Simrad Radar and VHF Chosen for Coast Guard Patrol Boats

Simrad has been selected to supply radar and VHF communications equipment to 100 patrol boats currently in production for the Yemen Coast Guard. Delivery and installation of the CR44 radar and RD68 dVHF radios for the first 25 boats is underway. Installation will continue throughout the year with the final patrol boat completed by the end of 2004. The CR44 multi-function radar from Simrad’s xx44/54 series of professional GPS ChartRadars, Chartplotters, ChartSounders and ChartRadarSounders has been chosen as the main navigation tool onboard. Including an easy to operate control panel with quick response keys for each function, the CR44 has... (read more)

Planet Ocean Distributes Radac Radar Wave & Tide Sensor

Planet Ocean (UK) has signed an exclusive representation agreement with Radac (The Netherlands). The agreement covers the UK and Republic of Ireland. Radac has been developing the WaveGuide system since 1996. This high-quality radar-based system monitors waves, tides and water levels. The WaveGuide is compact, reliable and robust. Where a fixed structure such as a platform, turbine or jetty already exists, it offers a simpler-to-install, largely maintenance-free alternative to buoy-based systems. The WaveGuide is a standalone system, which requires no calibration. It incorporates a web interface which allows direct access to the wave data. Unique to Radac is the WaveGuide... (read more)

Collaboration with Helzel for Improved HF Radar Systems

Northern Radar and ASL Environmental Sciences, Canada, and Helzel Messtechnik, Germany, have entered into a Memorandum of Understanding (MOU). The three companies have come together to collaborate on the marketing, sales, design, manufacturing, installation, maintenance and operation of oceanographic high-frequency radar systems for non-military applications. This collaboration has led to the development of the 'WERA NorthernRadar' system – an updated and enhanced version of the 'Helzel WERA' HF radar system. The WERA NorthernRadar is an oceanographic HF radar providing simultaneous measurement of surface currents maps, ocean waves parameters and maps and wind direction (wind speed under development). These measured data... (read more)

Norbit Aptomar Acquires SeaDarQ Radar System for Environmental Monitoring

Nortek has announced the sale of its SeaDarQ radar technology for environmental monitoring and oil spill detection to Norbit Aptomar, a technology provider to global maritime markets. Norbit, which is headquartered in Trondheim, Norway, will integrate the SeaDarQ software with its existing SeaCOP environmental monitoring system. The SeaCOP system combines remote sensing technologies – such as radar, infrared cameras and sonars – with state-of-the-art data fusion and artificial intelligence. Using a high-resolution marine X-band radar, the Norbit Aptomar SeaDarQ system can automatically detect, track and monitor oil spills on the ocean surface. Detection and Tracking Algorithms Nortek’s subsidiary in the Netherlands... (read more)

Northrop Grumman to Supply Navigation Radar Sets for U.S. Navy Submarines

Northrop Grumman Corporation has been awarded a contract by the Naval Sea Systems Command to supply navigation radar sets and associated systems engineering for 10 U.S. Navy submarines. The company's Sperry Marine business unit will deliver AN/BPS-16 (V) 4 navigation radar sets for six Virginia-class attack submarines and four guided-missile submarines. Deliveries will begin in late 2005 and continue through 2010 if all options are exercised. The contract includes development of automatic radar-plotting aid software for the Virginia-class submarines and an upgrade of the Voyage Management System, which provides integrated navigation capability and complies with the Chief of Naval Operations'...

Wave Radars

A comparison of concepts and techniques

Radar Remote Sensing of ocean surface waves may in general be defined as measuring characteristics of the sea surface by means of electromagnetic waves so that the sea surface is itself not disturbed. The electro-magnetic waves transmitted by the radar antenna are scattered back from the sea surface, modulated in amplitude and phase or frequency by the interaction with the sea surface in motion. This modulation carries information about sea-surface characteristics, surface waves and currents. Oceanographic data is extracted from the backscatter signal by sophisticated signal processing and data analysis. Why remote sensing? Surface ocean waves may be measured by... (read more)

Proliferation SeaSonde Coastal Current-Mapping Radars

HF interference to improve coverage performance

For several decades while coastal HF current-mapping radars were under development, they radiated rarely and only for a few weeks at a time. Now 120 commercial SeaSonde units have been sold and seventy operate continuously in permanent locations. Their numbers are presently increasing at a rate of about 35 per year and they are used for a variety of maritime purposes. Although emitting only 50 watts of power they can map currents to 200km on the lower frequencies; these signals may also travel half way around the world, thanks to overhead reflecting ionospheric layers. After all, these same layers have... (read more)
