Surveillance and Observation Radar (SAR - Synthetic Aperture Radar)

Applications

 > Environment & Oceanography

• Pollution detection (ground and sea).
• Bathymetry and measuring of sea currents.
• Cartography of terrestrial scenes, change detection.
• Ice layer monitoring.

 >  Agronomy & Forestry

• Vegetation, harvest & forest monitoring from satellite .
• Biomass monitoring.

 >  Defense & Security

• Target detection, identification & localization

• Airborne reconnaissance & surveillance, GMTI (Ground Moving Target Indication)
• Maritime traffic surveillance
• Disaster monitoring .

Keywords

• Radar, SAR, Signal processing, Image processing, DRI, Localisation

Advantages

• Largest range of state of the art SAR sensors in Europe.
• Unique combination of advanced hardware technology and signal/image processing.
• Multiple connections with European Research Establishments to conduct innovative studies with state of the art experimental facilities.

Testing

• Remote sensing with polarimetric, interferometric high resolution radar imagery:
  • A large range of possible host platforms (aircrafts, helicopters, UAVs) dedicated to military, civil or dual applications carrying various radars sensors from 400 MHz to 95GHz, with X-track interferometric (3D imaging), Along-track interferometric (ATI) and polarimetric capabilities at high resolution (less than 0.5m).
  • Combined use of electro-optical sensors (visible and infrared domains) for richer multi spectral information and a more robust intelligence gathering.

Expertise

• Multiple data acquisition campaigns and image analysis
• Over 15 years of experience in:
  • HF to EHF sensors development
  • SAR processing, innovative digitally generated waveforms
  • Design & realisation of integrated system (platforms + sensors + exploitation)
  • Image interpretation
