Navtech Selects Cambridge Pixel's RadarVision to Integrate Radar into VMS for Major Tunnel Project

  • RadarVision software modules for radar scan conversion and H.264 compression and distribution integrated with Navtech’s ClearWay™ Automatic Incident Detection (AID) traffic monitoring system.
  • ClearWay™ AID system with RadarVision technology is now being deployed in Norway for the world’s longest underwater tunnel to give operators improved situational awareness even when visibility is compromised by smoke and fire.
  • RadarVision converts radar data into a camera-like data stream for the presentation of high fidelity radar on any video management system (VMS).
  • Navtech Radar Limited has selected Cambridge Pixel’s RadarVision technology to enhance its ClearWay™ Automatic Incident Detection (AID) traffic monitoring system for deployment on a major new underwater tunnel project in Norway.

The RadarVision software modules for radar scan conversion, H.264 compression and distribution will allow high fidelity radar images to be viewed alongside data from traditional daylight and thermal cameras on a standard video management system (VMS).

Navtech’s ClearWay™ automatic incident detection system is now fully integrated with the RadarVision modules, and set for deployment in Norway's Rogfast tunnel, the world’s longest underwater tunnel, connecting the cities of Stavanger and Bergen.

The project involves over 100 Navtech high resolution 77Ghz traffic radars to help deliver operator improved situational awareness even when visibility inside the tunnel might be compromised because of smoke and fire.

Guy Avery, software development manager, Navtech Radar, said, “Providing tunnel operators and the emergency services with radar-based visual capability during a major incident has been on our development road map for some me. The key obstacle has been the ability to take complex radar data and display it in such a way that an operator can immediately see what is happening in the tunnel.

“We needed to deliver a solution that offered the same visual clarity as CCTV, but would work in all conditions, including in a tunnel potentially full of smoke and fire. Cambridge Pixel’s RadarVision technology not only allows us to provide this data as a standard video feed, but we have been able to merge in all the critical data the operator needs, including real-time positions of vehicles and people. All the real-time data can then be superimposed over a scaled schematic of the tunnel enabling us to give immediate context to any viewer.”

RadarVision interfaces to radars at the level of video, plots or tracks and creates a picture of the radar information, optionally with maps underlaying the radar. The picture is then converted to a camera-like IP data stream for input to any VMS. This means that any video management system could be easily interfaced to a radar and be used to display and manipulate the radar picture.

David Johnson, CEO, Cambridge Pixel, commented, “We are delighted that our recently launched RadarVision product has been selected by Navtech to enhance the ClearWay traffic monitoring solution for this prestigious underwater tunnel project. Our software will enable each radar to be treated as a virtual camera giving tunnel operators unprecedented situation awareness in all conditions, including during major incidents where normal camera technology would be severely hampered by smoke and fire.”

RadarVision can be interfaced to a wide range of security, maritime and specialist radars, accepting radar video as either radar signals through an acquisition card, as ASTERIX CAT-240 network data or in proprietary formats. This data is then scan converted into an image and then outputted as a H.264 (RTSP packaged) network video stream that feeds directly into a video management system. 

RadarVision is available as a software application or as a box level solution and provides a wide range of radar acquisition, processing and display options that allowa a radar to be added into existing security solution quickly and easily. No changes are required to the cameras or display system already in use; a suitable radar may simply be installed and connected to the Video Management System through RadarVision.

Cambridge Pixel’s radar technology is used in naval, air traffic control, vessel traffic, commercial shipping, security, surveillance and airborne radar applications. Its systems have been implemented in mission critical applications with companies such as BAE Systems, Frontier Electronic Systems, Barco Defence, Blighter Surveillance Systems, DRS, Exelis, Kelvin Hughes, Lockheed Martin, Navantia, Navtech Radar, Raytheon, Saab, Royal Thai Air Force, Samsung Thales, Sofresud and Tellumat.
