Offshore infrastructure such as oil and gas processing platforms and FPSOs have the same needs for management of vessel traffic around the asset and neighbouring assets. Often the offshore facility is completely self-reliant and requires appropriately located radars to provide VTS, safety, security and private surveillance of the surrounding sea area.
The SBS (Shore Based Sensor) radar range meets the requirements of IALA recommendation V-128 and we work with system integrators to enable the correct solution to be specified according to the end user's requirements.
SharpEye™ offshore radar systems provide the user with the ability to detect cooperative and uncooperative targets at longer ranges, earlier and in heavy rain and high sea states.
With hundreds of commissioned SBS systems worldwide operating reliably every day in ports, along coastlines and on offshore oil and gas platforms and FPSOs, SharpEye™ is proven in any coastal and offshore surveillance environment.

SBS systems are fully remote controlled providing 24/7 operation and achieve extremely high range accuracy and target discrimination in range and azimuth. A significant differentiator between a SBS solid state radar solution and the next nearest alternative is full weather adaptability. A SharpEye™ solution adapts automatically to changes in the weather and environmental conditions without the need for any operator intervention.
Another significant differentiator is the interoperability, SharpEye™ systems do not interfere with other systems and are not susceptible to interference from other radar transmissions.
SharpEye™ Solid State Pulse Doppler Radar
SharpEye™ radar technology meets the detection challenges of offshore infrastructure operators through a clever combination of radar techniques designed to provide the best performance in all conditions, whilst also providing the flexibility to be optimised for specific detection needs.
Solid state radar ensures extremely high reliability and low through life costs:
- No magnetron - minimal routine maintenance requirements
- High MTBF - high availability and reliability
- Upmast and mast mounted transceivers - reduced waveguide - reduced signal loss - reduced infrastructure and operational costs
- Frequency diversity
- User selectable frequencies to ensure interoperability
SharpEye™ transmits a low power patented pulse sequnce, which enables short, medium and long range radar returns to be detected simultaneously, allowing the radar operator to maintain situational awareness regardless of the range scale setting of the radar display and other users of the radar can select their own radar display range scale.
Doppler processing of radar returns provides coherent information concerning target velocity (radial) and enable the detection of very small and slow moving objects and targets with a low Radar Cross Section (RCS) and through a series of electronic filters is able to distinguish between the targets of interest and sea, rain and land clutter.
SharpEye™ X-Band transmitters are the first in their class to employ Gallium Nitride (GaN) power transistor technology. The significant performance benefits of GaN transistors have been harnessed to directly improve the performance of the radar.
Other differentiating technologies include Moving Target Detection (MTD) providing enhanced clutter suppression at the Doppler processing stage and pulse compression of the return signal enabling a low transmit power providing efficient use of the radar. Other Doppler radars may employ less advanced techniques such as Moving Target Indication (MTI), which does not take full advantage of the radial velocity information.
Upmast and Mast Mounted Transceivers
The SBS-800 range is configured to provide an upmast ultra-high reliability system without the need for dual redundancy of the radar sensor itself.
The SBS-900 range is configured to provide a mast mounted environmentally sealed enclosure. With minimal waveguide, signal loss and infrastructure costs are reduced, whilst providing a mast mounted system that meets the 'Advanced' availability requirement or can be configured to provide an 'X and S' Band system.
Standard types include patented low profile designs to reduce wind loading, horizontally polarised slotted waveguide open array antennas.
Advanced antenna designs available as horizontal or circular polarised.
Sizes range from 3.7m to 6.4m.
Careful selection of a surveillance radar system is required to ensure the target types can be detected and tracked in the designated area. Visibility, precipitation rates, sea states and propagation conditions relevant for the individual radar site also require careful consideration by the radar supplier to enable the optimal system to be specified.
Our approach to radar system design is to work closely with the right system integration companies to provide the end user a solution that is expertly recommended according to the specification and the actual application environment.
