UK-based Cambridge Pixel is supplying SPx radar plot extraction and SPx scan conversion software to South African technology company Tellumat for the South African Air Force’s airfield approach radar systems.

Using the SPx library modules, Tellumat has implemented a dual-channel radar processing system that selects an area of interest from the incoming video and extracts plots of potential targets.

The system uses Cambridge Pixel’s HPx-100 radar interface card to interface to multiple videos, trigger and azimuth data of the air force’s ATCR-33 radar.

The digitised video is then processed by the SPx plot extraction and plot merging module.

In addition, the SPx scan converter module supports the plan position indicator (PPI) display of selected video inputs, which is then overlaid with graphics symbology.
