Maritime Surveillance

Ice and iceberg monitoring

User Requirements Expected Results and
SAR Capabilities
  • Ice Concentration
  • Stage of development
  • Floe size
  • Ridging
  • Ice Strength
  • Assuring safe and efficient maritime navigation in hazardous ice conditions.
  • Improved Weather Forecast.
  • Supporting Canada's multi-billion maritime trade and northern sovereignty.

"RADARSAT data has proven to be a very cost-effective way of monitoring ice conditions throughout Canadian waters and has enabled us to expand our service and reduce the CIS budgets by about $6 million dollars a year in terms of data acquisition."

B. Ramsay, CIS

Marine winds

User Requirements Expected Results and
SAR Capabilities

Frequent and high-resolution near-surface wind information.

  • Improving weather forecasting and warning systems.
  • Support to marine operations.
  • Site selection for wind farms, oil spill drift information, search and rescue support.

Oil Pollution Monitoring

User Requirements Expected Results and
SAR Capabilities
  • Detection and mapping of oil spills with minimum width of 100 m.
  • Detection and positioning of adjacent ships within the same surveillance swath.
  • Concurrent estimates of surface wind vector over ocean.
  • Near real-time reports on oil spills.
  • Improving Canada's response to the monitoring, containment and clean-up of oil spills.
  • Contributing to surveillance efforts of ISTOP.
  • Protection of sensitive coastal zone from environmental pollution.

"Availability of RADARSAT-1 data is the biggest technological blessing to the peaople to counter this large scale disaster."

Makoto Higashi, General Manager, Remote Sensing Technology Center of Japan

Ship Detection

User Requirements Expected Results and
SAR Capabilities
  • Detect ships >= 25m length in up to sea state 5.
  • Detecting vessels > 100 tonns in up to sea state 5.
  • Detection of illegal fishing by foreign vessels in Canadian waters.
  • Protection of fisheries against over-exploitation and illegal shipping.
  • Enhanced maritime domain awareness of Canada's coasts and their approaches.
  • Improved security and support to sovereighty.

RADARSAT-1's capability to detect ships has enebled it to become a valuable resource for maritime surveillance programs.
