Wideband RF spectrum streaming, recording and analysis

The SenS range of spectrum recorders are designed for the operator who needs to capture and analyze signals in high fidelity across a wide frequency range. RFeye SenS allows operators to capture intermittent, low-power and short-duration signals, even if these signals occur outside of working hours or hide next to other transmission sources. SenS captures the spectrum in extremely high resolution. It can continuously stream full-rate I/Q over the selected bandwidth to storage media, meaning you never miss a signal.

Each SenS receiver provides a frequency range of up to 8GHz or 18 GHz and a 100-MHz IBW. Multiple receivers can combine seamlessly to provide an IBW up to 1GHz without the loss of Spurious Free Dynamic Range (SFDR) that usually affects very wideband receivers. This means SenS captures and records data with a much higher level of fidelity than can be achieved by other systems.

Data analysis can be performed in situ or remotely using the DeepView software. DeepView is designed for rapid search through multi-terabyte I/Q datasets for signals of interest, enabling very large datasets to be analyzed in minutes.

Use cases

Radar testing and analysis

EW/radar testing and analysis

Many radar systems try to disguise their signals by randomizing and spreading the pulses over a wide bandwidth. Using RFeye SenS to capture the full I/Q over a wide bandwidth allows an analyst to discriminate an individual radar pulse from the background noise. In the design and test of radar systems, this capability is also extremely useful to help ensure the system is performing to specification.


Post-event analysis and testing

After a test has been completed, you may need to question what exactly happened in the spectrum over that period. Did anything occur that caused interference to your systems? Were there any unexpected signals or anomalies? By recording the full I/Q you can reconstruct what happened and when. This data can then be used to verify the root cause or create repeatable environments for further tests, saving you time and money.

Interference hunting

Interference hunting

When radar or other transmissions cause accidental interference to communications equipment, spectrum managers and enforcement teams need to be able to identify the source quickly and with certainty. However, this can be difficult when the signal is sporadic or transient. By capturing the full I/Q you can quickly find trends and patterns in the data over time, which will help identify the signal source.

Signals intelligence

Signals intelligence (SIGINT)

Military and security services are interested in a range of signal types generated by hostile actors. By recording and analyzing the spectrum over time, it is possible to determine what signals were generated and where they came from. Further decoding and classification work can then be performed to extract evidential intelligence from the captured signals.
