In this proposal, Alphasense, Inc. details the development of a novel microwave NDE sensor for defect inspections in silicon nitride bearing balls. The key innovations of this proposal include the following: a) the use of the spherical bearing ball as a dielectric resonator, thus enabling us to correlate the resonance characteristics of the bearing ball with various defects; b) the measurements in ...

Solution Engineering, Inc. (SEI) proposes to develop and demonstrate a prototype real time tracking system that supports robust multiple target tracking in an urban environment.  The approach will focus on increasing the robustness of the core feature tracking algorithms, utilizing target invariant characteristics to extend the ability to track, coast, and reacquire targets.  In addition higher ...

The foundation of any counterspace capability is space/counterspace situation awareness. Existing AFRL/VS funded efforts have established a foundation for robust, multi-level situation awareness through multi-source, multi-level, data fusion. However, situation awareness is only useful to the extent that it informs response to threats, whether natural or man-made. AFRL/VS Space Awareness & Respons ...

High speed fiber grating diagnostic systems may be used to measure the velocity, position and pressures associated propellant burning during a rocket motor firing. This Phase I SBIR is directed toward the demonstration of the feasibility of this type of system which may also be used to measure strain, pressure and moisture in the propellant region prior to firing.

Over the past few decades, computational electromagnetics (CEM) researchers have been making steady progress towards the development of efficient algorithms, such as the Method of Moments (MoM), for simulating scattering from electrically large targets. Unfortunately, such techniques have proved too computationally demanding because they require the solution of an often very large and dense matri ...

Photonic crystals have led the way for miniaturizing application specific optical integrated circuit (ASOIC) to a scale comparable to the wavelength of light which in turn made them a good candidate for next generation high-density optical systems and interconnects. Polymer based Photonic Crystal structures have potential applications in optical integrated circuits, optoelectronics, optical switch ...

Field Programmable Gate Arrays are widely recognized as an attractive technology for satisfying the needs of U.S. Government Crypto Modernization programs. However, FPGA technology creates some interesting challenges in terms of reliability and assurance of crypto implementations. In the late 1990s, the National Security Agency recognized the need to significantly improve the state-of-the-art for ...

The threat posed by remote cyber attacks has grown every year, with nation state attacks being the hardest to detect and blunt. A common cyber attack method against remote systems is the code injection attack, where the attacker finds flaws in a remote application then forces the application to execute injected code. Code injection attacks can give the attacker unlimited access to the attacked sys ...

Experimental tests in Phase I have shown the fuze shock absorber system capable of reducing shock peaks by a factor of three, and the associated jerk by an order of magnitude. The Phase II work will be devoted to exploring the performance space of this jerk-reduction system as a function of its material properties and physical configuration, as well as the fuze mass. LRK Associates will design a ...

The Phase I work has shown the technical feasibility of creating new, equivalent-accuracy algorithms for optical simulation with smaller operations counts than existing Fourier methods. These will be helpful in speeding up extended scene imaging simulations used in laser weapons' systems performance evaluations. However, the computational efficiency advantage of these new algorithms over Fourier ...
