TRANSCRIPT
Innovating at the speed of light
OverviewThe AN/SPN-43D Radar Processor Upgrade is part of a comprehensive service life extension program (SLEP) to modernize and improve the ATC radars for the U.S. Navy’s CVN, LHD, and LHA class ships. C Speed’s Receiver and Radar Processor components, based on our flexible LightWave Radar technology, provide a highly cost-effective, modern, and easily installed & maintained solution to replace the aging SPN-43C receiver/processor equipment.
The Radar Processor Upgrade is comprised of two key components, the Transceiver and the Radar Data Processor, each provided in a dual-redundant solution and packaged in three replacement drawers. These comprise a core part of the complete AN/SPN-43D upgrade kit, which leverages much of the existing equipment for a low-cost, low-impact solution.
AN/SPN-43D Radar Processor Upgrade
Features• High-end digital signal & radar
processing capabilities
• Modern, reliable OTS-based components
• Incorporates steep radar channel filters to minimize interference from adjacent channel and out of band emitters
• Online built in test (BIT) and fault isolation
• Advanced, reprogrammable software-driven radar processing
• Staggered PRFs designed for rejection of targets from anomalous propagation
• Fully ruggedized for harsh, ship-board environment
• High value return on existing investment
• Standard ASTERIX (CAT 034/048/240) outputs
