SharpEye™ Solid-State Radar
SharpEye™ Solid-State Radar
SharpEye™ Technology - no magnetron
SharpEye™ is a radical and innovative departure from current marine navigation radar practice in that it is a mono-static pulse radar which uses the doppler effect to determine target velocities. This is achieved by processing received echoes in a bank of narrowband coherently integrating filters which resolve targets within particular velocity bands. SharpEye™ is able to separate targets from clutter due to their differing radial velocity components. This extra dimension gives a significant performance advantage in detecting small targets in clutter resulting in safer ship operations.
In addition to measuring the amplitude of the received signal, as in conventional radar, SharpEye™ extracts the relative motion of targets by measuring the phase of received radar echoes relative to the phase of the transmission. Extracting this information requires that the transmitter and receiver elements of the radar must be extremely stable, this precludes the use of a magnetron as the transmitting device.
To achieve this stability SharpEye™ uses a solid-state power amplifier with a peak output power of just 170W and a duty of 10%. This contrasts with conventional magnetron based marine navigation radar systems which have a 30kW output and duty typically less than 0.05%.
SharpEye™ transmits relatively long pulses in order to illuminate targets with sufficient energy for detection. To provide the required short range performance, SharpEye™ transmits a patented sequence of pulses of differing length, with each pulse optimised to cover a specified but overlapping range bracket.
A filter bank processes the echoes received from the pulse sequence to extract the radial velocities of targets and clutter alike. Within the digital signal processor detection thresholds for each of the filters within the bank are calculated adaptively according to sophisticated algorithms, providing optimum control of false alarms while maximising clutter suppression and target detection.
The technology also provides a Built In Test capability (BIT) wherein the system continuously measures key performance parameters such as RF output power, VSWR, oscillator frequencies and receiver sensitivity at frame rate and confirms to the user that the radar is operating within its performance envelope. This system provides an alert within seconds of any degradation in radar performance occurring and removes the need for operator initiated performance checks.
SharpEye™ technology and innovation provides the commercial marine market with a significant advance in both the performance and reliability of navigation radar leading to increased safety in ship operations.

MantaDigital™ is a radical and innovative departure from current marine navigation radar practice in that it is a solid-stage pulse radar which uses the Doppler effect to determine target velocities. Being solid-state means that there is no magnetron requiring routine replacement, this combined with its advanced technology makes it superior performance and lower through-life costs than a conventional magnetron based radar.
Designed for ease of operation MantaDigital™ ECDIS is the latest product from Kelvin Hughes' Manta development programme. Intuitive operation and a clear display of relevant information provides the operator with a decision making tool which enhances safety and efficiency. Simplicity and ease of operation is at the heart of Kelvin Hughes' design philosophy.
Multi-Function by Design
From the outset, MantaDigital™ ECDIS has been designed for true multi-functionality, providing a platform for Radar, Chart Radar, ECDIS and Conning Display options. MantaDigital™ is driven by Kelvin Hughes' "common-core" processor system which is now in use throughout the Radar, ECDIS and VDR product ranges providing enhanced functionality, reliability and low cost of ownership.
Simplicity of Operation
The user interface has been designed to be intuitive to operate and provide all the tools that the navigator needs for efficient and safe navigation without the need to explore multiple levels on each menu.
MantaDigital™ ECDIS is available in a variety of mounting configurations to meet the needs of different vessel types and operational scenarios. It can be supplied in options ranging from a single 20" desktop retrofit system through to a fully integrated navigation system. Display options include 20" and 26" high-definition screens for pedestal, desktop and mounting into consoles.
Employing the latest state-of-the-art technology the MantaDigital™ ECDIS offers a vast array of advantages to the navigator, from immediate situation awareness, through to sophisticated alarm management. The MantaDigital™ ECDIS uses the same three button and tracker-ball interface concept that has been used successfully in Kelvin Hughes' products for over 10 years.
