Tactical direction finding
The DFH18 is a Compact Direction-Finding Head operating from 500MHz to 18GHz. It combines high-precision direction-finding (AoA) with wideband spectrum monitoring 2D/3D TDoA in a rugged, tactical format.
Overview
The DFH18 Direction Finding antenna is a robust, field-ready solution for real-time 500MHz–18GHz line-of-bearing (LOB) with a typical DF accuracy of less than 2.5° RMS. It is compatible with the RFeye Node 100-18 and RFeye Node 100-40 and can be attached to any existing RFeye Node.
Six high-performance spiral antennas with high-speed commutation and precise timing enable synchronized data correlation across multiple DF Heads and RFeye Nodes, delivering accurate geolocation of target signals using combined AoA and TDoA techniques.
LOBs can be overlaid onto a wide variety of maps, satellite images, and 2D / 3D GIS datasets to give a unique positional display showing source geolocation probabilities. All signal types in the range can be mapped, irrespective of signal power, bandwidth, or frequency.
Lightweight (7.5kg) and rapidly deployable, the DFH18 can be fully integrated into CRFS sensor networks and software ecosystems. Ideal for electromagnetic operations, border security, interference hunting, and wideband UHF/SHF/EHF COMINT/SIGINT operations.
CRFS offers a selection of interchangeable DF Heads designed for use with Rapid Deployment Kits (RDKs), allowing users to build a toolkit suited to each mission.

Run multiple missions (geolocation, detection, measurement missions etc) in parallel for maximum flexibility. Spectrum monitoring & measurements Conduct ITU-compliant spectrum monitoring and all essential measurements including channel occupancy, power, and frequency deviation. Overlay and analyze with customizable charts and measurement tools. Signal Discovery Signal Discovery increases probability of intercept for hard-to-find, unknown signals, or signals hidden in the noise. It is especially useful to discover non-standard signals, drone telemetry and datalinks, and mesh modems, which help identify mesh networks. Fast, accurate geolocation Manually or automatically detect signals of interest and geolocate the source by using multiple geolocation techniques. Time Difference Of Arrival (TDoA), Power On Arrival (PoA), Angle Of Arrival (AoA) techniques are all supported as well as hybrid geolocation which combines all of them, displayed within the interactive map. Geolocate multiple targets over wide areas in real-time with extremely fast update rates ensuring accurate geolocation of emissions even from fast-moving targets. Hybrid geolocation draws on powerful algorithms, fast and accurate synchronised techniques (AoA, TDoA and PoA) for advanced localization and geolocation. The post-processing TDoA feature allows geolocation of recorded signals allowing, for example, post-event diagnosis of interference incidents. Geolocation scenarios can be conducted with the simulation tool enabling users to practice and fine-tune their geolocation and interference-hunting skills.
