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.
