Offshore Wind Farm Protection

Cambridge Pixel has supplied its RadarWatch coastal surveillance software, target tracking and radar recording solutions to Klein Marine Systems, a subsidiary of Mitcham Industries, Inc. as part of a project to protect an offshore wind farm and its associated submarine transmission line off the coast of South Korea.

The offshore platform hosting a Simrad Argus X-band radar, dual thermal/daylight camera, and an AIS receiver was supported by Cambridge Pixel's SPx tracking server, which generates radar tracks. These track reports, along with camera video and AIS reports, are transmitted to the shore-based facility where the RadarWatch surveillance application presents the combined radar, camera and AIS transponder data in a unified operator-friendly display.

Maritime Display Framework

Cambridge Pixel has developed a Maritime Display Framework (MDF) application, providing developers with an extended source code example which may be customised and enhanced to meet project-specific requirements.

The MDF is written in C# and is designed for development of a Windows WPF-based client application. The application demonstrates the use of Cambridge Pixel's core SPx libraries for radar video and track data display on a moving platform, providing a solid foundation for customisation.

The MDF application includes the following features:

  • Radar video and track receipt and display
  • Navigation data receipt
  • S57 chart display
  • True/relative motion display modes
  • North-up, heading-up and course-up display referencing
  • Secondary PPI displays
  • Camera video receipt and display

AVx VideoLink

AVx VideoLink is a new product to address the problems associated with sending video data over unreliable networks. AVx VideoLink makes the best use of the available bandwidth without imposing unnecessary overheads. It is particularly well-suited to transmission of video across radio links, making it ideal for unmanned surface vessel, oil platform or mobile surveillance projects.

AVx VideoLink uses a novel approach of separating the data transmission into two distinct parts: a server application and a relay application. The server receives the H.264 video directly from the camera and re-encodes it in a proprietary format for onward transmission across the wide area network. The relay is then responsible for receiving video packets at the far end, withstanding packet loss and reassembling them back into an H.264 stream for the consumer.

Sensor Processing for USVs

Cambridge Pixel's portfolio of products encompasses a broad range of specialised sensor processing capabilities, many of which are useful for unmanned surface vessel (USV) projects. For this reason we are involved in a number of USV projects with leading companies around the world.

Radars are often among the sensors installed aboard USVs, providing wide area coverage and long-range detection of potential obstacles. Cambridge Pixel's products have been used to interface to an extremely wide range of radars, from small commercial models up to specialised military ones. Our modular approach to radar processing means that system integrators can select products to provide specific functions, allowing them to build capability quickly.

More information about Cambridge Pixel's USV capabilities is available here.


During the current Coronavirus crisis, Cambridge Pixel is maintaining a near-normal business operation. We have fewer people in the office and our office hours are subject to some adjustment but we are continuing to supply and support our customers.
