Drone detection

CRFS passive RF signal hunting technology allows users to accurately detect and geolocate COTS, modified, and military drones  

Overview

C-UAS comprise a series of sensors that deliver data into a C2 platform. The RF sensor capability of a C-UAS is the foundation upon which it is built, allowing the system to identify and discriminate drones from other targets and signals.

Standard C-UAS employ SDRs that only operate in the IMS bands; while adequate for detecting COTS drones, they are insufficient to detect a broad range of threat vectors, including MALE and modified drones. Wide spectrum capability is vital to identify and address all threats.    

CRFS’ RFeye technology detects every type of UAV that emits an RF signal. Our signal detectors hunt for RF signals of interest rather than drones—a more powerful and precise capability. When the system detects a specific signal, it immediately performs a 3D geolocation—providing real-time intelligence displayed on screen or delivered to your C2 system. Our drone detection technology can detect military drones at high altitude. It is TRL-9, has been integrated into systems built by L3Harris and Rafael, and is currently operational in many allied countries across the globe.

Drone detection applications

Drone-defense-icon
Operates on military & commercial drones

Wide frequency capability is critical to detecting MALE, COTS, and modified drones operating on frequency bands from 100 MHz to above 10 GHz.

RF-recording-icon
Integrated into leading C-UAS

CRFS RF sensors are integrated into globally renowned C-UAS, including L3Harris Drone Guardian and Rafael's Drone Dome.

Additional full spectrum monitoring capability

Users are not limited to solely detecting drones with CRFS' RF receiver network; the system can also be used to monitor all RF traffic around the installed location.

100-POI-signal
Detect the signal of interest, not the drone

Open-ended signal detectors search for specific signals (including telemetry, video links, payload data transfer) rather than for individual drones—a more intelligent and effective approach to drone detection. 

boarder-icon
Low false positives

Signal detectors are designed to generate low false positives, and CRFS software has additional filtering capability to add an extra layer of security, eliminating false positives.  

wireless-icon
High operating range

Employing a mixture of standard omnidirectional antenna systems and higher gain antennas, CRFS technology extends the operating range of RF systems when detecting COTS drones operating with low power.  

drone-icon
Detect drone swarms

Advanced RF systems have rapid geolocation detection cycles, allowing the detection of multiple commercial or modified drones with refresh speeds of once per second.
