Vessel traffic and port security management is being made easier with new software that enables the display of sophisticated radar imagery with maps and target symbology on hardware.

Cambridge Pixel, a developer of radar display, tracking and recording sub-systems, has introduced new software components to enable the display of radar video on any computer, tablet or smart phone running a standard Internet web browser such as Edge, Firefox, Safari or Chrome.

Andrew Haylett, product manager at Cambridge Pixel, said: “The browser-based approach separates the processing from the display and therefore any device capable of running a browser can serve as the display. This can simplify the deployment of a new installation and reduce cost as the only software necessary at the display end is the browser itself.”

Integrated surveillance

This Radar Video in a Browser application simplifies the construction of web-based display applications for maritime, naval, air traffic and security system integrators. The new software components enable radar video to be displayed with maps, tracks (primary radar tracks, fused tracks, AIS, ADS-B) and alarms as part of an integrated surveillance picture. Radar processing can be handled by a remote server or delivered via a cloud-based architecture for rapid scalability, with licenses to support up to 100 clients.

As part of the new product, a scan conversion server application, SPx Radar Web Server, receives radar video and creates radar images. The browser connects to the server and requests radar video for the geographic area that it is displaying. The radar image for that area is created and delivered to the browser where it is blended with underlay and overlay graphics, including maps and target symbology.

The Radar Web Server also assists with track display. The Server receives tracks from a target tracker and selectively delivers those tracks in a GeoJSON format to connected clients. The client’s geographic areas of interest serve as a filter to control the delivery of track reports. The JSON track messages are then rendered in the browser using JavaScript.
