RFeye Array 300 series overview

The Array 300 is a spectrum monitoring and direction-finding system for mobile or fixed deployment. It provides 100 MHz IBW and is available in three different receiver configurations, offering spectrum monitoring up to 8, 18, or 40 GHz. Each Array contains two RFeye Nodes to allow users to carry out multiple missions simultaneously. These RF sensors are closely connected to the antennas for maximum sensitivity.

The Array 300 uses a unique multi-layer approach that is more sophisticated and versatile than traditional direction finding. It uses the Watson-Watt methodology for signals between 20 MHz and 300 MHz in addition to high-performance directional spiral antennas that reject interference and multipath and are optimized for different frequency bands. These spiral antennas are sensitive to most incoming signal polarizations, including all linear polarizations. This means the Array 300 can detect signals that are invisible to most DF systems. Also, the Array’s timing and synchronization features enable combined PoA, AoA, and TDoA techniques, allowing all signal types in the range to be mapped, irrespective of signal power, bandwidth, or frequency.

Principles of
geolocation
techniques

This white paper describes the underlying principles of geolocation techniques (AoA, TDOA, FDOA, & PoA) and outlines their applications. 

WP-Passive-Geolocation
Passive geolocation
with 3D TDOA

Learn about the passive technique known as Time Difference of Arrival (TDOA), which uses the time difference between receipt of signals at spatially separated receivers to determine the location of the source.

WP-Cover-AoA
Angle of arrival / direction finding techniques

This white paper outlines the various forms of AoA , including how they work, how they can be applied in practice, and how they can be combined with other geolocation techniques, such as time difference of arrival (TDoA).
