SeaDarQ - Radar Oil Spill Detection System
From Sensors and Systems
The SeaDarQ radar based oil spill detection (OSD) system features; Proven solution with long range, high accuracy and low false alarm rate. Adapted for installation both onshore and offshore.
How does it work?
OSD Radar Processors monitor the presence of capillary waves, caused by the wind effecting the water surface. It does this by detecting the radar backscatter caused by the uneven water surface. This back scatter is filtered out on a normal navigation radar to give a clear image of large, hard edged targets.
Oil floating on the water surface will however supress the capillary waves, that in turn will remove the backscatter. When an OSD Radar processor detects an area with no capillary waves, it could be a possible oil spill. Such events are automatically detected, and the operator is alerted. The OSD Radar processor will then mark and measure the area of the suspected slick and calculate the speed and direction of the drifting oil slick.
To be operational, the radar needs wind between 2 ...
To be operational, the radar needs wind between 2 and 12 m/s. Also note that x-band radar systems CANNOT measure relative or accurate thickness of an oil slick. To measure relative thickness, the most cost efficient method is using infrared camera systems, cooled or uncooled.
