CW Advantage Xi Radar Scan Converter

Radar Scan Converter

The Advantage Xi radar scan converter is a single slot, half length PCI card that accepts digitised radar data via PCI bus and scan-converts it for display. The scan converted radar picture is combined with graphics from the DVI-D output of a standard graphics card. The radar data may be derived from the Virgo PCI or Osiris PCI/PMC radar input card or from a distributed network data stream.

Scan conversion is performed mainly in software running on an embedded PowerPC® processor, with dedicated hardware assistance for range spreading and fading. The coordinate transform uses a field-proven algorithm which combines the best features of both forward and reverse scan conversion. There are no holes or spokes in the displayed image, even when zooming in at long range. All single-point targets are displayed.
