New HPx-200 Radar Input Card
Expanded Radar Interfacing Options
Cambridge Pixel's new radar interface card, HPx-200, expands the options for interfacing to commercial and military primary hpx-200-smallradar systems. The new card is form-fit-function compatible with the established HPx-100 card and for most situations will be a direct replacement. The card is fully supported with Cambridge Pixel's SPx library, SPx Server and RadarView.
New capabilities of the HPx-200 include expanded interfacing capabilities allowing RS422, opto-coupled or software configurable signal thresholds to be set. An optional end-of-range signal is now supported, allowing video returns to be truncated on receipt of a signal. The card also features increased resolution to 12 bit sampling and the option to capture two 8-bit videos simultaneously.

Expanded Windows Support in SPx Development


The SPx Development software is now fully supported under Windows 7 operating system and we are still supporting XP and Vista. In addition, we are now (V1.39)


supporting Microsoft's Visual Studio 2010 dev


elopment platform for those developers wishing to upgrade from VS-2005 and VS-2008. 


As always, SPx Developers with an active license can upgrade free-of-charge to the latest SPx software release. Contact Cambridge Pixel for details.




RadarView Map Display Enhancements

RadarView Gets Map Display Feature Enhancements


RadarView, Cambridge Pixel's PC-based radar visualisation software, has been enhanced to subusan2pport a built-in vector map as an underlay to the radar video. This map database provides full world coverage with a 40m resolution and is available as standard with all versions of RadarView. Multiple layers of radar video may be scan converted and blended with the map.
We are in final stages of testing the latest set of RadarView display enhancements which will include AIS target display. This will allow RadarView to display primary radar video, primary plots, tracks and secondary-derived AIS or ADS-B overlays.

COTS Journal Article


In this month's COTS Journal (May 2011), Cambridge Pixel's David Johnson describes how a modern cots-journalopen-systems approach to radar display system provides significant cost savings for naval command and control displays.


By using general purpose hardware and a flexible open software structure that is open to change, systems integrators can develop advanced, flexible real-time radar displays while reducing lifetime costs.

Tech Notes - From Recent Technical Support Issues

Multicast network distribution
A radar or video distribution system using standard Ethernet networks offers a very cost-effective solution for distribution of sensor data. If data is sent using multicast distribution, many client displays can receive distributed data without a per-client network load. However, multicast distribution is not as easy as it first seems. Consideration and care must be given to the selection of a network switch that allows clients to request receipt of selected multicast groups.  The switch is then responsible for selective transmission of multicast packets to clients that have requested them. Each server will be sending its data to the switch and the switch only delivers the packets to those clients that have made an IGMP subscribe to the multicast address. With a properly configured switch and server/client software that properly respects the multicast protocols, the resulting network is extremely efficient, with clients only receiving data that they are interested in, yet with the ability to change their subscription in real-time.
