Rumore
RUMORE provides intelligence on Radio Frequency Emitters, including their location and waveform. These are extracted from Synthetic Aperture Radar (SAR) images by RUMORE. The waveforms can be matched and identified with a radar emitter database (REDB) of known transmitter types, within in the same spectral domain. Signals generated by ground transmitters are typically considered as Interferences that degrade the quality of the SAR data, hence as far as possible removed. RUMORE focuses on the information content that can be derived from such signals, when properly identified and characterized.

Who needs it
Organisations that can benefit from Rumore




What can it detect
Detect and Identify a wide array of RF systems in C-, X-, L-, P- and K-Band






























































Frequency Band: C-Band
-
Frequency Range: 4 to 8 GHz
-
Typical Systems: Weather Radars, Shipborne Radars, Port Radars
-
Applications Weather: forecasting, air defense, maritime surveillance.

Weather Radars
Used for meteorological observation, precipitation tracking, and severe weather forecasting. Provides a balance between range and resolution.
e.g. NEXRAD (Next-Generation Radar, USA)

Long-range Surveillance Radars
Shipborne radar used for air and missile defense, providing tracking and detection of aerial threats. Often installed on naval vessels for maritime defense.
e.g. AN/SPY-1 (Aegis Combat System Radar)

Port Radars
Used in harbor and port operations for vessel tracking, collision avoidance, and safe navigation. C Band is ideal due to minimal interference from rain.
e.g. SCANTER 2001
Which SAR systems are supported
Spaceborne SAR
Passive SAR
Airborne SAR
Rumore operates effectively across all SAR bands, including C, X, L, P, and Ka. Its capability has been successfully demonstrated with data from various platforms, such as:ALOS PALSAR (L-Band)Sentinel-1 (C-Band)Capella (X-Band)COSMO-SkyMed (X-Band)By combining data from multiple providers within the same frequency band, Rumore enhances geolocation accuracy. Additionally, using different frequency bands helps to uncover more detailed insights on cross-band emitters and identify various types of RF emitters.​
Rumore is not limited to active SAR systems, where targets are illuminated by a radar sensor. It also supports passive SAR data acquisition, where it has been successfully demonstrated in the X-Band. This technology is particularly advantageous for edge deployment. Passive SAR RF data capture holds significant future potential, as it allows for continuous monitoring of RF emitters worldwide without degrading the SAR system's performance or incurring significant costs to satellite operators.
Rumore already supports
Rumore can analyze RF interference in airborne SAR systems and is designed for deployment at the edge, allowing for flexible and in-flight processing.
