The Ku-band Radio Frequency System is a 360-degree radar that senses incoming drones, rockets, artillery and mortars.
It can cue defensive weapons, and it can be set up within 30 minutes, either in a fixed location or on a vehicle.
Raytheon built the KuRFS radar to help the U.S. Army defend against rocket, artillery and mortar attacks in Iraq and Afghanistan. Today, it is also used as a counter-unmanned aerial system radar. It works with multiple weapons systems including the land-based Phalanx Weapon System, 50-caliber guns and 30 mm cannons. The radar also supports the High Energy Laser and the Coyote weapon system.
KuRFS uses a radar sensing technique called active electronically scanned array, which uses many small antennas, rather than a single powerful antenna, to allow for better control of the beam. It operates in the Ku-band of the electromagnetic spectrum, which allows for higher-resolution imaging – an important part of tracking smaller flying objects.
Birds, planes, drones – KuRFS radar can spot them all
