SPS-49 Agile PESA (SAP)

The U.S. Navy SPS-49 marshalling, surveillance and weapons queuing radar is essential to the Navy’s mission across the fleet. Performance and affordability of these radars is paramount. Performance encompasses the inherent ability to execute the mission: technical capability and system availability. Affordability encompasses all elements of life-cycle cost – Total Ownership Cost (TOC): development, acquisition, operation and long-term sustainment expenses. The system has been deployed 30+ years and requires significant improvements in reliability, operational readiness, TOC and capabilities. The Navy requires a complete above deck technology refresh to mitigate component and system obsolescence, reduce maintenance and energy consumption, reduce weight and cost, and increase performance with an aggressive deployment schedule.  Colorado Engineering, Inc. (CEI) formed a team of experts and is leading the effort to design, develop and produce an upgraded SPS-49 antenna addressing these requirements.  The team has designed and modeled two antenna architectures within the trade-space of performance, weight, cost and polarization.