The wide-screen MantaDigital™ ECDIS forms the core of ECDISplus. This is available as a desktop, pedestal or console mounted system with screen sizes of 20” or 26”. The main user interface is the tracker ball and three buttons which may optionally be mounted remotely. A standard QWERTY keyboard is also provided.
Chart data is the key component of any ECDIS system. To be an official ECDIS this has to be vector based ENC issued by a national Hydrographic authority. ECDISplus can be supplied with any official ENC chart data such as AVCS or PRIMAR. In addition, in ECS mode non-official or raster chart data can be displayed. The choice of suppliers will depend very much on the operating area of the vessel, Kelvin Hughes can make this choice for you to give you the most cost effective and safe coverage.
Managing electronic charts differs significantly from paper charts. Chart cells are loaded onto the ECDIS and activated using licences. Licences from different Hydrographic offices may have differing validity durations, so ensuring that the appropriate charts remain available is an important task. Ships whose trading patterns change will need new cells to be activated. Licences are available for three, six or twelve month durations. Kelvin Hughes can remotely manage the licensing process as part of the Outfit Management Service.
Managing changes to the chart database is key to keeping the chart outfit up-to-date and safe and meeting the Port State Authority requirements. ChartCo provides an update via broadcast, email or Internet technology. This service provides updates for paper and electronic charts and publications and includes additional services such as weather forecasting and routing and a news service. Updates can be passed directly to the ECDIS through the network or via CD. In addition Kelvin Hughes’ Outfit Management service can manage paper publications and charts alongside your digital data ensuring that at all times you are up-to-date, safe and meet the port state authority requirements.
ECDIS Backup and Flag Approvals
The requirements for ECDIS backup differ significantly across Flag States. As part of ECDISplus Kelvin Hughes will advise on the requirements relating to individual vessels and will provide and manage any “get-you-home” paper charts that may be required. Whatever the backup requirements Kelvin Hughes will deliver and manage a least cost solution ensuring that at all times the vessel’s data is up to date.
Whether for a new-build integrated bridge or a retrofit stand-alone, Kelvin Hughes is able to offer a complete installation and commissioning service world-wide.
As part of ECDISplus several standard packages are available, these can cover anything from commissioning only through to a complete install with cable laying, physical mounting of the hardware, commissioning and disposal of any redundant equipment. These installation packages are available at global locations and at fixed pre-agreed prices.
Kelvin Hughes provides a Flag State approved course based on the IMO 1.27 model. This course teaches the navigator to get the most out of their equipment and particularly familiarises the user with using traditional navigational methods on the ECDIS. The overall objective is to enhance navigational safety through safe operation and a thorough understand of the MantaDigital™ ECDIS.
Key areas addressed by the course are:
Electronic chart data and its display in an ECDIS

The Simplified Voyage Data Recorder or S-VDR is a system that the International Maritime Organisation (IMO) has mandated for carriage on the majority of large sea going vessels. It is a system similar to the aviation "black box" recorder where if a vessel is involved in an accident or sinks, data can be retrieved to reconstruct the last 12 hours of the vessels voyage. This allows the marine community to clearly understand the reason for the accident, however catastrophic and put in preventative measures to increase future marine safety.
The new rules stipulate that existing cargo ships on international voyages shall be fitted with an S-VDR as follows:
20,000 gross tonnage and upwards constructed before 1 July 2002, at the first scheduled dry-docking after 1 July 2006 but not later than 1 July 2009
3,000 gross tonnage and upwards but less than 20,000 gross tonnage constructed before 1 July 2002, at the first scheduled dry-docking after 1 July 2007 but not later than 1 July 2010
Administrations may exempt cargo ships from the application of the requirements when such ships will be taken permanently out of service within two years after the implementation date specified above.
The S-VDR collects data from the sensors on board the vessel, it digitises, compresses and stores this information in an externally mounted Crash Survivable Module (CSM) or float-free module. The data storage is a tamper-proof unit designed to be easily recovered in the event of a maritime incident, enabling the data to be replayed for investigative purposes.
