RFeye Array overview

The RFeye Array is an ultra-wide frequency, multi-mission system for fixed or mobile applications with simultaneous direction finding (DF), spectrum monitoring, and geolocation capability. It houses one or two RFeye Nodes, directional antennas, and omnidirectional antennas in a robust radome, designed for hostile environments. Operating up to 40 GHz, you are unlikely to ever miss a signal of interest.

With broad bandwidth and high sensitivity, the RFeye Array is equipped with inbuilt processing capabilities for efficient geolocation and monitoring, which reduces the need for extensive backhaul data. Additionally, its unique architecture permits multiple simultaneous tasks and missions, supporting diverse operational needs.

RFeye Arrays are available in several sizes and configurations; however, all models are designed to provide hybrid capability, allowing combinations of PoA, AoA, and TDoA techniques to be used against signals for optimal suitability.

Deploying your hardware

RFeye Arrays are built in a range of sizes and antenna configurations. They can be mounted in fixed positions on towers, masts, and buildings or on mobile applications such as vehicles or trailers.

Each RFeye Array is housed within a robust IP55-rated radome designed for hostile conditions. Additionally, the RFeye Array can be used as a standalone system or networked over large distances with other RFeye systems as part of a wide area spectrum monitoring and TDoA system.

A more sophisticated & versatile approach to DF

The RFeye Array uses a unique multi-layer approach that is more sophisticated and versatile than traditional direction-finding techniques.

Spiral directional antennas

High-performance spiral directional antennas are optimized for different frequency bands and arranged in multiple orientations. The spiral antennas support a high-speed commutating approach, whereby an RF receiver scans from 300 MHz to up to 40 GHz. This allows for swift and accurate direction finding or signal characterization as the receiver measures correlations and calculates actual positional probabilities based on received power at each antenna.

Signal polarizations

The Array is sensitive to most incoming signal polarizations, including all linear polarizations, allowing reliable detection of signals, including those invisible to other DF systems. Also, timing and synchronization features enable combined AoA, TDoA, and PoA techniques. Irrespective of signal power, bandwidth, or frequency, these techniques allow all signal types in the range to 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.

Accuracy ensured

Each RFeye Array undergoes individual calibration in real-world settings to ensure its accuracy. It then retains a constant, unique calibration file, eliminating the need for frequent recalibrations. This design guarantees sustained accuracy, even in extreme environmental conditions, offering reliable performance without the maintenance hassle.
