One of the limiting factors for the development of advanced MDA related radar systems technology is the ability to test new concepts in an operational environment. Simulations, advanced modeling and range tests all provide valuable insight into the expected behavior of these systems during operations but there is no substitute for multiple tests of developmental systems against real targets in the operational environment. For missile defense, this requires flying re-entry vehicle (RV) like systems in threat trajectories and maintaining on-orbit targets for routine testing, as required. This type of capability would allow technology developers to continuously refine and adjust their concepts until they have optimized system performance. This same capability also provides invaluable training for operational systems and their crews. Unfortunately launch costs and satellite target development expenses are currently preventing this scenario from becoming a reality. PSI will use their satellite-based Network Data Acquisition System (NDAS) as the foundation for a family of low cost, quick response radar targets. The modular architecture of NDAS allows efficient upgrades of the existing system without redesign or requalification. We will provide MDA with a comprehensive decision matrix that defines a full range of options for radar target architectures
