Ready to Deploy

SPECTRA systems are deployed and supported worldwide in over 30 countries, backed by a UK-based support and service team available year-round to support our customer’s most important operations

Super Resolution DF

CommsAudit’s Super-Resolution DF (SRDF) processing enables prosecution of co-channel and short duration signals, critical enablers in a congested, contested electromagnetic environment

Modular and Adaptable

The SPECTRA family of DF systems is inherently modular, and can be tailored to a specific requirement or mission profile.

The SPECTRA SRDF system is no different, and various antenna and DF processing form-factors can be combined to create a system suitable for fixed-site install, land/maritime platform operations or portable use

Designed for a congested, contested environment

Future EW operations are expected to be undertaken in a congested and contested electromagnetic environment. These broad terms imply two specific challenges for EW sensors, principally, dynamic range and co-channel interference.

Co-channel interference (i.e. more than two signals occupying the same frequency at the same time) is a condition under which simple DF processing (e.g. Watson-Watt, two-channel Correlative interferometric) techniques fail.

CommsAudit’s super resolution processing is designed to deliver reliable direction-finding results in the presence of co-channel interference. Additionally, it makes provision for dynamic spatial filtering (by beam-forming and null-steering) of wanted/unwanted emissions, enabling successful collection of SOI under co-channel conditions. The multi-channel architecture enables prosecution of multiple SOI in parallel, each with independently configured beam/null configurations.

A further benefit of the CommsAudit’s Super Resolution system architecture is superior detection & DF of short duration signals. Each antenna element is a sampled continuously without switching or sequencing. This approach yields superior POI for short duration emissions e.g. high rate frequency hopping signals or burst signals. CommsAudit has previously demonstrated single-digit micro second (µS) detection and DF with pulse widths in the region 7-9 µS.
