slow-moving threats such as walkers and crawlers.
