In this proposal, Quadrant Engineering seeks SBIR funds to investigate development of an antenna element location measurement system suitable for compensating platform motions in airborne millimeter-wave antenna arrays. During Phase 1 we plan to evaluate three different approaches termed direct, active, and passive. In the direct approach, motion sensors attached to the antenna will be used to d ...

Achieving global awareness by automatically exploiting sensor data will provide tremendous advantage to the warfighter. However, camouflage, concealment, and deception (CC&D) can be effective countermeasures against surveillance systems. The most promising strategies for defeating CC&D exploit multiple sensor modalities, such as foliage penetration (FOPEN) synthetic aperture radar (SAR) and hype ...

In Phase I, ALPHATECH will define a model-neutral data structure and supporting access mechanisms that will provide interoperability between different modeling methodologies in support of large scale systems engineering. The model-neutral data structure will provide a common data representation of the model-specific data that is contained in the different modeling methods. The access mechanisms ...

In this effort ALPHATECH will develop algorithms for extraction of purposeful temporal-spatial patterns from moving vehicle data and demonstrate their efficiency on a set of simulated MPA scenarios. We apply unsupervised learning algorithms to find similarities between traffic activities. Traffic activities are constructed using ALPHATECH's multiple hypothesis tracking algorithm and grouping cor ...

Project will demonstrate the feasibility of combining signatures from multiple sensor domains to the problem of detecting, localizing and characterizing an underground facility. The Phase I effort will focus on establishing, integrating, and validating models for the source and propagation phenomenologies associated with electromagnetic, seismic, and acoustic signatures of mechanical and electro ...

Physical Sciences, Inc. (PSI) proposes to develop an etching tool based upon its patented Fast Atom Sample Tester (FAST) technology that addresses a critical processing problem faced by manufacturers of Bonded wafers. The fabrication process for bonded wafers results in a 5 mm wide strip of partially delaminated silicon along the perimeter of the 8-in. wafer which can serve as a source of unaccep ...

Modern fligt control systems rely on hardware redundancy to overcome failures of sensors and actuators. This is an expensive approach which does not make use of analytical redundancy present in a flight control system. Analytical redundancy is achieved by comparison of sensor outputs over time and across sensors using physical and identified models. We propose here methods to detect failures us ...

The overall goal of the proposed effort is to develop a fusion process that integrates SAR and hyperspectral sensor data in order to overcome the current performance limitations of single sensor automatic target cueing. In the Phase I effort, we will define a concept of operation for SAR/hyperspectral automatic target cueing. The nature of the imaging domains of SAR and HS sensor as well as the ...
