Abstract:The ability to explore, analyze, and find hostile actions/intent behavior within this data is a complex task and requires learning of motion sequence temporal patterns from long term tracks of multiple vessels of interest. There is, therefore, a major need to develop robust, efficient, and reliable… more
Abstract:This effort proposes to determine the feasibility of and continue development of innovative 3-D inverse synthetic aperture radar (ISAR) imaging techniques for maritime vessels. Traditionally, 2-D ISAR image frames have been used individually to classify vessels of similar classes with limited… more
Abstract:The propose effort will determine the feasibility of and continue development of innovative feature-based adaptive constant false alarm rate (FA-CFAR) techniques to detect slow moving and low radar cross section (RCS) maritime targets in challenging clutter environments. A first order approach… more
Abstract:The proposed work extends ongoing RDRTec maritime classification aids (MCA) and feature-aided tracking development activities that utilize high range resolution (HRR) and inverse synthetic aperture radar (ISAR) by adding combined feature vectors consisting of the hard body, water wake, air wake,… more
Abstract:Collision Avoidance (CA) radar systems are required for compliance with the Navy"s operational requirement for Sense And Avoid (SAA) for Unmanned Aerial Systems (UASs). The Radar Airborne Collision Avoidance System (RACAS) is designed to provide CA capabilities for both Triton and Fire Scout.… more
Abstract:This effort will complement the C-RACAS transition to both Triton and Fire Scout by performing risk reduction activities addressing stressing environments and scenarios using simulation, and early data collection with prototype RACAS and C-RACAS hardware. In addition, it will address Triton"s… more
Abstract:This effort proposes to design, develop and fabricate prototype SiGe MMICs that when combined with GaN MMICs forms the basis for additional simultaneous modes and more efficiency for the C-band Radar Automatic Collision Avoidance System (RACAS). The addition of these MMICs will enable digitally… more
Abstract:Future experiments in nuclear (and particle) physics will require advances in detector technology in order to carry out planned measurements of QCD, electroweak interactions, studies of fundamental symmetries, understanding the spin properties of nucleons, and many other physics topics. Among the… more
Abstract:Extreme high vacuum (XHV) systems are characterized by very low gas pressure and a small outgassing rate of the system surfaces. The pumping techniques required to reach XHV conditions impede further reduction of the XHV pressure by either re-emitting chemically-stored pumped gas or allowing back… more
Abstract:The objective of this work is to quantify the reduction of biofilm formation in a water distribution system resulting from an organoselenium surface coating on stainless steel pipes and fittings. Differentiated from currently marketed antimicrobials, selenium, is permanent, catalytic and does not… more
Abstract:Project Summary We aim to introduce to the hearing-assistive device industry the first commercialized microphone that combines all three axes of acoustic pressure gradient onto a single silicon chip. We expect the technology to empower the signal-processing community with a new tool which, when used… more
Abstract:The U.S. Army has a need for cheap, high quality nanosilicon powder. With similar energy density and better aging effects than nanoaluminum, silicon is an excellent candidate for use a metal nanofuel. In Phase I, Systems and Materials Research Corporation (SMRC) demonstrated a scalable method for… more
Abstract:ABSTRACT: Each fastener that is installed during the aircraft assembly requires a hole to be drilled, and those holes filled with either rivets or threaded fasteners. To add difficulty, most fasteners must have sealant applied to the hole, and interference fasteners must be inserted using an… more
Abstract:ABSTRACT: Corrosion is a serious problem affecting the longevity, safety, durability, and affordability of military and commercial aircraft. Despite strict implementation of MIL and ASTM standards for aircraft Outer Mold Line (OML) coatings, corrosion is frequently observed during maintenance… more
Abstract:Systems & Processes Engineering Corporation (SPEC) and Texas A & M University (TAMU) propose a space hardened, compact, low power, high definition six-dimension (HD6D) LADAR for remote sensing. This modular situation awareness HD6D LADAR can be configured by platform and mission to support… more
Abstract:Systems & Processes Engineering Corporation (SPEC) proposes a Wind Measurement LIDAR whose sensor assembly is composed of SPEC Gen IV LIDAR seeker, with 12.8 Mpps imaging rate, modified with a laser with ultra-narrow band seed, AOM and modulator, to allow air current Doppler detection beyond 3km… more
Abstract:Recently, the F-35 program experienced fatigue cracking in a low pressure turbine blade inside the F135 engine from recrystallization (RX). These problems cost the program time and money, strain the political capital necessary to sustain a large weapons program, and undermine the confidence of… more
Abstract:Payload stored in multiple all-up-round canisters (MACs) critical to Ohio- and Virginia-class sub missions is susceptible to damage from excessive shock and vibration loading. TRI/Austin proposes to investigate a state of the art lateral missile support system to resolve this issue. A preliminary… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
