Overview

RFeye DF is a flexible, cost-effective platform for remote broadband spectrum monitoring and geolocation of target transmitters of all types. Systems can be configured using a single RFeye node or multi-channel with the addition of further nodes. They are fully modular and single-channel systems can be upgraded to multi-channel for higher probability of signal intercept.

RFeye nodes are co-located with their antenna arrays and, for multi-channel systems, with each other. This tight coupling reduces cable runs and cable losses and significantly improves performance. Systems are compact and can be deployed in a vehicle roof box, on a mast or roof top. Multiple RFeye DF systems can be installed on a site, perimeter or border to detect and geo-locate the sources of suspicious signals.

Various DF techniques can be employed. The RFeye nodes may be individually synchronised to a GPS timing reference, or over a network connection using SyncLinc interface modules and distribution modules for improved accuracy. Once synchronised, all nodes sweep simultaneously for precise geo-location based on time difference of arrival (TDOA) or relative power on arrival (POA) at each receiver point, as well as sensing the angle of arrival (AOA) based on signal amplitude. Each technique can be used individually or all three can be overlaid for high probability geo-location.
