Overview
A display solution that uses a standard web browser will automatically support a wide range of display devices from smart phones through to desktop workstations, with no special requirements beyond the support for the browser. This is the perfect solution when information needs to be shared with the widest range of users. For radar display, tablet devices using wi-fi or 4G/5G data links are an attractive option for displays that need to be portable.
Cambridge Pixel's SPx Radar Web Server is a radar processing server that converts radar video into sequences of scan-converted images, which it can then serve to web browsers for display with maps, tracks and related symbology. A typical system architecture will have SPx Server at a radar site to receive and pre-process the radar video, then use SPx Radar Web Server to scan-convert and serve images to any number of connected browsers.
Each browser has its own unique view of the radar image, effectively having its own dedicated scan converter running in SPx Radar Web Server, allowing an operator to change scale and position independently of other users and to see the radar video at full resolution. In a cloud-based solution, a lightweight radar server (or HPx-346 unit) will receive the radar video and distribute it to a cloud-based server running SPx Radar Web Server. The client browsers then simply make HTTP requests for specific areas of radar data.
SPx Radar Web Server also handles track data (primary radar tracks, fused tracks, AIS, ADS-B), providing these in an extended GeoJSON format to connected browsers for rendering.
