Air and Missile Defense Radar (AMDR)
The Highly Capable, Truly Scalable Radar
The Air and Missile Defense Radar is the Navy's next generation integrated air and missile defense radar. It is currently planned to be deployed on the DDG-51 Flight III beginning in 2016.
The radar significantly enhances the ships’ abilities to detect air and surface targets as well as the ever-proliferating ballistic missile threats.
Meet the Navy's Air and Missile Defense Radar
AMDR provides greater detection ranges and increased discrimination accuracy compared to the AN/SPY-1D(V) radar onboard today’s destroyers.
The system is built with individual ‘building blocks’ called Radar Modular Assemblies. Each RMA is a self-contained radar transmitter and receiver in a 2’x2’x2’ box. These RMAs stack together to fit the required array size of any ship, making AMDR the Navy’s first truly scalable radar.
This advanced radar comprises:
- S-band radar – a new, integrated air and missile defense radar
- X-band radar – a horizon-search radar based on existing technology
- The Radar Suite Controller (RSC) – a new component to manage radar resources and integrate with the ship’s combat management system
- Scalable to suit any size aperture or mission requirement
- Over 30 times more sensitive than AN/SPY-1D(V)
- Can simultaneously handle over 30 times the targets than AN/SPY-1D(V) to counter large and complex raids
- Adaptive digital beamforming and radar signal/data processing functionality is reprogrammable to adapt to new missions or emerging threats
Reliability and Affordability
AMDR’s performance and reliability are a direct result of more than 10 years of investment in core technologies, leveraging development, testing and production of high-powered Gallium Nitride (GaN) semiconductors, distributed receiver exciters, and adaptive digital beamforming. AMDR’s GaN components cost 34% less than Gallium Arsenide alternatives, deliver higher power density and efficiency, and have demonstrated meantime between failures at an impressive 100 million hours.
AMDR has a fully programmable, back-end radar controller built out of commercial off-the-shelf (COTS) x86 processors. This programmability allows the system to adapt to emerging threats. The commercial nature of the x86 processors simplifies obsolescence replacement – as opposed to costly technical refresh/upgrades and associated downtime – savings that lower radar sustainment costs over each ship’s service life.
AMDR has an extremely high predicted operational availability due to the reliable GaN transmit/receive modules, the low mean-time-to-repair rate, and a very low number of Line Replaceable Units. Designed for maintainability, standard LRU replacement in the RMA can be accomplished in under six minutes – requiring only two tools.
Scalable. Capable. Reliable. Affordable.
The Air and Missile Defense Radar is expected to meet the Navy’s current and future mission requirements – and will be ready to protect against the threats of today and tomorrow.
