Phase I objective is to demonstrate the feasiblility of our proposed approach to minimize the defect and dislocation size and densities in Si substrate based HgCdTe epitaxial layers with a cut off wavelength of ~10 microns at 77 K. Phase II effort will validate our approach with demonstration of large area Si substrate based HgCdTe epitaxial layers with area in excess of 25 cm2 and in addition dem ...

This proposal describes a software system to help system engineers understand the true needs of the stakeholder for M & S tools in MDA.. The manual process used today takes valuable time with several iterations and the quality of the output is largely influenced by the experience level of the system engineering team involved. The proposed software system will use the Discovery Machine Modeler to ...

System requirements elicitation is a time consuming process with an extremely high penalty for errors. Mistakes made in the requirements phase will cost 50 times more to fix while they are uncovered in the production phase as compared to fixing them in the requirements phase. VIStology and Northeastern University are proposing to develop an approach for supporting the requirements elicitation phas ...

In order to counter emerging threats from the Middle East and Southeast Asia, the Ballistic Missile Defense System (BMDS) is acquiring new sensor (e.g. AN/TPY-2 and PTSS) and weapon technology (SM-3). As these new technologies becomes fielded, the BMDS's Command, Control Battle Management and Communication (C2BMC) component must be able to correlate objects between multiple sensors. Inheren ...

In Phase I, TSC and the University of Connecticut developed an innovative track handover algorithm which combines estimated rotational motion states with measured radar or IR data to correlate tracks. Rotational motion states are derived from S-band or X-band radar measurements using TSC"s Static Pattern Reconstruction and 3D Radar Imaging algorithms. The Rotational Motion Handover algorithm dem ...

The proposed effort will further refine the adaptive model-based estimation and control guidance law developed during the Phase 1 effort to work in a two-tier algorithm with an agile, game-theoretic guidance law that is immune to the acceleration of the target. The two-tier approach is used to bring the intercept vehicle close to the target while conserving fuel but still obtains good minimal mis ...

Radio Frequency Directed Energy Weapons (RFDEW) are maturing sufficiently to become a threat to sensitive circuits onboard military platforms. With a large number of active elements, Ballistic Missile Defense System (BMDS) phased array radar units are particularly susceptible and require improvement over the current state-of-the-art in limiter technology. This is particularly needed in the develop ...

Quallion LLC is pleased to submit this proposal in response to the solicitation for"Modeling of Lithium-ion Cell Performance."This proposal focuses on the area of interest relating to"accelerated life testing for LEO because the processes that occur at the anode and cathode at high DoD"s (60+%) are poorly understood as to how they relate to low DoD"s (30% and lower)."Quallion has developed a refer ...

Rechargeable Lithium-Ion (Li-Ion) cell technology is attractive for MDA space satellites. But, because this technology is relatively new and is still evolving, its performance and behavior must be characterized by laboratory life testing that is very time consuming and expensive. A requirement for a 10-year real-time cell life test could delay the incorporation of Li-Ion cell technology into MDA s ...

Global Aerospace Corporation (GAC), in collaboration with NASA"s Jet Propulsion Laboratory (JPL), plans to develop a prototype, high-fidelity, first principle-based, comprehensive, and user-friendly software model to predict the long-term behavior of advanced rechargeable lithium batteries in aerospace applications. This Li-Ion battery operation model will 1) incorporate in one tool, for the first ...
