Applications for Synthetic Aperture Radar (SAR)

        SAR has now become one of the valued remote sensing tools for both soldierly and noncombatant users. Various soldierly SAR applications are intelligence gathering, battlefield survey, and weapons supervision. The noncombatant applications include topographic planning, geology and mining, oil spill observation, sea ice observation, oceanography, agricultural and land-use monitoring, and planetary or celestial examinations. The observation and interpretation of the earth using SAR have the following wide practical applications as discussed below.

On the ocean

  • Man-made illegal or accidental spills are visible in SAR images.
  • Ships can be detected and tracked.
  • Natural leakage from oil deposits can also be observed, providing hints for the oil industries.
  • Scientists are studying the radar backscatter from the ocean surface which is related to wind and current fronts, eddies, and internal waves.
  • In shallow waters SAR imagery allows one to infer the bottom topography.
  • The topography of the ocean floor can be mapped using the very precise ERS Altimeter because the sea bottom relief is reflected on the surface by small variations of the sea surface height.
  • Ocean wave forecasting and marine climatology.
  • Regional ice monitoring. This is essential for navigation in ice-infested waters.

On the land

  • Monitoring lands of forestry and agriculture.
  • Some geological or geomorphological features are enhanced in radar images thanks to the oblique viewing of the sensor and to its ability to penetrate (to a certain extent) the vegetation cover.
  • SAR data can be used to georeference other satellite imagery to high precision, and to update thematic maps more frequently and cost-effectively, due to its availability regardless of weather conditions.
  • In the aftermath of a flood, the ability of SAR to penetrate clouds is extremely useful. Here SAR data can help to optimize response initiatives and to assess damages.
  • Detection of small surface movements caused by earthquakes, landslides or glacier advancement.
