Systems that operate in constrained environments depend on the acoustics in several ways. Harbor defense systems detect intruders (peopleand/or vessels) by either listening for their noises (passively) or by pinging on them and detecting their echoes (actively). Furthermore, suchsystems may also form the equivalent of an underwater cell phone network using sound to carry the information. The acous ...

SA Photonics has developed a concept for our Multiple Optical Beam Landing System (MOBLS) to provide autonomous landing of aircraft in RF denied environments. MOBLS utilizes multiple, redundant methods to determine the real-time location and bearing of the aircraft relative to the carrier-based landing strip. By having built in redundant modalities, MOBLS provides highly reliable landing informati ...

In this Phase II STTR effort, nGimat will partner with the University of Kentucky (UK) and 3M/Ceradyne to continue development of W-scandate cathode composite materials. Compared to conventional M-type cathodes, these composite scandate nanomaterials will enable longer cathode lifetime by lowering the required operating temperature. nGimat is an established and successful powder manufacturing comp ...

Overhead Persistent Infrared (OPIR) platforms observe challenging threat and scene phenomenology. Toyon Research Corporation developed an image processing framework for clutter estimation/suppression and track-before-detect to jointly detect and track targets. The Target Extraction and Conjoint Tracking application, developed under initial Phase II funding and demonstrated using real-world data so ...

Composite materials have emerged as the materials of choice for increasing the performance and reducing the weight and cost of military aircraft. Nevertheless, manufacture of composite parts still poses numerous difficulties which can result in premature curing, degradation in thin cross-sections, incomplete curing in thick counterparts or build-up of internal stresses. Experimental investigations ...

An integrated program of fundamental research, software development and technology transition to Navy target platforms for computationally efficient yet accurate prediction of turbulence interactions involving disparate length scales has been proposed and is underway. The fundamental research will be conducted at Purdue University and provide a critical modeling component for turbulence resolving ...

Building on our prior research in group discovery and tracking, we propose to develop new algorithms for predicting future behaviors of social media groups. These algorithms will be based on emerging social interaction theories and new computational models of group dynamics at multiple levels, from individual roles and interactions to aggregate trends within and across groups. Our approach takes a ...

Vacuum Process Engineering, Inc. (VPE), in collaboration with the University of California, Davis (UC Davis), proposes to develop and quantitatively verify a large scale production process for scandate tungsten nanocomposite powder to be used in high current density and long life cathodes during the Phase II effort. The plan for implementation of the large scale production process at VPE with powd ...

Navy talent management must evolve to keep pace with the demands of new technology, new battlefields, and new enemy tactics in the face of budget reductions. It must fully utilize the existing skills of Navy personnel, and it must optimize the detailing and subsequent training of personnel to reduce costs and maximize job effectiveness. Transfer is key to talent management; optimal talent manageme ...

SI2 Technologies, Inc. (SI2) proposes to accelerate development of printed, high-efficiency phased arrays operating at Navy-relevant frequencies. The proposed development effort will include optimization of the array printing techniques from Phase I to meet the Navys phased array performance goals. The printed arrays will incorporate both printed radiating elements and an innovative printed packag ...
