Mercury Computer Systems to Deliver OpenVPX-Based Signal Processing Solution for Global Radar System Upgrade

CHELMSFORD, Mass.  October 26, 2009  Mercury Computer Systems, Inc. (NASDAQ: MRCY, www.mc.com), a leading provider of embedded computing systems and software for image, sensor, and signal processing applications, announced it received a multimillion-dollar system order from a leading defense supplier for its global radar upgrade program.

Mercury will deliver a complete signal processing solution employing its OpenVPX™-compliant Ensemble™ 6000 Series products. In addition, Mercury’s Services and Systems Integration organization is providing comprehensive professional services aimed at the development, validation, and qualification of the complete subsystem for this ground-based defense system.

Mercury’s innovative multi-plane architecture simplified the system design while supporting scalability and facilitating interoperability between the different elements in the system. Leveraging the design principles of the OpenVPX System Specification, Mercury is able to deliver superior signal processing capability in a heterogeneous environment overlaid with a robust systems management infrastructure.

Mercury’s commitment to performance migration through software portability protected the Customer’s investment in radar processing software while providing significant performance enhancements – without the need to rearchitect the Customer’s application. Moreover, Mercury will support the Customer’s Quick Reaction Capability (QRC) by delivering an integrated OpenVPX-based architecture in less than 10 months, with low-rate initial production in just under 16 months.

“The Customer is focused on leveraging standards-based architectures while meeting their customers’ increasing demands for more warfighting capability, more rapidly, and at lower cost,” said Didier Thibaud, General Manager of Advanced Computing Solutions at Mercury. “Mercury’s standards-based road map and software portability, combined with our renowned expertise in the development, interoperability, and optimization of embedded signal processing systems, clearly position us as the partner of choice for this vital upgrade.”
