Abstract:TRIDENT SYSTEMS INCORPORATED PROPOSES TO DEFINE, DEVELOP SPECIFICATIONS FOR AND DEMONSTRATE PROOF-OF-CONCEPT FOR AN EXPERT SYSTEM BASED, AUTOMATED SOFTWARE TOOL TO ASSIST IN THE MEASUREMENT OF PERFORMANCE AND CORRECTNESS OF INFERENCE ENGINES. THE PROJECT INCLUDES DEFINITION OF A SET OF INFERENCE… more
Abstract:A necessary precursor to the design of modern time-critical computing applications is that the system requirements and constraints be u identified and organized. Several existing tools and methodologi to capture system requirements and constraints and to provide mechanisms to trace between… more
Abstract:The purpose of this SBIR Phase I proposal is to establish whether existing National Capabilities can be used to fulfill a key warfighting support requirement needed for planning and executing expeditionary warfare operations: providing, to the on-scene commander, accurate, up-to-date information on… more
Abstract:THERE IS A NEED TO REDUCE DOLPHIN BYCATCH IN THE TUNA PURSE SEINE FISHERY IN THE ETP AND IMPROVE THE SEARCHING EFFICIENCY FOR TUNAS NOT ASSOCIATED WITH DOLPHINS. ARETE PROPOSES TO DESIGN IN PHASE 1 A PROTOTYPE AIRBORNE PASSIVE DAYTIME MULTISPECTRAL IMAGING SYSTEM FOR IMPROVING THE SEARCHING… more
Abstract:Accurate estimate of the multipath channel parameters allow the associated errors to be cancelled which greatly improves GPS system navigation performance. A multi-parameter maximum likelihood estimation technique has been shown through simulations to be very effective in antimultipath processing.… more
Abstract:To achieve real-time ambiguity resolution (AR) in a high-dynamic environment, an algorithm is needed that is robut to cycle-slips and requires the minimum possible number of consecutive measurements before correctly resolving the ambiguities. The problem with existing AR algorithms is that they… more
Abstract:The ability to fuse data from sensors on both aircraft and weapon systems can significantly improve the accuracy of weapon delivery. NAVSYS has designed an innovative tracking system that optimally combines data from both the aircraft and missile sensors. This approach minimizes the required missile… more
Abstract:The proposed GPS Portable Landing Aid System (GPLAS) provides a highly accurate, fully autonomous system that is ideally suited to support V-22 missions. The GPLAS ground station includes a GPS reference receiver (RR) and a pseudolite (PL) which broadcasts the landing signal and GPS data corrections… more
Abstract:The goal of this project is to create tools to support the formal verification of VHDL designs. Two existing formal verification tools will be enhanced to support VHDL. The first, Spectool, will allow a class of designs, the synchronous finite-state controlled systems, to be specified and verified… more
Abstract:EXISTING COMMERCIAL MODELING AND SIMULATION SOFTWARE PACKAGES DO NOT ADEQUATELY PREDICT THE BEHAVIOR OF COMPLEX COMPUTER-CONTROLLED SYSTEMS BEING DEVELOPED AND FIELDED TODAY. THESE "HYBRID" SYSTEMS INVOLVE DISCONTINUOUS PHENOMENA SUCH AS MECHANICAL PARTS ENGAGING AND DISENGAGING (E.G., SPACECRAFT… more
Abstract:RADAR TARGET CLASSIFICATION CAN ENABLE IMPROVED ALLOCATION OF BATTLEFIELD RESOURCES, SUCH AS ASSIGNING WEAPONS TO THE MOST IMPORTANT CLASSES OF TARGETS. EXPERIMENTS HAVE SHOWN THAT GROUND VEHICLES AND HELICOPTERS HAVE DISTINGUISHING SPECTRAL COMPONENTS IN THEIR DOPPLER SIGNATURES. THESE KEY SPECTRAL… more
Abstract:The success of C3I and battle management systems depends critically on their ability to perform automatic target recognition (ATR) and hostile target identification (HTI). The technologies of sensor data fusion and adaptive signal processing including intelligent imaging are key to the success of… more
Abstract:The design of flight control systems involves the solution of several difficult optimization problems. Due to nonlinear dynamics, constraints on states and controls and modeling uncertainities, the flight control optimization problem involves local optima and nondifferentiable cost functions. This… 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.
