MPAR Cost Evolution What Drives Cost? Concept of Operations (CONOPS) Drives Operational Requirements (User Needs) Drives Performance Requirements (Characteristics) Scale Drives Radar System Architecture & Design MPAR Cost Drives
MPAR Requirements • Assertions • Operational Requirements associated to MPAR can not be fully developed without a Concept of Operations (CONOPS) for Radar • Mission Gaps can not be sufficiently identified without operational requirements • Operational Requirements will drive Architecture/Design which will drive Cost • The MPAR-WG must avoid the pitfall of a bottom-up approach • starting with technical requirements for existing radar will lead to ill-formed requirements for MPAR • Require a fundamental change in requirements thinking • e.g., 4.8 sec track update not a requirement • What does the user need?
MPAR Cost Reduction • What can we do to affect cost? • Scan Strategy Study • What are the resources needed to accomplish what must be surveilled? • How often does it need to be surveilled? • Can we do it cheaper (simplified beamformer network)? • Beamwidth Study • Increasing beamwidth decreases the number of T/R Modules decreasing cost • What is acceptable to the weather community? • Technology Investigation • Semi-conductor materials • Commercial Parts
MPAR Cost Influences • Several influences to radar system cost • T/R Technology • Maturity • Economy of Scale • Commercial Packaging • User Operational Requirements • Scan Strategies • Beam Characteristics • Desired Performance
Electronics cards TR-modules Analogbeamformer Downconverters and A/D Power supplies, fans, etc. Digital backplane Antennae (4x4 at 5 cm spacing) Low-loss microwaveinterconnect cables Advanced MMIC Design R&D Risk Reduction Efforts • Established/implemented MPAR pre-prototype technology demonstration program • Exploring low-cost commercial technology (e.g., semiconductor materials, fabrication, etc.) • Evaluating multifunction system concept • Developing advanced active array architecture (digital beamformer, overlapped sub-arrays) • Researching advanced surveillance techniques • Completed initial radar system concept definition (e.g., radar coverage analysis, scaled gap-filler concept) • Identifying major cost issues and investigating mitigation strategies • Developing MPAR Concept of Operations
R&D Risk Reduction (cont’d) • Conducted engineering studies • Evaluation of MPAR Benefits for FAA Weather Services (in progress) • Evaluation of MPAR Benefits for FAA BU Surveillance Services (in progress) • Radar Resource Utilization (weather vs. aircraft) • MPAR Cost Estimate & Technology Assessment (and Cost Model) • Pulse Compression Study
Pathway for Future Risk Reduction • Continue researching technology: • Affordability • Capability • Performance • Continue to establish partnerships with other Government Agencies, Industry and Academia • Develop MPAR Prototype to execute research tasks necessary to meet R&D objectives
