Area Defense SR Space Based Systems EXPO RTD/SBR NTRAM DII GBFR DII 2006+ 2004 2003 2001 2000 1998 • Significant experience with transportable ground based radar systems • Leveraging strong technology and low cost production with economy-of-scale benefits 5 Trends in Modern AESA Architecture and Operational Effect
Logistics Packaging: Thin, Lightweight, Conformal – Reliability & Maintainability Focus Antennas. Fewer parts, LRUs, LRMs – Commonality among Systems – Depot/Logistics tail: worldwide Bandwidth: Ever-increasing full and – Same training manuals instantaneous bandwidth – Quick & Easy LRM Access
More Mission Functions: Radar, Comms, Electronic Warfare, ISR, Passive Sensing
Dynamic S/W Modes: Adaptive modes measure the electromagnetic and target environment
Performance – Multi-function/Multi-mission MOSA: Modular Open System Architectures allow for “best-of-breed” – Adaptable mission requirements – Hardware & Software Built-in Growth Cross-Domain Ops: Modes, – Scalable Performance at all levels Communications, & Processing – Net Ready, Net Centric, Compatibility in System-of-Systems Interoperable

7 Industry trends track commercial market for affordability
Module/Tile Costs Are Falling Dramatically…
$15,000 Prototype (2000) $14,442
$10,000 DEM/VALUnclassified (2000) LABOR $9,740 MMICs OTHER MATL F22/JSF T/R High volume price reductions Module Cost $5,000 History LRIP (134,000) $750 HRP (740,000) MANTECH (550) $560 (est.) LABOR $2,586 MMIC EMD (19,000) OTHER $2,233 MATL 19901990 19951995 20002000 20052005 20102010 Part Counts Per Site
Affordability achieved by: • Leverage commercial industry RF electronics
• Processing costs continue Moore’s law Count Part decline • OSA architecture enables staged insertion of new technology 1998 2002 2003 2006 2009
8 MPAR Challenges being addressed by Industry…
Parameter* Technical/Cost Assessment* # of T/R modules per face
Number of Frequency Channels
Dual Polarization
Bandwidth
T/R RF Power
Number of Concurrent Rx Beams
Software Complexity
Size, Weight constraints
Prime Power Constraints
…Affordability is key
* Reference Table 6-1 from FCM-R25-2006 Federal Research and Development Needs and Priorities for Phased Array Radar June 2006 9 What can Government and Industry do to advance MPAR?
• MPAR system concept optimization studies – System concept definition – Establish system level performance requirements – Refine focus on targeted risk reduction • Encourage industry participation
