Abstract:Up to 2700 terawatt-hours per year of geothermal electricity generation capacity has been shown to be available within North America, typically with wells drilled into geologically active regions of the earths crust where this energy is concentrated (Huttrer, 2001). Of this potential, about half is… more
Abstract:ABSTRACT: The need for improved routing to support ad-hoc satellite communications is apparent and protocol research has been performed to date which would greatly impact future DoD systems. The Internet Router in Space (IRIS)technology developed by SEAKR and Cisco has provided an advantageous… more
Abstract:ABSTRACT: High-speed inter-satellite links (ISLs) are a key feature to improving satellite communications (SATCOM) bandwidth in support of global military operations. ISLs increase the number of paths in the network which tend to improve aggregate bandwidth, network survivability, and improve the… more
Abstract:Mixed phase clouds, i.e. those that contain water droplets and ice crystals, make up a large fraction of the clouds that are found over the Arctic region. The radiative impact of these clouds on climate modulation is highly sensitive to the relative mix of water and ice, the size distribution of… more

Abstract:ABSTRACT: The DF & NN baseline Dual Node Network (DNN) Data Fusion & Resource Management (DF & RM) technical architecture will be compared and extended. The multi-source DF & RM problem functional decomposition provided by DNN will be the framework for rigorous problem-to-solution… more
Abstract:ABSTRACT: To support emerging requirements for continuous and automated Space Situational Awareness (SSA), there must be an understanding of the root causes of anomalies, as this directly affects courses of action. To further SSA, one must accurately attribute anomalies to environment versus… more
Abstract:ABSTRACT: To support the JSpOC Mission System, AFRL needs to develop and test intelligent process management software that integrates diverse sets of automated distributed data fusion tools for multi-source correlated space superiority events. These tools need to be assessed during their use and… more
Abstract:A proposed new external pressure measurement data system for rotors and wings will use COTS components and specially designed hardware and software. The new measurement data system consists of two parts; a glove-like surface treatment that contains the pressure measurement devices and wires passing… more
Abstract:ABSTRACT: Next generation highly autonomous space vehicles need certain key technologies in order to achieve their promised goals. Much time is spent in mission planning working out the details of daily activities of space vehicle so as to assure adequate power/energy margin. The more autonomous… more
Abstract:ABSTRACT: A key problem in the rapid and lower cost development of spacecraft is that the various devices that comprise the spacecraft bus do not typically provide a single standard interface and/or communications protocols. This forces a design-to-order paradigm in which a spacecraft bus is… more
Abstract:Current DIRCM systems are effective against traditional reticle based seeker architectures. They project a modulated signal to confuse the seeker and divert it off its target. Missiles with modern seekers based on FPA imagers are being developed that are highly resistant to current DIRCM systems… more
Abstract:Monopropellants are readily ignited or decomposed over a bed of solid catalyst. A serious limitation of existing catalysts in the ignition of advanced monopropellants is limited thermal stability. The recent emphasis on improved performance of monopropellant technology (e.g., with AF M315E and… more
Abstract:Cold spray has many benefits compared to conventional thermal spray including lower deposition temperatures, higher bond strengths, less substrate preparation and better control of coating composition, phase structure, and oxide contamination. In cold spray, particles are accelerated by an expanding… 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: In high-speed weapon applications, typical forward-looking RF antenna sensors must reside near the nose. Unfortunately, this is the location that experiences the greatest amount of atmospheric ram pressure and thus thermal loading. As more and more advanced hypersonic weapons are… more
Abstract:ABSTRACT: As airborne sensors become more prolific and more sophisticated, the amount of data they are able to produce overwhelms the current ability to offload that data based on the meager performance of ground station terminals. A high gain antenna supporting Ka-Band sensor data offload and… more
Abstract:ABSTRACT: In order to provide modular, scalable, and flexible operational capabilities for future Joint Aerial Layer Networks, FIRST RF proposes developing a small, lightweight, robust, multi-band antenna concept that can be adapted to provide customizable"pick-and-choose"options,… more
Abstract:The future role of military ground and air vehicles is focused on wireless communications. These vehicles must accommodate a variety of sensors as well as antennas, not to mention traditional payloads such as fuel, weapons, and personnel. The integration of antennas on the vehicle is one of the… more
Abstract:While substantial progress has been made toward developing wideband, low-profile antennas, maintenance of reasonable gain at very low profiles and small diameters, especially as operating frequency is lowered, remains a problem. This is due to the fact that gain and antenna size are inversely… more
Abstract:ABSTRACT: Conformal, wideband and low frequency antennas are a persistent source of research and development for military and commercial integrators, particularly airframe integrators. Generally, conformal antennas are either narrow band or inefficient. Low frequency antennas are usually large and… more
Abstract:ABSTRACT: There are currently no antennas available for handheld receivers or other military systems that efficiently cover the full GNSS spectrum with broad, stable patterns and consistent performance over frequency. During the first phase of this program we designed, optimized and built working… more
Abstract:ABSTRACT: FIRST RF has developed a revolutionary new hybrid phased array architecture that provides two-axis beam agility not available in current hybrid antenna solutions. The hybrid solution combines mechanical pointing with electrical pointing to support communication links over a full… more
Abstract:ABSTRACT: Airborne ISR platforms are intensive data generators and require more robust SATCOM links in order to remain effective. One method of achieving higher datarates is by migrating to higher frequencies such as the 71 86 GHz band. This band is currently undeveloped, especially for… more
Abstract:The goals of this Phase II program are threefold. First, FIRST RF will enhance the current vest-integrated ground-radio (VIG-R) antenna to realize the instantaneous bandwidth required by the SINCGARS radio to provide full channel hopping capability. During the Phase I effort, FIRST RF demonstrated… 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.
