Polarimetric Radar System
All-in-One Polarimetric Radar for Advanced Surface Detection
VJ Engineering is the authorized agent of Sea-Hawk, Norway for Malaysia, Singapore and Brunei.
The Sea-Hawk Polarimetric Technology Performs When Commercial Radars Don’t. The Sea-Hawk technology represents the high end of radar sensor performance. This ultrasound-like radar image testifies to a dynamic that is never associated with standard radar screens. There are atleast two clear predictions for achieving such dynamic.
Our Sea-Hawk radar is designed for use within Seismic Operations, Piracy Detection, Vessel Traffic Services (VTS), Oil Spill Detection, Rescue and Surveillance, Offshore, Offshore Vessels, Ice going Vessels, High-Speed Craft (HSC), Merchant Shipping, Fishing & Coast Guard, and for users looking for advanced surface radars.
All in One Polarimetric Radar:
- Small target detection
- Oil Spill detection
- Rescue operations – Pirates – Ice detection
- X Band ARPA Navigation Radar
Sea-Hawk Radar Detection System Features:
SMALL TARGET DETECTION: Ice, Surface, and Small Target Detection – Sea-Hawk’s Polarimetric Radar are used by Seismic and Seismic Support vessels for advanced surface detection during seismic survey operations. Sea-Hawk can detect very small objects which can be harmful for the seismic cables.
OIL SPILL DETECTION: The Sea-Hawk Radar can operate both in “Small Target Detection” and in “Oil Spill Detection”. For Oil Spill Detection the combination of Radar Antennas is optimised to get better ranging of Oil spill detection. The Sea-Hawk Radar can predict the volume of the oil slick by entering the estimated thickness of the oil-film.
ANTI PIRACY RADAR: Sea-Hawk polarimetric radars are multi-polarized, resulting in far more detailed detection ability than traditional radar systems. Sea-Hawk can detect very small, fast moving objects and would, therefore, increase your anti-piracy capabilities to a level you could only dream about until recently.
SUPERIOR SURFACE DETECTION & MULTI POLARIZED: Sea-Hawk can detect the surface within the radar horizon, displaying it similarly to an unusually detailed aerial photo. 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.
DIFFERENT TARGETS: These small and fast targets are obviously very different. It could be a skiff with a powerful outboard motor or perhaps a rapid RIB. In what shape the pirates materialize doesn’t matter. They appear on the screen.Polarization is the key. The size, shape, and distance of the moving targets, of course, reflect the radar signals differently. However, they all generate a wake, which you will easily detect with a Sea Hawk radar before the target is detected itself.
WEATHER CONDITIONS: Anti-piracy detection is important also in windy conditions. In sea-state 4 or higher, small targets become even more difficult to detect for a standard marine radar. Unlike normal X-band radars, Sea-Hawk still provides detailed and reliable data during wind, storm, and rain. It has been verified that a polarimetric Sea-Hawk radar is able to detect anything on 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 small target of two square meters is big enough to be visible in the sea.In calm weather, a vertical polarized antenna is superior for surface detection. The surface echoes are significantly stronger in the vertical plane than in the horizontal plane utilized in ordinary X-band radars. A “combo” polarimetric radar is therefore favorable for your anti-piracy system in all weather conditions, from calm to storm.
