Nuvotronics is proposing to Navy SBIR number N132-087 to develop novel high efficiency, light weight, low manufacturing cost 94 GHz antenna modules toward future Active Denial Technology systems. RF passive components based on waveguides are generally very low loss but are heavy, expensive to machine at high frequency and bulky. Components based on substrate material such as ceramic or printed cir ...

A rugged design of high power, high gain, low-loss transmitter with low profile is proposed to develop and test in Phase I. The design is based on self-focusing effect of surface waves leaking from a tapered, multi-wavelength-long, slow-wave structure. High directivity of the antenna is provided by coherent spatial interference of these waves enhanced by a horn, bandgap segmentation of the structu ...

In order to address the Navy"s need for a new mask-on mobile device to train aviators for altitude exposure (hypoxia training), ChromoLogic LLC (CL) proposes to develop a Portable Hypoxia Training (PHYTR) system. The PHYTR system will be based on a novel concept that takes ambient air and produces user specified oxygen content through a cyclical fluid exchange process. When completed, the PHYTR sy ...

We propose to develop a SAASM ultra-tightly-coupled GPS/INS system that provides 75 dB of AJ during track and greater than 60 dB of AJ during acquisition. The system relies on existing SAASM boards coupled with navigation software developed by Coherent Navigation. Our system is designed for UAVs and other airborne platforms.

Range testing of new airborne military electronic systems is quite costly in terms of the test-range facilities, equipment, and operations. Broadband RF collection systems are needed to record wide swaths of the relevant Electromagnetic Environment (EME) so that these Systems-Under-Test can be cost-effectively and accurately tested in a lab setting. Because of the wide frequency range, a large dyn ...

ATA Engineering proposes to simulate complex interior and exterior flowfields of hot, supersonic aircraft engine nozzles by applying a novel dynamic hybrid RANS/LES (DHRL) modeling framework coupled to the Loci/CHEM (CHEM) finite-volume flow solver. DHRL is code- and turbulence model-independent. It dynamically determines the appropriate interface between large eddy simulation (LES) and Reynolds A ...

Arete Associates proposes to develop novel techniques to exploit radar-identifiable small boat wake signatures associated with unsteady motion and turbulent signatures in addition to enhancing existing methods to exploit steady-state wake characteristics. Using advanced nonlinear hydrodynamic techniques, Arete will develop innovative advanced modeling of steady, unsteady and turbulent wake signatu ...

3um fiber laser sources suffer from limitations in the fiber, such as high loss. Fluoride fiber has been utilized as a solution for this problem, but this suffers from a low damage threshold among other issues. SA Photonics in collaboration with the LLNL Fiber Laser Group has proposed a hybrid solution to getting around this problem. Our 3um source has the advantages of being a rugged, monolithic ...

Rapid response missions to remote, unknown areas are becoming a primary focus for U.S. military forces. These missions require time-sensitive development of intelligence from all available sources including open source data, historic imagery, and live collections. Capabilities currently exist to extract low-level information (i.e. entities, relationships, and actions) from these large scale data s ...

Representing knowledge in a triple store is trivial, yet querying and visualizing the resulting knowledge is difficult and inefficient when the number of triples is large. Needing to understand the data models from each of the contributing processes and how these data models overlap or interact further complicates this problem. Visualization tools for knowledge stored in the Resource Description F ...
