Primagraphics Launches Osprey Radar Input Card in PMC Format

9/5/2002 - Primagraphics, the command & control, video and graphics specialist, has introduced its Osprey integrated radar capture card, the latest in the new Hawkeye family of commercial-off-the-shelf (COTS) sensor input and display cards in PCI Mezzanine Card (PMC) format.

The low power, ruggedised card will operate in a wide range of environments, including conditions of high temperature and vibration. It is designed for applications including networked radar video servers, naval command and control display consoles, radar head monitor systems and airborne radar display consoles.

Osprey provides an interface to a wide range of radar signal types in a compact, PMC form factor. The card can interface to a wide variety of radars including: ASDE-3, RADDS, SPS-40, KH-1007, and Terma Scanter. A wide range of PRF rates, rotation rates, and effective sampling rates can be accommodated without hardware change.

Osprey digitises up to three synchronous analogue radar videos at 50 MHz to 10-bit precision. This data can then be converted to 8-bit or 4-bit samples using a programmable function. Mixing between the three videos and up to 8-bits of digital radar data is also possible. In "raw" mode, up to 16k samples per return can be transferred to the host. Alternatively, range gating and sub-sampling can be performed.

The card also supports azimuth processing such as azimuth correlation. Radar start, stop and reverse can be detected automatically as an aid to sector-scan processing. Various azimuth formats such as ACP/ARP and serial azimuth are supported on the card. An add-on Synchro/Resolver module is also available.

An onboard PowerPC processor provides high-level control of the Osprey's functions and also allows the implementation of custom radar signal processing algorithms. The card includes special features to improve noise immunity and clutter suppression whilst ensuring that small targets are not missed. Every return is individually time-stamped.

The Hawkeye PMC family brings Primagraphics' many years of expertise in sensor input and graphic board design to the PMC format. Primagraphics is a recognised leader in the development of processing and display systems for military and civil applications. Its systems, for VME, PCI and PMC formats, are in use throughout the world for airborne and shipborne command and control consoles, vessel tracking, air traffic control and air defence systems.
