Beyond direction finding – detecting and locating unauthorized, suspicious or interfering transmittersEnquire
The RFeye Array 300 is a fully integrated multi-mission system for continuous 24/7 spectrum monitoring and surveillance. It is designed to intercept signals, however transient, perform signals analysis and classification and quickly and reliably geo-locate target transmitters, all in real time. It is the smaller of the family of RFeye Arrays and is ideal for most critical site and border monitoring applications.
Class leading signal interception
RFeye Arrays use a unique multi-layer approach that is more sophisticated and versatile than traditional Direction Finding. Dual sinuous directional antenna modules are optimized for different frequency bands and arranged in multiple orientations. This makes the Array insensitive to the polarization of incoming signals, allowing it to reliably detect all types of signals, including those invisible to most DF systems that use linear polarized antennas.
Augmented geolocation techniques
The RFeye commutates at very high speed around the antennas to make near-simultaneous measurements in multiple directions. It measures correlations and calculates actual positional probabilities using “augmented” Time Difference of Arrival and/or Power on Arrival techniques. In addition, it gives a bearing (Angle of Arrival) based on received power at each antenna. Measurements can be overlaid onto a wide variety of 2D and 3D maps to give a unique positional display showing source geolocation probabilities, irrespective of signal power, bandwidth or frequency.
Modular and flexible deployments
The RFeye Array 300 is fully self-contained within a robust IP65 rated radome designed for hostile conditions. Close coupling of the RFeye node and antenna modules reduces cable runs and cable losses and significantly improves RF performance. Various directional antenna options are available from 300MHz to 18GHz and an RFeye Watson-Watt module is available for VHF transmissions down to 20MHz. The system is modular and further channels can be added to improve probability of intercept.
Advanced GUI provides easy multi-mission control including 24/7 continuous spectrum monitoring, programmable masks and alarms, signal analysis and optional signal classification capability.
