Electronic Warfare Support and Signal Intelligence (SIGINT)


Achieving information superiority is vital for military decision making. The increasingly complex electromagnetic spectrum is a key source of information for both strategic and tactical intelligence. SIGINT, from either communication systems (communications intelligence – COMINT) or electronic signals from non-communications signals (electronic intelligence – ELINT) has developed at a rapid pace over the last few years.

But it is more than demodulating and decoding radio conversations. Today’s challenge also lays in how to effectively extract, classify and locate transmissions within the spectrum. CRFS works with militaries and systems integrators to provide key components of SIGINT and ELINT solutions. The high performance, durable and reliable RFeye Nodes and Arrays can pick up a wide range of signal types from many kilometers away, even low powered, pulsed signals. Using our Artificial Intelligence system, these signals can be classified as friend, foe and the type of equipment, and then geolocated to gain intelligence on who, what and where the signal came from.

Strategic use

By monitoring the utilization of emitters commanders can make strategic decisions on opposing force intent. For example, by analyzing the usage and locations of radar and communication systems, enemy troop movements and capabilities (e.g. the weapons systems associated with a radar system) can be calculated and used to develop any future offensive or defensive operations.


Tactical use

With real-time spectrum intelligence, troops on the ground can be instantly aware of any potential threat. CRFS systems can monitor and alert friendly forces to the presence and location of enemy forces in their immediate vicinity. By being forewarned, they are then better able to prioritize and respond to potential threats in real time. For example, radio transmissions located in an upcoming valley could indicate a possible enemy ambush site.

Analyze radar signalsAnalyzing enemy radars

As well as detecting the presence of a radar, the RFeye systems can be used to gain intelligence on the equipment and characteristics. By recording and analyzing an enemy radar signal: the type of radiation, its modulation, its pulse rate/duration, pulse shape, its radio frequency etc., the radar can be identified and compared with known signal types. This can then be used to determine its range, use, capability and vulnerability to countermeasures.


RFeye Nodes and Arrays can be deployed in both fixed and mobile configurations to operate stand-alone or as part of a spectrum monitoring network. With optimal SWaP considerations integrated into the design, they form a rugged, reliable source of spectrum intelligence. See our deployment options.
