THE ADVANCED MULTIFUNCTION RF
CONCEPT (AMRFC)
ONR initiated AMRF-C to determine the
possibility of using wide-band arrays to
meet multiple RF functions simultaneously
ONR used an open architecture
approach to RF systems to allow multiple
vendors to participate and pave the way for
scalable, upgradable systems
The Multi Function Electronic Warfare
Future Naval Capability (MFEW FNC)
resulted from this effort
Demonstrated Functions
 Comm: X-Band DSCS Satcom Link, Ku-Band
Commercial Satcom Link, Ku TCDL
 Navigation Radar
 Electronic Warfare: Electronic Surveillance,
Electronic Attack
 Calibration

MFEW DEVELOPMENT GOALS
 Meets key Electronic
Surveillance capabilities: High
Probability of Intercept
(HPIO), Precision Direction
Finding (PDF) and Specific
Emitter Identification (SEI)
 Capable of supporting
additional RF functions
 Supports other platform
configurations, including
back-fit
 Technology transitions to
fleet
 Architecture that is modular,
scalable and open

OPEN ARCHITECTURE SUCCESS
 Separate contract let to DRS to develop a RFC SRU that met the
open interfaces of the Northrop Grumman (NG) MFEW ADM
architecture
 DRS developed the SI-9161 RFC in parallel with their SI-9155
enabling ONR to leverage DRS investment in the SI-9155 for the
NGC compatible SI-9161
 The lessons learned on one configuration was leveraged to both
– the Si-9161 development efforts, collaboration with ONR and NG
was very valuable to the success of the SI-9155
– The modular and forward thinking design of the two receivers
enables the features between the SI-9161 and SI-9155 to
effectively be interchangeable
 The DRS RFC was used by Lockheed Martin (LM) during their
RIMPAC testing
– LM was able to integrate the SI-9161 in their ES architecture within
a week
– LM proposed the SI-9161 as part of SEWIP Block 2
– LM is also using the SI-9161 SEWIP Block 1B HGHS

INDUSTRY SUPPORT
 Ensure broad industry involvement in open architecture
and standards development
– Visits to and from industry
– NDIA workshops (Industry and Navy participation)
 Approximately 20 companies/40-50 individuals
 8 November 2006 – Overview and feedback on IT INP
 2 May 2007 - Business case
 28 June 2007 – Requirements and architecture
 2 August 2007 - Organization to define standards
– Integrated Topside INP RFI responses received
 Initiated industry co-led modular open RF architecture
definition process in FY08

Order of the four blocks (from
isolation control to combiner
network) could vary depending on
the architecture. Filters may be
placed after amplifiers, amplifiers
after the phase shifters, even some
level of combining may occur
before phase/amplitude control.

CHALLENGES, RISKS AND
IMPLICATIONS
•
•
•
•
•
•
•
Confirmation that SRU/CSCI interfaces and specifications are
accurate and sufficient for acquisition from alternate sources
Navy must provide protection of contractor intellectual property
even as it demands compliance with MOSA
The price for lower total life cycle cost could mean higher initial
acquisition cost
Standards selection can be risky and problematic requiring greater
knowledge on part of the government
Interface standards evolve with time. Difficult to project the extent
a given standard will endure or should be replaced
Standards-based architectures tend to change the focus of systems
engineering from design to integration
Shorter commercial product lifetimes create logistical support
challenges
17
POTENTIAL OPERATIONAL PERFORMANCE
BENEFITS OF OA BASED TOPSIDE SYSTEMS
•
The ability to adapt to evolving requirements and threats
•
Accelerating the transition from S&T into acquisition and
deployment (make technology refresh an asset, not a liability)
•
Ensuring that the system will interoperate with all the systems
with which it must interface without major modification of
exiting components
•
Improving the extensibility for meeting new requirements and
for introducing new capabilities

DIGITAL ARRAY RADAR
PREMISE/GOALS
 ONR’s government owned and integrated Open Architecture Digital Array
Radar sunsets in FY12
 Open Architecture test bed enables investigation of alternative solutions
and risk reduction
 Core government team with competency to design, build, and test next
generation multi-mission radars (similar to SPQ-9, SPS-49, and APS-137
programs of the past)
 Improves government ability to trade requirements throughout the
development cycle
 Competition at the subsystem level (vice TSPR) widens the pool of
vendors able to compete
 Constrain contractor costs by evaporation of sole source
 Government develops and owns requirements and specifications
 Government competitively selects subsystem vendors
 The government has no business model impediments to the extensive
adoption of relevant open commercial standards and specifications

CONCLUSIONS
 ONR has a solid S&T foundation to support MOSA based
systems of the future
 OA is a real enabler for making systems more affordable
– Leverage commercial investment;
– Enhance access to cutting edge technologies
– Enhance commonality and reuse across platforms
– Enable increased competition
 Industry is a willing partner and its involvement is essential
in defining MOSA based architectures and standards
“Specifying modular architecture and open software standards is
essential to allow spiral development of optimal systems design constant evolution in capabilities should be expected.”
