Why use radar satellite data?
•
•
•
•
Wide areas monitoring in short time (Approx 2-3 hours)
All weather conditions
No geographical limits
Operational cost reduction

Radar Satellite Data
SAR
• Perceive roughness/smoothness
• Perceive wetness/dryness
• Touch corners
Synthetic aperture radar (SAR) is a radar form used to
create two or three dimensional images of objects and
as a complement to the capabilities of photographic
imaging and other optical imaging because it is not
limited by daylight or atmospheric conditions and
because of the unique Response of terrain and cultural
targets against the radar frequency.
All Weather / All Time Operations
• Considerations about orbits and revisit (pros and
cons of Sun Synchronous)
• Same/different orbit plans
INDESO - KKP
Comparison of Optical and SAR Sensor
Electro-Optical
• reflected sunlight
• visible/infrared
• many channels
vs
SAR
- emits own radiation
- microwave
- one channel
• NO Phase information - phase information (coherent
detection)
• close to Nadir
• day time
• blocked by clouds

- day/night
- cloud penetrating

Oil Spill Visibility by SAR
Optimal wind conditions for oil detection by SAR:
Oil spill is detected by SAR as a dark area in contrast to the clean sea surface that is brighter.
However, for wind < 2 m/s:
background scattering is very low and most of the contrast between clean sea and oil is lost;
for wind > 14 m/s:
contrast is lost because (i) at the surface there’s a mixture of sea water and oil,
and (ii) with strong winds capillary waves form also for the sea water/oil
mixture.
Wind speed range for oil spill detection is 2 - 14 m/s.
The optimal wind speed range is 3 - 6 m/s

OIL SPILL DETECTION
Natuna, 22 Oktober 2016
1. There are oil spills from discharge a vessel : length
of oil is 38 km
2. The suspect vessel is Prosperity Tanker (Bakamla,
2016)
