WITH OXIDES LIKE THORIA HAS BEEN KNOWN FOR A LONG TIME. HOWEVER, OXIDES ARE NOT WET BY METALS, SO WHEN OXIDE DISPERSION HARDENED METALS ARE MELTED, THE DISPERSED OXIDE SEPARATES AS A SLAG AND THE ADVANTAGES OF DISPERSION HARDENING ARE LOST. IN THIS PROPOSAL, A NEW APPROACH TO OXIDE DISPERSION HARDENING IS SUGGESTED, THROUGH THE USE OF METALLOPHILIC COLLOIDAL OXIDE PARTICLES. SPECIFICALLY, A FUNDAM ...

Many hardware trojans depend on (a) the ability of an attacker to have an accurate model of the target system and of key software used on that system and (b) identification of one or more deterministic trigger conditions with low observability (i.e., conditions that evade detection by traditional scan- or ATPG-based testing methodologies but that can be exercised on demand via external stimuli). ...

It is quite common for a group of GPS users to operate in close proximity and in a denied or degraded GPS environment as typical in urban canyon and heavily forested environments. Using the traditional GPS receiver approach, individual or all users may be denied the ability to navigate in such an environment, even though each user may be intermittently receiving useful satellite signal information ...

ABSTRACT: The Air Force is seeking advanced seekers that integrate multiple modes of detection. In particular, this SBIR will pursue development of a Semi-active Laser (SAL) sensor and a passive infrared (IR) sensor into an integrated seeker for precision and agile munitions. The enhanced capability is required to address military operations in difficult environments such as urban terrain, to ma ...

Many custom and hybrid integrated circuits (ICs) and custom electronic components cannot bemodeled in simulation software because of their complexity and/or lack of technical data.TPS developers need to use a hardware modeler for these types of integrated circuits.The proposed WesTest Hardware Modeler will be compatible with LASAR and the VDATS Di-Series digital subsystem.It utilizes the Teradyne ...

ABSTRACT: The Air Force has identified a need for efficient, lightweight, millimeter-wave transmitter development that supports future generations of bandwidth efficient military satellite communications and communications links between Remotely Piloted Aircrafts (RPAs), satellites and terrestrial terminals. As RPAs and associated battlefield sensors proliferates, requirements for additional mil ...

ABSTRACT: As intelligence and sensor systems become more complex, the amount of data being transferred increases. Naturally, this calls for a higher bandwidth communication backbone in the field. This demand has spawned a requisite for an airborne antenna supporting satellite communication at V/W band. The target platform for this antenna is a large UAV, such as the Predator or Reaper. The ma ...

Modern Directed Energy (DE) missions require target engagements at low elevation angles and long ranges.These engagement geometries require propagation through distributed-volume turbulence. To correct for distributed-volume turbulence effects, an estimation of the turbulence along the propagation path is required. Correcting for these image aberrations will improve the quality of the target image ...

Through the execution of our Phase 1 effort, Nutronics, Inc. and Montana State University developed an improved means to optimize the Pellizzarri cost functional for coherent imaging using digital holography. Our algorithm developed during the Phase 1 effort accelerates convergence times by a factor of 20-40 for the majority of scenarios evaluated. Our proposed Phase 2 effort has a two-fold focus: ...

Nutronics, Inc. and Montana State University propose to develop and evaluate computational methods for a Volume Digital Holographic Wavefront Sensor (VDHWFS).VDHWFS based imaging offers the potential to provide the equivalent of wide field of view adaptive optics (AO) compensated imaging, but without the added complexity of AO components and hardware.Recent result for coherent imaging developed by ...
