ABSTRACT: Feature extraction and target recognition suffer from a lack of a reliable model for both exploitable target features and the electromagnetic signature they possess. Signature data are often hard to interpret and invert to recover the target robustly. Bayesian learning approaches to statistical pattern recognition are based on the use of training sets of inputs and outputs, a data mode ...

ABSTRACT: Experimental testing of dynamic models has been performed for more than 50 years and a wealth of data exists for individual models. However, this data is often either restricted as proprietary or is not suitable for CSE tool validation as a result of incomplete model or test information. Mainstream Engineering proposes to design, fabricate, and test a scaled fighter for aeroelastic ...

ABSTRACT: A recent study by the National Research Council found that sophisticated statistical techniques are finding their way into DoD operational test design, but that current DoD practices are still substantially behind the state of the art. The study concluded this has resulted in inefficient test designs, wasted resources, and less effective acquisition decision making. US Air Force test an ...

In this STTR Phase I project, CFD Research Corporation and University of Nebraska at Omaha will develop a preliminary computationally-driven first-principles framework for discovery and design of non-RE-containing alloys for high temperature applications. While rare-earth (RE) based alloys have played a pivotal role in modern defense and high-tech industry, sustainability of RE-based materials is ...

ABSTRACT: Physical Sciences Inc. (PSI) and the University of Tennessee Space Institute (UTSI) propose to develop an innovative system to measure and control the cryodeposit layer thickness that develops on cold surfaces in cryogenic radiometric calibration chambers. The system includes: 1) an in-situ, interferometric-based instrument to monitor the cryodeposit layer thickness, 2) a mitigation sy ...

In this Phase I SBIR proposal, Reactive Innovations, LLC will demonstrate the technical and economic viability of a room temperature environmentally friendly technology for extraction and separation of light rare earth metals (lanthanides) with improved efficiency. Rare earths currently require multiple separation steps to yield high purity material. Decreasing the number of separation processes ...

ABSTRACT: Current and projected limitations on the maximum power from a high power single mode fiber laser amplifier impose architectural limitations on a high power phased array laser weapon system. Prior studies strongly indicate that when faced with this limitation the optimal approach is (to borrow the term for Paul McManamon) a Phased Array of Phased Arrays (PAPA) geometry wherein large(r) ...

The development and integration of three unique and innovative algorithm prototypes into a"Fused Track and Characterization Schema"are proposed. This Schema will encompass the determination of signatures and characteristics of objects that can be identified by RF and EO/IR Sensors in order to enable multi-sensor data fusion and correlation. The first algorithm, the"3D Pose Estimation"Algorithm, p ...

ABSTRACT: Remote optical detection of ground vibrations could potentially enable discovery of subterranean and camouflaged activity. The basic challenges are to acquire a detailed physical understanding of the detected signal and develop a system at reasonable cost with sensitivity to extremely small fractional light modulations. Under this effort Spectral Sciences, Inc., in collaboration with ...

The proliferation of sophisticated ballistic missile systems threatens the ability of the U.S. to project military power and defend its deployed forces, its allies, and possibly even the homeland. Adversaries continue to improve their ballistic missile technologies, and are expected to incorporate multiple warheads, countermeasures, and decoys. The AEGIS systemthe sea-based component of the U.S. b ...
