Sperry Marine unveils high-resolution radar

Sperry Marine has unveiled SeaGuard, a high-resolution radar system to improve navigational awareness for operators of very large cruise ships.  

{mprestriction ids="1,2"}SeaGuard was originally designed as a naval surveillance radar capable of identifying small targets in water. The radar differs from conventional radar by providing very high resolution in a solid state transceiver, which can scan for targets almost simultaneously across six different frequencies.

Substituting the conventional magnetron receiver delivers improved ‘clutter’ correction and much better performance, especially in bad weather. SeaGuard can support navigators when manoeuvring in congested ports and harbours and can also assist with search and rescue in the event of a casualty involving passengers or crew.

Pascal Göllnitz, associate product manager, Northrop Grumman Sperry Marine, said: “As cruise ships continue to grow in size and passenger numbers increase, so do the navigational risks they encounter and operators are more concerned with minimising the risks of collision”.

“It’s also a regrettable fact that cruise ships can be involved in searching for people lost overboard. It is no exaggeration to say that being able to quickly identify and retrieve people from the water can be a life saver.”

SeaGuard is intended as an auxiliary system for use in specific operational conditions, providing an additional layer of situational awareness. The solution benefits from an intuitive interface with the display and menu structure very similar to its navigation radar and ECDIS platforms.

“SeaGuard is specifically designed to focus on and distinguish small targets in the water than the navigator would not normally see,” said Göllnitz.

“Because the system generates high resolution clusters in smaller cells, SeaGuard also provides more accurate video response and a more detailed picture, depending on the targets prioritised by the user.”

SeaGuard can be installed via a single connection between transceiver and display, and configuration via a dedicated screen or an auxiliary unit.{/mprestriction}
