Ranger R3D Radar

Dual Mode Perimeter Surveillance Radar

The FLIR Ranger R3D Radar 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 slowmoving threats such as walkers and crawlers.

A COTS unit for detecting and tracking surface movement, R3D provides wide area detection when used as a cueing device. Operators can be confident of up to 128 threats at a time due to low false alarm rates. Network with other FLIR radars to create an overlapping array that protects larger areas such as borders, ports, airports, and military bases. Target information output includes ID, location, range, bearing, latitude, longitude, confidence level, heading, speed, and time.


Ranger R3D Doppler provides extended range coverage in almost any terrain. Overcome blind target ranges/velocities by switching to Fast Scan/FMCW.

Switch between Fast Scan and Doppler depending on terrain and recognition requirements. Enhanced performance supports both radial and tangential detection.

Network multiple FLIR radars and EO/IR imagers with FLIR command and control to form a single powerful, integrated surveillance system.

R3D quickly detects up to 128 threats simultaneously while accurately displaying each target’s location.

Designed for permanent, all-weather installations and mobile, stop-and-scan operations, R3D can detect pedestrians, crawlers, and vehicles in virtually any environment.
