Superior radar for Seismic operations.
Sea-Hawk has delivered Radar systems to the majority of Seismic companies.
Feedback from operators shows that the Sea-Hawk find debrief in the surface which can be harmful to the seismic cables.
In the scenario above, the Sea-Hawk radar detected these most dangerous bits of ice at much longer distance and in greater detail than any other radar. Sea-Hawk supplied you with an early warning and a more detailed view.
The Growlers only show a little portion above the surface, and they are therefore very difficult to detect and by that also very dangerous. One Growler could destroy the very valuable streamers, and is a potential threat as such.
If you are looking for very detailed surface detection for your vessel or for your offshore location, a polarimetric radar antenna should be the solution for you.
That is what Sea-Hawk radars are exclusively equipped with.
Like an aerial photo
Sea-Hawk can detect the surface within the radar horizon, displaying it similarly
to an unusually detailed aerial photo. We bring radar detection to a level you could only dream about until recently. The constant darkness in the Arctic call for superior systems to help you operate up here. A polarimetric radar could provide you with most valuable details for a safe passage.
There are many different bits of ice. The echo from ice bergs, bergy bits and growlers are highly complex for any radar to detect. This is where polarization is very important. Bergy bits can measure two square meters on the surface and much more vertically. A polarimetric antenna has a much higher probability-of-detection rate than a standard navigational radar.
Detection of growlers
Obviously, the ice reflects the radar signal differently, depending on size and shape of the ice above water. If we add windy weather to the scenario, with sea-state 4 or higher, surface detection becomes even more important. Growlers can be extremely dangerous and difficult to detect. However, they generate fluctuations in the surface and thereby background clutter, which is significantly greater than the return signal from a bergy bit. In reality, you can detect the growlers much more reliably with a polarimetric radar than with a conventional navigation radar.
Multi polarized
It has been verified that a polarimetric Sea-Hawk radar is able to detect ice in the surface at a much longer distance than a standard navigation radar. The reason for our polarimetric radar’s superior detection ability is the combined utilization of different polarizations (horizontal, vertical and circular), while standard navigation radars only utilize horizontal polarization. Furthermore, we are able to process the background clutter from the antenna, and the turbulence and fluctuations naturally produced by the sea. A two square meter growler in the sea is big enough to be significantly visible on a Sea-Hawk radar display.
