The utility of continuously tracking vehicles in a battlefield has been demonstrated during the Gulf War and other recent conflicts. However, the ability to achieve reliable continuous tracking in many environments will require the use of FOPEN radar andefficient use of sensor resources. In this effort we extend current research to include heterogeneous terrain and apply this model to simulations. ...

This proposal will enable the most efficient integration of NASA?s semiconductor lasers into strategic optical systems. To protect laser lifetimes and increase performance, these lasers will require isolators to protect them from back-reflections, similar to the isolators in all fiber-optic networks. This work proposes to monolithically integrate magneto-optical isolators with semiconductor platfo ...

In this project, a lightweight membrane mirror device will be integrated into an adaptive control system, capable of correcting static and dynamic primary-mirror shape errors in a space-based telescope. The core innovation will be the use of a multi-zone, deformable mirror fabricated by thin-film surface micromachining. Contour shape of the mirror membrane will be controlled by an array of electro ...

Interpretation of video imagery is the quintessential goal of computer vision. The ability to group moving pixels into regions and then associate semantic labels with those regions has long been studied by the vision community. Only recently have thecomponent technologies matured sufficiently to make this goal attainable for well-defined scenarios. We propose a system for semantic interpretation o ...

The innovation is a compact, UAV compatible, high-definition hyperspectral imaging system. The system concurrently-acquires a hyperspectral image using a compact grating imaging spectrometer and a much-higher spatial resolution color photographic image using a portable, measurement-grade, high-definition CCD camera (2,000 x 1,312 pixel). The spectral resolution of the hyperspectral image is better ...

The proposed R/R&D effort will obtain new improved, in situ measurements of vegetation using a computer-based fluorescence imaging system that images and processes the plant's cellular energy emissions to quantify and diagnose the plant's photosynthetic pathways. With multi-spectral bandwidths and image processing which increase the system's sensitivity, fluorescence-imaging diagnoses early plant ...

Aeroservoelastic (ASE) modeling and vehicle stability analysis are twomajor concerns in the accurate prediction of flight characteristics ofgeneric hypersonic vehicles (GHVs). We propose to develop an ASE modelingand vehicle stability analysis toolkit. System Identification (SI)-basedblack box models of CFD solvers is the primary focus in Phase I.Bifurcation and Chaos Theory Methodology (BACTM) is ...

The overall goal of this project is to develop a robust autonomous intelligent real-time system for Uninhabited Aerial Combat Vehicles (UCAV) to achieve the desired flight performance by integrating effective Health Monitoring and Failure Detection and Identification (HM-FDI) with optimal control strategies to accommodate unanticipated failures and multiple modes of operation. SSCI has already don ...
