Abstract:The government has a current requirement to develop antenna systems which enable significantly increased GPS signal levels at specified pointing angles within the terrestrial footprint covered by a GPS satellite. Current and past GPS antennas are designed to provide a nearly constant flux density… more
Abstract:The future net-centric military provides enhanced battlefield awareness through wireless links between unmanned aerial vehicles, high-speed aircraft, rotary-winged platforms, and soldiers on the ground. To support this, platforms must accommodate a variety of antennas, not to mention traditional… more
Abstract:SATCOM On-The-Move (OTM) is one of the greatest operational and tactical advantages our troops have. The SATCOM terminals available pose a number of practical constraints resulting in less than universal usage. Traditional reflectors are high profile and difficult to integrate on aircraft and… more
Abstract:ABSTRACT: FIRST RF proposes a two pronged, pragmatic approach intended to provide antenna solutions for both small and large UAS platforms operating in L/S/C & Ku bands. Larger aircraft, such as the global hawk, have relatively fast cruise speeds where extra drag incurred by external components… more
Abstract:ABSTRACT: The proposed research will develop and validate a pragmatic approach to modifying existing ground station antenna systems to mitigate the spectral congestion. Furthermore, this solution is a natural building block for future AFSCN ground station capability growth and can serve to… more
Abstract:ABSTRACT: In the nearly 36 years since the first NAVSTAR GPS satellite was launched, GPS has grown into one of the most important and widespread technologies used by modern military and civilian systems. While the legacy GPS constellation continues to provide support for most military applications,… more
Abstract:A multiband SATCOM terminal solution is identified conforming to low profile rotary wing aircraft constraints. The architecture incorporates commercially available RF electronics and components in a unique package that precludes manual reconfiguration to support alternate SATCOM datalinks. This… more
Abstract:The objective of the proposed Phase I effort is to investigate the feasibility of a broadband High Power Radio Frequency (HPRF) antenna system that is capable of handling power of 1000 MW over a wide bandwidth including mid VHF to L-Band. It is desirable that the antenna occupy minimal volume when… more
Abstract:Frequency stabilized lasers are essential subsystems in many applications. Most importantly, they are used as flywheel oscillators in optical atomic clocks, as well as in many sensing and measurement systems, and some examples are down oil well sensing, laser radar and ranging in space, and… more
Abstract:High Precision Devices, Inc. (HPD) proposes to continue and complete development of the 25 kW Flowing Water Optical Power Meter for Laser Measurements begun under a Phase I SBIR award. In the proposed Phase II work described, HPD will complete mechanical and electrical subsystems, apply a ceramic… more
Abstract:Magnetic resonance imaging (MRI) has become a primary diagnostic tool in scientific research and clinical imaging. Despite the excellent image quality that can be obtained with today’s MRIs, images acquired using different MRI systems and during longitudinal studies are not reproducible, and… more
Abstract:In this proposal, HF Designworks (HFDW) and Alion Science and Technology (Alion) describe an approach for developing a concept for an operational console modernization tool. This tool will assess potential console designs in terms of several key factors: their adherence to human factors design… more
Abstract:ABSTRACT: This proposal addresses an important need of DoD and MILSATCOM for satellite based receivers operating at Ka-Band having multiple beams (as many as 30) capability. Many of these beams need to be independently steered. This has traditionally been a major challenge because, as will be… more
Abstract:Pure oxygen helps produce energy from coal with fewer greenhouse gases. Current oxygen production systems are expensive. ITN proposes an oxygen separation system using pulsed magnetic fields and polymer magnetic beads to separate oxygen from air for coal gasification plants/syngas production, as a… more
Abstract:ABSTRACT: Lexycom is proposing to design a miniature software-defined radio (SDR) transceiver for Remotely Piloted Vehicle (RPV) installations to support over-the-horizon TSPI/video relaying capability. Depending on the data traffic requirements, the proposed SDR can be equipped with several RF… more
Abstract:The E-Band frequency bands from 71 to 76 GHz and 81 to 86 GHz have been designated for satellite down- and uplinks, and have gained an increased interest. The wide bandwidth in excess of 1GHz allows the use of low order modulation schemes and simple receiver implementation. In other words, coarser… more
Abstract:Under the Phase I SBIR effort, we designed a Submersible GPS Enhancement and Playback System (SGEPS) to allow processing of the GPS signals after a submarine has submerged to reduce the time spent on surface for covert operations. This uses a Digital Storage Receiver (DSR) for capturing the GPS RF… more
Abstract:ABSTRACT: The objective of this effort is to investigate designs and possible options for a PNT Flexible satellite for GPS to enhance position, navigation, and timing (PNT) capabilities at a low cost using small augmentation satellites with limited payload. A desired feature to help overcome GPS… more
Abstract:ABSTRACT: In the event that the GPS constellation was unavailable, none of the current back-up navigation and timing solutions in place today such as inertial navigation, geostationary augmentation systems or cellular positioning solutions would function, resulting in catastrophic effect on… more
Abstract:ABSTRACT: Data compression schemes generally fall into two main categories: lossless and lossy. Lossless schemes promise to provide an uncompressed file which is identical before and after compression. As lossless schemes must be able to reconstruct every feature of the original file they often… more
Abstract:ABSTRACT: Numerica is proposing to extend its mature multiple hypothesis tracking (MHT) technology by providing additional estimation and data fusion algorithms to support improved space object detection, tracking, identification, and characterization. An extended program would aim to develop a… more
Abstract:Numerica is proposing a data-driven approach using modern state-of-the-art machine learning methods on sparse feature representations of non-resolved photometric data, for space object characterization, classification, and anomaly/change detection in support of threat identification and notification… more
Abstract:ABSTRACT: Detection of dim phenomena in images generated by short-wave infrared (SWIR) systems is complicated by the fact that objects of interest generate very faint trails on the raw imagery due to image artifacts; e.g., background clutter, sensor noise, internal reflections, atmospheric effects,… more
Abstract:Surface target tracking in the littoral environment is challenging because of a combination of issues including the presence of highly maneuverable small water-craft, occlusions due to waves or larger vessels, and the inability of any single shipboard sensor to maintain coverage on all objects at… more
Abstract:In this project a Radio Frequency Identification (RFID) temperature tag and reader system will be developed. The tag will be easily applied to large caliber ammunition such as artillery propellant. Readers will be attached to guns or be located in handling areas. When the propellant is passed near… 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.
