Abstract:Under this SBIR effort, we propose to develop a system architecture that provides improved accuracy and availability under adverse conditions for networked GPS receivers operating collaboratively using a GPS Distributed Aperture Processing (GDAP) approach. The proposed collaborative approach… more
Abstract:Prior research has shown the advantages that can be employed by using Digital Storage Receivers to allow processing of the GPS signals after a submarine has submerged to reduce the time spent on surface for covert operations. Under this SBIR effort, we propose to design a Submersible GPS Enhancement… more
Abstract:A dismounted soldier or airman who turns on his GPS receiver on the battlefield depends on a quick and accurate navigation solution, even in areas where the GPS signals may be degraded. The intent of this SBIR program is to address this requirement by providing military GPS receivers with an… more
Abstract:Emerging Cognitive Radio (CR) technologies are allowing the development of radios that can"observe,""orient,""plan,""decide,""learn,"and"act"to adapt the performance of a Software Defined Radio (SDR) in response to stimuli in the external… more
Abstract:ABSTRACT: The Current generation of military GPS User Equipment (UE) uses significantly more power than a commercial GPS unit. There is a desire to develop operational techniques and lower power devices to increase operational use of hand-held military GPS devices. A lower power alternative to… more
Abstract:Non-invasive methods are required to measure the turbulence in supersonic jet plumes in 3-D with high temporal and spatial resolutions. The turbulent supersonic jet plume changes rapidly both in space and time, and hence any viable approach must acquire the entire 3-D velocity field at even faster… more
Abstract:Military common laser range finders (CLRF) currently use a direct viewing binocular augmented with AN/PVS night vision eye pieces with infrared cutoff at about 900 nm, incapable of detecting either the eye-safe laser range finder beam or the laser designator beam. The CLRF needs an all-light-level… more
Abstract:Ground resolution is a critical parameter of an airborne surveillance system, whether it is a ground radar or an optical camera. The synthetic aperture (SA) method has proven extremely successful in Radio Frequency (RF) radars to achieve spatial resolution significantly higher than that of the… more
Abstract:Using predictive tools developed in previous work, Dominca will design, build, and test layered-media filters to reduce the transmission of 2 kHz and higher frequencies into accelerometers that are used in explosive and impact events. The size of these external filters will be kept small by… more
Abstract:"The widely distributed water infrastructure system provides drinking water and waste water treatment for human life and the environment. A significant amount of water infrastructure network has served the public for decades and is encountering aging problems. Water leakage resulting from aging… more
Abstract:The recent use of materials, such as 5xxx-series aluminum in new ships is posing new challenges in inspection for the Navy; as future performance of these materials over time is not as well known. Current state of the art off the shelf techniques have not proven to be viable options for monitoring… more
Abstract:An ultrasonic guided wave phased array approach is proposed for the rapid inspection of aluminum ship hulls below the waterline. With the proposed guided wave phased array technology, a centralized probe is used to steer a beam of ultrasonic energy around the hull structure, like radar. The gathered… more
Abstract:Advanced composite materials are currently being considered for use in propellers on Navy ships. However, limited in-service data exists on the performance of these materials which leads to excessive pre-service testing and a tendency to overdesign components. Therefore, to reduce the excessive… more
Abstract:The military faces a challenge with regard to temporary bridge inspection, as most existing monitoring solutions are designed around the monitoring of permanent bridge structures. These temporary structures are now being used in semi-permanent installations and are experiencing loads and cycles far… more
Abstract:The accumulation of ice on rotor blades while in-flight has been responsible for millions of dollars in damage and loss of life. Current blade ice protection systems are thermal-based and have very demanding power requirements and, therefore, are typically never used and in some cases permanently… more
Abstract:There currently exists a need to develop new technologies for real time structural health monitoring (SHM) of composite armor panels on ground vehicles in order to inform decision makers on board or at remote locations as to the severity of damage that may occur. FBS, Inc. proposes the development… more
Abstract:Computing systems built on identical foundations (hardware, operating systems, etc.) will be vulnerable to the same attacks. To avoid widespread failures, techniques have been sought for introducing"synthetic diversity"into systems. The best studied are low level randomization… more
Abstract:ABSTRACT: Despite existing security efforts, DoD networks are susceptible to attack and compromise. For critical missions, it is necessary to"fight through"cyber attacks in order to achieve mission objectives. Such a"survivable"network would be capable of carrying on (in a… more
Abstract:ABSTRACT: Analysts must determine the proper response to an alert produced by an anomaly detection system. Currently, analysts must manually generate queries to other intelligence sources and then search by hand through the results to find evidence relevant to the alert. This is a slow and… 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.
