ABSTRACT: The Phase II technical objectives follow directly from the Phase I effort, where all tasks necessary for RF photonic receiver fabrication were demonstrated. The Phase II effort will pursue two major objectives: 1) further development of SEO100 EO polymer based chips, packaged devices and arrays in collaboration with University of Dayton (antenna designs), taking advantage of multiphoto ...

ABSTRACT: Shared Spectrum Company (SSC) partners with Virginia Tech (VT) to develop resilient and agile space communication systems using innovative cognitive radio techniques. The objective of this STTR Phase II project is to develop anti-jamming capability using frequency agility provided by Dynamic Spectrum Access (DSA) technology for satellite communications (SATCOM) systems. The SSC team foc ...

ABSTRACT: AdValue Photonics and University of Arizona propose to demonstrate the capability of fabricating wavelength division multiplexers (WDM) for high-power fiber laser applications. It is based on AdValue Photonics"unique fused fiber technology using large-mode-area (LMA) fibers. Both polarization-maintaining (PM) and non-PM LMA fiber WDMs will be fabricated. By the end of Phase I, two proto ...

ABSTRACT: The innovation proposed is a computationally-tractable, physics-based, portable turbulent combustion modeling strategy for application to a wide range of Air Force aero-propulsive systems, including augmentors, liquid rockets and scramjets. This modeling strategy will be implemented within an Application Programming Interface (API) library suitable for easy integration within Air Force ...

ABSTRACT: The Air Force Phase I program would develop and demonstrate semiconductor nanomembrane (NM) based sensors and arrays for high frequency pressure measurements, using SOI (Silicon on Insulator) NM technique in combination with our pioneering HybridsilTM copolymer nanocomposite materials. NanoSonic would work cooperatively with Virginia Tech to develop an improved mechanical and electrical ...

ABSTRACT: A new approach to multisensor fusion is proposed that utilizes a knowledge-aided (KA) multi-physics model as the main fusion engine, as opposed to traditional purely statistical methods. The new Multi-Physics Sensor Fusion (MPSF) is enabled by advances in high performance computing, knowledge-aided (KA) processing, and new techniques in multi-physics modeling. Traditional sensor fusion ...

ABSTRACT: SSC and VT develop algorithms and approaches to manage uncertainty in dynamic spectrum access (DSA) systems for small satellite constellations. We use various DSA rule sets such as sensing, database, and monitoring systems to reduce the uncertainty on a systems level. We investigate uncertainty modeling using Dempster-Schafer theory to build belief, disbelief and ignorance maps of spe ...

ABSTRACT: Due to scarcity of spectrum, Dynamic Spectrum Access (DSA) becomes a needed technology to improve the utilization of electromagnetic spectrum for DoD satellite communication. However, current DSA approaches are developed for terrestrial communications without addressing the unique challenges for SATCOM environments such as error-prone spectrum sensing, high mobility, and large coverage. ...

ABSTRACT: Global InfoTek, Inc. recognizes both the unique technical challenges associated with security in Cyber-Physical Systems (CPS), and the critical importance of such systems across the DOD. Our solution consists for four critical elements: 1. A permissive, kernel-level, whitelisting approach. This identifies unexplained changes to executable code in a target CPS, using an abs ...

ABSTRACT: A cyber-physical system (CPS) is a system that features a tight combination of, and coordination between, the system"s computational and physical elements. Today, a pre-cursor generation of cyber-physical systems can be found in areas as diverse as emerging and future combat systems, air-space-cyber activities, as well as smart buildings, bridges and other structures. CPS security mu ...
